I’m not sure how Californians relate to the change in seasons like we do east of the Rockies, but if they do identify with the seasons, then the air in Los Angeles last weekend was positively fall like. Temperatures were in the 70s in the afternoon, with 50s overnight. If there were deciduous trees in LA, I would think to do some leaf peeping. One thing to take a look at in Los Angeles, though, is the forecast you might get from Weatherbug. They were nearly perfect for a good weather weekend forecast. The gold standard, truly.
Actuals: Saturday, High 71, Low 56
Sunday, High 78, Low 55
