It Was Hot, We Stayed in the Water, sometimes shortened to It Was Hot, is the second studio album by American indie folk and indie rock band the Microphones. It was released by K Records on September 26, 2000. After Phil Elverum—the frontman, principal songwriter, and producer of the Microphones's albums—had gained a small following with 1999's Don't Wake Me Up, he recorded It Was Hot in Dub Narcotic Studio in Olympia, Washington, between September 1999 and March 2000. The album was recorded on analogue tape; Elverum embraced the medium's technical imperfections. The album was described as indie rock, lo-fi, and indie pop and was inspired by Elverum's visits to the ocean. As a whole, the album centers on the theme of water, while its lyricism is heavily themed on nature. The 11-minute track "The Glow" acts as the album's climax and introduces the concept of the "glow", which was explored in more depth on 2001's The Glow Pt. 2.

The Microphones were an American indie folk, indie rock, and experimental project from Olympia, Washington. The project was founded in 1996 and ended in 2003, with a short reunion following in 2007 and revivals in 2019 and 2020. Across every iteration of the Microphones, it has been fronted by Phil Elverum. Elverum is the principal songwriter and producer behind the band's albums, but he has also collaborated with other local musicians on his other recordings and tours. Many of Elverum's recordings from the project's initial period were released by the label K Records.
