Coachella is held in Indio, California, which is in the Mojave Desert. The desert climate means that it gets very hot during the day, but it does cool down at night. The average high temperature in April, when Coachella takes place, is 92 degrees Fahrenheit. However, the average low temperature is a more comfortable 64 degrees Fahrenheit. So, while you will need to wear sunscreen and drink plenty of water during the daytime hours, you will probably want to pack a light jacket for the evening.
