1. It’s always sunny and sometimes hot
Aside from some morning fog, you can expect it to be sunny almost 300 days out of the year. While winter can bring a few wet days, you won’t see a drop of rain in the summer. Temperatures by the ocean hover comfortably in the 70s nearly all year; if you’re venturing into the Valley, though, expect occasional (but increasingly frequent) triple-digit days in the late summer and early fall.
