Tropical Storm Max was the first of four tropical cyclones to make landfall along the Pacific Coast of Mexico in October 2023. The sixteenth tropical depression and thirteenth named storm of the 2023 Pacific hurricane season, Max originated from a trough that developed to the southwest of Central America on October 3, 2023. Showers and thunderstorms associated with the disturbance gradually became better organized over the following days as it moved west-northwestwards to the south of Mexico. The disturbance was designated Potential Tropical Cyclone Sixteen-E on October 7 by the United States National Hurricane Center (NHC), as it had not yet become a tropical cyclone but was threatening the southwestern coast of Mexico. The disturbance developed a more well-defined circulation the following day and developed into a tropical depression; the depression strengthened into a tropical storm late on October 8 and was assigned the name Max. Max progressed northward toward the coast of Mexico and quickly strengthened; the storm made landfall near Puerto Vicente, Guerrero at 18:00 UTC on October 9 just below hurricane strength. Max rapidly weakened as it moved inland across southern Mexico and dissipated the following morning over the region's mountainous terrain.

During 2023, tropical cyclones formed in seven major bodies of water, commonly known as tropical cyclone basins. They were named by various weather agencies when they attained maximum sustained winds of 35 knots. Throughout the year, a total of 115 systems formed, with 79 of them being named. The most intense storm this year was Typhoon Mawar, which had a minimum pressure of 900 hPa (26.58 inHg). The deadliest tropical cyclone of the year was Storm Daniel, which killed at least 10,028 people in Libya, Greece, Turkey, and Bulgaria. Meanwhile, the costliest tropical cyclone was Typhoon Doksuri which caused at least US$28.4 billion worth of damage in China, the Philippines and Taiwan, becoming the costliest on record outside the Atlantic Ocean basin. Among this year's systems, thirty became major tropical cyclones, of which nine intensified into Category 5 tropical cyclones on the Saffir–Simpson scale (SSHWS). This year, for the first time on record, at least one such Category 5 system formed in each tropical cyclone basin: Typhoons Mawar and Bolaven in the western Pacific Ocean, Hurricanes Jova and Otis in the eastern Pacific, Hurricane Lee in the Atlantic, Cyclone Mocha in the North Indian Ocean, Cyclone Freddy in the southwest Indian Ocean, Cyclone Ilsa in the Australian region, and Cyclone Kevin in the South Pacific. The accumulated cyclone energy (ACE) index for the 2023, as calculated by Colorado State University (CSU) was 857.4 units, which was above the 1991-2020 mean of 770.2 units.
