Morning frost and afternoon heat
The temperature in the San Francisco Bay area drops below freezing overnight pretty regularly during the late fall and into the winter. The same thing happens out in the desert actually. But along the coast, the marine layer fog and dew will end up freezing, leaving a tiny layer of ice all over the grass and trees in the early morning. It all melts away by the time the sun is all the way up, and is not a good predictor of the high temperature for the day. So coastal Californians are really adept at dressing in layers, with the assumption that three or so combinations will be needed to get through the day. Jacket + sweater first thing in the morning, jacket off but sweater on late morning, sweater off and jacket off mid-day, then sweater back on, something like that. Chameleon like.
