A delivery or ball in cricket is a single action of bowling a cricket ball toward the batsman. During play of the game, a member of the fielding team is designated as the bowler, bowls deliveries toward the batsman. Six legal balls in a row constitutes an over, after which a different member of the fielding side takes over the role of bowler for the next over; the bowler delivers the ball from his or her end of the pitch toward the batsman standing at the opposite wicket at the other end of the pitch. Bowlers can be either right-handed; this approach to their delivery, in addition to their decision of bowling around the wicket or over the wicket, is knowledge of which the umpire and the batsman are to be made aware. Deliveries can be made by spin bowlers. Fast bowlers tend to make the ball either move off the pitch or move through the air, while spinners make the ball "turn" either toward a right-handed batsman or away from him; the ball can bounce at different distances from the batsman, this is called the length of the delivery.
It can range from a bouncer to a yorker. There are many different types of delivery; these deliveries vary by: technique, the hand the bowler bowls with, use of the fingers, use of the seam, how the ball is positioned in the hand, where the ball is pitched on the wicket, the speed of the ball, the tactical intent of the bowler.

Throughout an over, the bowler will choose a sequence of deliveries designed to attack the batsman's concentration and technique, in an effort to get him out.
The bowler varies the amount of loop and pace imparted to various deliveries to try to cause the batsman to misjudge and make a mistake. As the crease has a width, the bowler can change the angle from which he delivers to the batsman in an attempt to induce a misjudgement; the bowler decides what type of delivery to bowl next, without consultation or informing any other member of his team. Sometimes, the team captain will offer advice or issue a direct order regarding what deliveries to bowl, based on his observations of the batsman and the strategic state of the game. Another player who offers advice to the bowler is the wicket-keeper, since he has a unique view of the batsman and may be able to spot weaknesses of technique. Another piece of information important for the bowlers to consider prior to their deliveries is the state of pitch; the pitch is a natural ground and its state is subjected to variation over the course of the cricket, some of which are multi-day events such as test matches.
Spinners find an old pitch, one, used, more suitable to their deliveries rather than a fresh pitch, one that hasn't come under use as much such as a pitch at the start of the match. While a bowler, with the use of variations in his/her delivery aims to target the concentration of batsmen as well as their skill and technique of batting, anticipation of the delivery is crucial for the batsman, as emphasised by Jodi Richardson. Richardson reveals the world class batsman's dilemma while facing fast bowlers, stating that the time between the batsmen's anticipation of the trajectory of the ball and positioning themselves for the appropriate shot can be twice as long as the interval between the ball leaving the bowler's hand and reaching the batsman's crease. Side by side, Richardson alludes to the research undertaken by Dr. Sean Müller in Australia, funded by Cricket Australia's Centre of Excellence; the results of the research demonstrated the importance of anticipation of the delivery for batsmen in cricket.
They revealed that experienced batsmen possessed a unique ability which enabled them to adjust their feet as well as their positioning on the crease accordingly based upon their reading of the body language and movements enacted by the bowler prior to the release of the ball. This foresight that batsmen use while on the crease is referred to as'advance information' by Richardson. Moreover, Müller's research outlined that the presence of this'advance information' was not as evident among the lesser skilled batsmen in comparison to the experienced ones. Underarm or lob bowling was the original cricket delivery style,but had died out before the 20th century, although it was used until 1910 by George Simpson-Hayward, remained a legal delivery type. On 1 February 1981, when Australia was playing New Zealand in a One Day International cricket match, New Zealand needed six runs to tie the match from the final ball. Greg Chappell, the Australian captain, ordered the bowler to bowl underarm, rolling the ball along the ground to prevent the Number 10 New Zealand batsman any chance of hitting a six from the last ball to tie the match.
After the game, the Prime Minister of New Zealand, Rob Muldoon, described it as "the most disgusting incident I can recall in the history of cricket." At the time, underarm deliveries were legal, but as a direct result of the incident, underarm bowling was banned in limi
Cricket is a bat-and-ball game played between two teams of eleven players on a field at the centre of, a 20-metre pitch with a wicket at each end, each comprising two bails balanced on three stumps. The batting side scores runs by striking the ball bowled at the wicket with the bat, while the bowling and fielding side tries to prevent this and dismiss each player. Means of dismissal include being bowled, when the ball hits the stumps and dislodges the bails, by the fielding side catching the ball after it is hit by the bat, but before it hits the ground; when ten players have been dismissed, the innings ends and the teams swap roles. The game is adjudicated by two umpires, aided by a third umpire and match referee in international matches, they communicate with two off-field scorers. There are various formats ranging from Twenty20, played over a few hours with each team batting for a single innings of 20 overs, to Test matches, played over five days with unlimited overs and the teams each batting for two innings of unlimited length.
