Olaf sings “In Summer” while imagining how wonderful warm weather would be in Disney’s Frozen.
The song appears after Olaf has joined Anna and Kristoff on their journey. Olaf is a snowman brought to life by Elsa’s magic, yet he dreams enthusiastically about experiencing summer. The central joke is that he does not understand that heat would cause him to melt.
“In Summer” was written by Kristen Anderson-Lopez and Robert Lopez, the songwriting team behind Frozen’s original songs. Josh Gad performs the song as Olaf in the English-language version. Its bright arrangement and deliberately comic lyrics contrast with the film’s colder visual setting.
The song is often confused with “Some Things Never Change,” which opens Frozen II. “In Summer” belongs to the first Frozen film and is specifically Olaf’s solo number about warm weather.
