I live near Los Angeles and was freezing my nuts off about 3 1/2 weeks ago.
The farther you live from the coast, the colder it can get overnight in the winter, but those areas tend to be warmer in Santa Anas, too. In the summer, as you well know, it gets very hot inland, while the coast stays moderate.
Point being, in a global cooling situation, which we have now, the warmer climes will be the place to be.