Traditionally cricketers play in all-white kit, but in limited overs cricket they wear club or team colours. In addition to the basic kit, some players wear protective gear to prevent injury caused by the ball, a hard, solid spheroid made of compressed leather with a raised sewn seam enclosing a cork core, layered with wound string. Cricket's origins are uncertain and the earliest definite reference is in south-east England in the middle of the 16th century, it spread globally with the expansion of the British Empire, leading to the first international matches in the second half of the 19th century. The game's governing body is the International Cricket Council, which has over 100 members, twelve of which are full members who play Test matches; the game's rules are held in a code called the Laws of Cricket, owned and maintained by Marylebone Cricket Club in London. The sport is followed in the Indian subcontinent, the United Kingdom, southern Africa and the West Indies, its globalisation occurring during the expansion of the British Empire and remaining popular into the 21st century.
Women's cricket, organised and played separately, has achieved international standard. The most successful side playing international cricket is Australia, having won seven One Day International trophies, including five World Cups, more than any other country, having been the top-rated Test side more than any other country. Cricket is one of many games in the "club ball" sphere that involve hitting a ball with a hand-held implement. In cricket's case, a key difference is the existence of a solid target structure, the wicket, that the batsman must defend; the cricket historian Harry Altham identified three "groups" of "club ball" games: the "hockey group", in which the ball is driven to and fro between two targets. It is believed that cricket originated as a children's game in the south-eastern counties of England, sometime during the medieval period. Although there are claims for prior dates, the earliest definite reference to cricket being played comes from evidence given at a court case in Guildford on Monday, 17 January 1597.
The case concerned ownership of a certain plot of land and the court heard the testimony of a 59-year-old coroner, John Derrick, who gave witness that: "Being a scholler in the ffree schoole of Guldeford hee and diverse of his fellows did runne and play there at creckett and other plaies". Given Derrick's age, it was about half a century earlier when he was at school and so it is certain that cricket was being played c. 1550 by boys in Surrey. The view that it was a children's game is reinforced by Randle Cotgrave's 1611 English-French dictionary in which he defined the noun "crosse" as "the crooked staff wherewith boys play at cricket" and the verb form "crosser" as "to play at cricket". One possible source for the sport's name is the Old English word "cryce" meaning a staff. In Samuel Johnson's Dictionary, he derived cricket from "cryce, Saxon, a stick". In Old French, the word "criquet" seems to have meant a kind of stick. Given the strong medieval trade connections between south-east England and the County of Flanders when the latter belonged to the Duchy of Burgundy, the name may have been derived from the Middle Dutch "krick", meaning a stick.
Another possible source is the Middle Dutch word "krickstoel", meaning a long low stool used for kneeling in church and which resembled the long low wicket with two stumps used in early cricket. According to Heiner Gillmeister, a European language expert of Bonn University, "cricket" derives from the Middle Dutch phrase for hockey, met de sen. Gillmeister has suggested that not only the name but the sport itself may be of Flemish origin. Although the main object of the game has always been to score the most runs, the early form of cricket differed from the modern game in certain key technical aspects; the ball was bowled underarm by the bowler and all along the ground towards a batsman armed with a bat that, in shape, resembled a hockey stick.
Batting average (cricket)
In cricket, a player's batting average is the total number of runs they have scored divided by the number of times they have been out. Since the number of runs a player scores and how they get out are measures of their own playing ability, independent of their teammates, batting average is a good metric for an individual player's skill as a batter; the number is simple to interpret intuitively. If all the batter's innings were completed, this is the average number of runs they score per innings. If they did not complete all their innings, this number is an estimate of the unknown average number of runs they score per innings; each player has several batting averages, with a different figure calculated for each type of match they play, a player's batting averages may be calculated for individual seasons or series, or at particular grounds, or against particular opponents, or across their whole career. Batting average has been used to gauge cricket players' relative skills since the 18th century.
