What August feels like
August is as warm as the Pacific gets here, and the air carries a stickiness that surprises people who were promised dry California. South swell makes for the best bodysurfing of the year at Boomer and the La Jolla beaches.
Rain is genuinely rare — most years, August stays dry start to finish. There’s a little humidity in the air, but nothing that changes your plans.
Can you swim?
The ocean runs about 68° — brisk but swimmable.
