1. It’s always sunny and sometimes hot
Aside from some occasional morning fog (most common during a late-spring period dubbed May Gray and June Gloom), you can expect it to be sunny almost 300 days out of the year. While winter can bring some wet days, you likely 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, mostly in the late summer and early fall.