Most players have career batting averages in the range of 20 to 40. This is the desirable range for wicket-keepers, though some fall short and make up for it with keeping skill; until a substantial increase in scores in the 21st century due to improved bats and smaller grounds among other factors, players who sustained an average above 50 through a career were considered exceptional, before the development of the heavy roller in the 1870s an average of 25 was considered good. All-rounders who are more prominent bowlers than batsmen average something between 20 and 30. 15 and under is typical for specialist bowlers. A small number of players have averaged less than 5 for a complete career, though a player with such an average is a liability unless an exceptional bowler as Alf Valentine, B. S. Chandrasekhar or Glenn McGrath were. Career records for batting average are subject to a minimum qualification of 20 innings played or completed, in order to exclude batsmen who have not played enough games for their skill to be reliably assessed.
Under this qualification, the highest Test batting average belongs to Australia's Sir Donald Bradman, with 99.94. Given that a career batting average over 50 is exceptional, that only five other players have averages over 60, this is an outstanding statistic; the fact that Bradman's average is so far above that of any other cricketer has led several statisticians to argue that, statistically at least, he was the greatest athlete in any sport. Disregarding this 20 innings qualification, the highest career test batting average is 112, by Andy Ganteaume, a Trinidadian Keeper-batsman, dismissed for 112 in his only test innings. Batting averages in One Day International cricket tend to be lower than in Test cricket, because of the need to score runs more and take riskier strokes and the lesser emphasis on building a large innings, it should be remembered in relation to the ODI histogram above, that there were no ODI competitions when Bradman played. If a batter has been dismissed in every single innings this statistic gives the average number of runs they score per innings.
However, for a batter with innings which finished not out, the true average number of runs they score per innings is unknown as it is not known how many runs they would have scored if they could have completed all their not out innings. This statistic is an estimate of the average number of runs. If their scores have a geometric distribution this statistic is the maximum likelihood estimate of their true unknown average. Batting averages can be affected by the number of not outs. For example, Phil Tufnell, noted for his poor batting, has an respectable ODI average of 15, despite a highest score of only 5 not out, as he scored an overall total of 15 runs from 10 innings, but was out only once. A batter who has not been dismissed in any of the innings over which their average is being calculated does not have a batting average, as dividing by zero does not give a result.

Alternative measures of batting effectiveness have been developed, including: Strike rate measures a different concept to batting average – how the batter scores – so it does not supplant the role of batting average, it is used in limited overs matches, where the speed at which a batter scores is more important than it is in first-class cricket. A system of player rankings was developed to produce a better indication of players' current standings than is provided by comparing their averages. Cricket statistics Batting average Bowling average
West Indies cricket team
The West Indies cricket team, traditionally known as the Windies, is a multi-national cricket team representing the Anglophone Caribbean region and administered by Cricket West Indies. The players on this composite team are selected from a chain of fifteen Caribbean territories, which are parts of several different countries and dependencies; as of 24 June 2018, the West Indian cricket team is ranked ninth in the world in Tests, ninth in ODIs and seventh in T20Is in the official ICC rankings. From the mid-late 1970s to the early 1990s, the West Indies team was the strongest in the world in both Test and One Day International cricket. A number of cricketers who were considered among the best in the world have hailed from the West Indies: Sir Garfield Sobers, Lance Gibbs, George Headley, Brian Lara, Clive Lloyd, Malcolm Marshall, Sir Andy Roberts, Rohan Kanhai, Sir Frank Worrell, Sir Clyde Walcott, Sir Everton Weekes, Sir Curtly Ambrose, Michael Holding, Courtney Walsh, Joel Garner, Sir Viv Richards and Sir Wes Hall have all been inducted into the ICC Hall of Fame.
The West Indies have won the ICC Cricket World Cup twice, the ICC World Twenty20 twice, the ICC Champions Trophy once, the ICC Under 19 Cricket World Cup once, have finished as runners-up in the Cricket World Cup, the Under 19 Cricket World Cup, the ICC Champions Trophy. The West Indies appeared in three consecutive World Cup finals, were the first team to win back-to-back World Cups; the West Indies has hosted the 2007 Cricket World Cup and the 2010 ICC World Twenty20. The current side represents: Sovereign states Antigua and BarbudaL Barbados DominicaW GrenadaW Guyana Jamaica Saint LuciaW Saint Vincent and the GrenadinesW Trinidad and Tobago Parts of Saint Kitts and Nevis Saint KittsL NevisL British Overseas Territories AnguillaL MontserratL British Virgin IslandsL Constituent country of the Kingdom of the Netherlands Sint MaartenL Territory of the United States US Virgin IslandsLLegends L = Participant of the Leeward Islands team and member of the Leeward Islands Cricket Association W = Participant of the Windward Islands team and member of the Windward Islands Cricket Board of ControlNotes Cricket West Indies, the governing body of the team, consists of the six cricket associations of Barbados, Jamaica and Tobago, Leeward Islands and Windward Islands.
