"Let It Snow! Let It Snow! Let It Snow!", also known as "Let It Snow", is a song written by lyricist Sammy Cahn and composer Jule Styne in July 1945. It was written in Hollywood, California during a heat wave as Cahn and Styne imagined cooler conditions. Despite the lyrics making no mention of Christmas the song became associated with Christmas music due to being played on radio stations during the Christmas and holiday season and having often been covered by various artists on Christmas-themed albums. In the Southern Hemisphere, however, it can be played during winter (June, July, August) and in New Zealand, some play it at Matariki.
