The weather in western Los Angeles, USA

It's sunny in Los Angeles during the day, but as long as there is a shady place, it's cool, absolutely not sweating, and it's a little cold at night, so you may need to add a thin coat. I have been in Los Angeles for five years, and I like the climate here very much. As long as it is not hot when I sleep, it will be cold when I open the window at night. The weather in new york is very similar to that in the northeast of China, with four distinct seasons. Chicago has never been there.