The Leeward Islands Cricket Association consists of associations of one sovereign state, the two entities of Saint Kitts and Nevis, three British Overseas Territories and two other dependencies. The Windward Islands Cricket Board of Control consists of associations of four sovereign states. Cayman Islands and Turks and Caicos Islands, other historical parts of the former West Indies Federation and now British Overseas Territories, have their own teams. National teams exist for the various islands, which, as they are all separate countries much keep their local identities and support their local favourites; these national teams take part in the Carib Beer Cup. It is common for other international teams to play the island teams for warm-up games before they take on the combined West Indies team; the population of these countries and dependencies is estimated at around 6 million, more than Scotland and the Republic of Ireland. The member associations of Cricket West Indies are: Barbados Cricket Association Guyana Cricket Board Jamaica Cricket Association Trinidad & Tobago Cricket Board Leeward Islands Cricket Association.
The WICB joined the sport's international ruling body, the Imperial Cricket Conference, in 1926, played their first official international match, granted Test status, in 1928, thus becoming the fourth Test nation. In their early days in the 1930s, the side represented the British colonies that would form the West Indies Federation plus British Guiana; the last series the West Indies played before the outbreak of the Second World War was against England in 1939. There followed a hiatus. Of the West Indies players in that first match after the war only Gerry Gomez, George Headley, Jeffrey Stollmeyer, Foffie Williams had played Test cricket. In 1948, leg spinner Wilfred Ferguson became the first West Indian bowler to take ten wickets in a Test, finishing with 11/229 in a match against England.
Stumped is a method of dismissal in cricket. The action of stumping can only be performed by a wicket-keeper and, according to the Laws of Cricket, a batsman can be given out stumped if: the wicket-keeper puts down the wicket, while the batsman is: out of his ground. Being "out of his ground" is defined as not having any part of the batsman's body or his bat touching the ground behind the crease – i.e. if his bat is elevated from the floor despite being behind the crease, or if his foot is on the crease line itself but not across it and touching the ground behind it he would be considered out. One of the fielding team must appeal for the wicket by asking the umpire; the appeal is directed to the square-leg umpire, who would be in the best position to adjudicate on the appeal. Stumping is the fifth most common form of dismissal after caught, leg before wicket and run out, though it is seen more in Twenty20 cricket because of its more aggressive batting, it is governed by Law 39 of the Laws of Cricket.
It is seen with a medium or slow bowler, as with fast bowlers a wicket-keeper takes the ball too far back from the wicket to attempt a stumping. It includes co-operation between a bowler and wicket-keeper: the bowler draws the batsman out of his ground, the wicket-keeper catches and breaks the wicket before the batsman realises he has missed the ball and makes his ground, i.e. places the bat or part of his body on the ground back behind the popping crease. If the bails are removed before the wicket-keeper has the ball, the batsman can still be stumped if the wicket-keeper removes one of the stumps from the ground, while holding the ball in his hand; the bowler is credited for the batsman's wicket, the wicket-keeper is credited for the dismissal. A batsman may be out stumped off a wide delivery but cannot be stumped off a no-ball as bowler is credited for the wicket. Notes: The popping crease is defined as the back edge of the crease marking (i.e. the edge closer to the wicket. Therefore, a batsman whose bat or foot is on the crease marking, but does not touch the ground behind the crease marking, can be stumped.
