LA is not a desert in the sense used by climatologists.

LA is in the Mediterranean climate zone. If you are willing to entertain the idea that not just Los Angeles, but San Francisco is in a desert -- I have no words. Have you been there? People, typically not very well-informed about California geography and the Southwest, do sometimes lazily refer to LA as a desert. They seem to do this because they have heard other people do it. If you have lived here, you will see how evidently wrong this is. It's July and I can take my dog to a creek that has flowing water. This is not something you can do in a desert. Have you been to an actual desert, such as the Mojave, the Sonora, or the Anza-Borrego?
