"Summer has always been my favorite season. I feel happier," the 500 Days of Summer tells Self for its August issue.
Deschanel, 29, says the fun begins on the grass. The best way to enjoy, she says, is to wear "all-green and roll down a hill." In other fashion tips, Deschanel says you can't go wrong with a hat: boaters for guys and bonnets for the ladies. For food, Deschanel suggests cold pea soup and strawberry jam.
Of course, it must be eaten outside: "Nothing's better than a picnic," she says.
Music is also essential – Deschanel is the "she" in the singing duo She & Him) – and the Beach Boys really set the tune. She considers hearing Brian Wilson perform an outdoor concert at the Hollywood Bowl as a most classic summer memory and includes "Wouldn't It Be Nice?" on her summer song play list.