This is quite common. The wicket must be properly put down in accordance with Law 28 of the Laws of cricket: using either the ball itself or a hand or arm, in possession of the ball. Note that since the ball itself can put down the wicket, a stumping is still valid if the ball rebounds from the'keeper and breaks the wicket though never controlled by him; the wicket-keeper must allow the ball to pass the stumps before taking it, unless it has touched either the batsman or his bat first. If the wicket-keeper fails to do this, the delivery is a "no-ball", the batsman cannot be stumped
Port of Spain
Port of Spain the City of Port of Spain, is the capital city of Trinidad and Tobago and the country's second-largest city after San Fernando and the third largest municipality after Chaguanas and San Fernando. The city has a municipal population of 37,074, an urban population of 81,142 and a transient daily population of 250,000, it is located on the Gulf of Paria, on the northwest coast of the island of Trinidad and is part of a larger conurbation stretching from Chaguaramas in the west to Arima in the east with an estimated population of 600,000. The city serves as a retail and administrative centre and it has been the capital of the island since 1757, it is an important financial services centre for the Caribbean and is home to two of the largest banks in the region. Port of Spain was the de facto capital of the short-lived West Indies Federation, which united the Caribbean. Caricom was established in Chaguaramas, west of Port of Spain; the city is home to the largest container port on the island and is one of several shipping hubs of the Caribbean, exporting both agricultural products and manufactured goods.
Bauxite from Guyana is trans-shipped via facilities at Chaguaramas, about 8 kilometres west of the city. The pre-lenten Carnival is tourist attraction. Today, Port of Spain is a leading city in the Caribbean region. Trinidad and Tobago hosted the Fifth Summit of the Americas in 2009 whose guests included US President Barack Obama and US Secretary of State Hillary Clinton. Port of Spain is home to the biggest and most successful stock exchange in the Caribbean, the Trinidad and Tobago Stock Exchange; the iconic Nicholas Tower, as well as other skyscrapers, are well known throughout the region. These buildings dominate the city's skyline; some of the tallest skyscrapers in the Caribbean are located in Port of Spain. The Port of Spain was founded near the site of the Amerindian fishing village of Cumucurapo, located in the area today known as Mucurapo, west of the city centre; the name Conquerabia is recorded for an Amerindian settlement in this area. In 1560, a Spanish garrison was posted near the foot of the Laventille Hills, which today form the city's eastern boundary.
The part of today's downtown Port of Spain closest to the sea was once an area of tidal mudflats covered by mangroves. The first Spanish buildings here, in the 16th and 17th centuries, were open mud-plastered ajoupas, interspersed between large silk cotton trees and other trees; the fort was a mud-walled enclosure with a shack inside, a flagpole, two or three cannon, few Spanish soldiers. This was captured during Walter Raleigh's expedition in April 1595; the Caribs were transient, travelling up the Orinoco River. The French naval commander Comte D'Estrées visited in 1680, reported that there was no Port of Spain, but in 1690, Spanish governor Don Sebastien de Roteta reported in writing to the King of Spain: In 1699, the alcalde of Trinidad reported to the king that the natives "were in the habit of showering scorn and abuse upon the Holy Faith and ridiculed with jests the efforts of the Holy Fathers". By 1757, the old capital, San José de Oruña, about 11 kilometres inland, had fallen into disrepair, Governor Don Pedro de la Moneda transferred his seat to Port of Spain, which thus became Trinidad's de facto capital.
The last Spanish Governor of Trinidad, Don José Maria Chacón, devoted much of his time to developing the new capital. He compelled the island's Cabildo to move to Port of Spain, he limited its powers to the municipality; the 1783 Cedula of Population, which encouraged the settlement of French Catholics in the island, led to a rapid increase in the town's population and its geographical extension westwards. From the small cluster of buildings at the foot of the Laventille Hills, eleven streets were laid out west to the area bounded by the St. Ann's River, thus establishing the grid pattern which has survived in downtown Port of Spain to the present day. Along the sea shore was the Plaza de la Marina, a parade ground. By 1786, the town had a population of about 3,000. Realising that the St. Ann's River, prone to flooding, was impeding the expansion of the town, Chacón had its course diverted in 1787 so that it ran to the east of the city, along the foot of the Laventille Hills. Port of Spain was now able to continue spreading northwards and westwards, encroaching on the surrounding sugar-cane plantations.
In 1797, Trinidad was invaded by a British force under General Sir Ralph Abercromby. The British landed west of Port of Spain, at what is still called Invaders Bay, marched towards the town. Realising his military resources were inadequate to defend the colony and wishing to avoid unnecessary destruction, Governor Chacón capitulated and was able to negotiate generous terms with Abercromby. Port of Spain remained the capital. In 1803, Port of Spain began growing southwards, with the re
Trinidad and Tobago
Trinidad and Tobago the Republic of Trinidad and Tobago, is a twin island country, the southernmost nation of the West Indies in the Caribbean. It is situated 130 kilometres south of Grenada off the northern edge of the South American mainland, 11 kilometres off the coast of northeastern Venezuela, it shares maritime boundaries with Barbados to the northeast, Grenada to the northwest, Guyana to the southeast, Venezuela to the south and west. The island of Trinidad was a Spanish colony from the arrival of Christopher Columbus in 1498 until Spanish governor Don José María Chacón surrendered the island to a British fleet under the command of Sir Ralph Abercromby in 1797. During the same period, the island of Tobago changed hands among Spanish, French and Courlander colonisers more times than any other island in the Caribbean. Trinidad and Tobago were ceded to Britain in 1802 under the Treaty of Amiens as separate states and unified in 1889. Trinidad and Tobago obtained independence in 1962 and became a republic in 1976.
As of 2015, the sovereign state of Trinidad and Tobago had the third highest GDP per capita based on purchasing power parity in the Americas after the United States and Canada. It is recognised by the World Bank as a high-income economy. Unlike most of the English-speaking Caribbean, the economy is industrial with an emphasis on petroleum and petrochemicals. Trinidad and Tobago is known for its Carnival and Diwali celebrations and as the birthplace of steelpan, the limbo, music styles such as calypso, soca and chutney. Historian E. L. Joseph claimed that Trinidad's Amerindian name was Cairi or "Land of the Humming Bird", derived from the Arawak name for hummingbird, ierèttê or yerettê. However, other authors dispute this etymology with some claiming that cairi does not mean hummingbird and some claiming that kairi, or iere means island. Christopher Columbus renamed it "La Isla de la Trinidad", fulfilling a vow made before setting out on his third voyage of exploration. Tobago's cigar-like shape may have given it its Spanish name and some of its other Amerindian names, such as Aloubaéra and Urupaina, although the English pronunciation is /təˈbeɪɡoʊ/, rhyming with lumbago, "may go".
Trinidad and Tobago are islands situated between 10° 2' and 11° 12' N latitude and 60° 30' and 61° 56' W longitude. At the closest point, Trinidad is just 11 kilometres from Venezuelan territory. Covering an area of 5,128 km2, the country consists of the two main islands and Tobago, numerous smaller landforms, including Chacachacare, Huevos, Gaspar Grande, Little Tobago, St. Giles Island. Trinidad is 4,768 km2 in area with an average length of 80 kilometres and an average width of 59 kilometres. Tobago has an area of about 300 km2, or 5.8% of the country's area, is 41 km long and 12 km at its greatest width. Trinidad and Tobago lie on the continental shelf of South America, are thus geologically considered to lie in South America; the terrain of the islands is a mixture of plains. The highest point in the country is found on the Northern Range at El Cerro del Aripo, 940 metres above sea level; as the majority of the population lives on the island of Trinidad, this is the location of most major towns and cities.
There are four major municipalities in Trinidad: Port of Spain, the capital, San Fernando and Chaguanas. The main town in Tobago is Scarborough. Trinidad is made up of a variety of soil types, the majority being heavy clays; the alluvial valleys of the Northern Range and the soils of the East–West Corridor are the most fertile. The Northern Range consists of Upper Jurassic and Cretaceous metamorphic rocks; the Northern Lowlands consist of younger shallow marine clastic sediments. South of this, the Central Range fold and thrust belt consists of Cretaceous and Eocene sedimentary rocks, with Miocene formations along the southern and eastern flanks; the Naparima Plains and the Nariva Swamp form the southern shoulder of this uplift. The Southern Lowlands consist of Miocene and Pliocene sands and gravels; these overlie oil and natural gas deposits north of the Los Bajos Fault. The Southern Range forms the third anticlinal uplift, it consists of several chains of hills, most famous being the Trinity Hills.
The rocks consist of sandstones, shales and clays formed in the Miocene and uplifted in the Pleistocene. Oil sands and mud volcanoes are common in this area; the climate is tropical. There are two seasons annually: the dry season for the first five months of the year, the rainy season in the remaining seven of the year. Winds are dominated by the northeast trade winds. Unlike most of the other Caribbean islands, both Trinidad and Tobago have escaped the wrath of major devastating hurricanes, including Hurricane Ivan, the most powerful storm to have passed close to the islands in recent history, in September 2004. In the Northern Range, the climate is different in contrast to the sweltering heat of the plains below. With constant cloud and mist cover, heavy rains in the mountains, the temperature is much cooler. Record temperatures for Trinidad and Tobago are 39 °C for the high in Port of Spain, a low of 12 °C; because Trinidad and Tobago lies
