I personally find SF Bay Area weather terrible, terrible. SF has the same weather year round and it is as follows:
* Uncomfortably warm during the day
* Uncomfortably cold during the night
* A lot of unpredictable and long-running showers, rain and fog
* A lot of cold wind year-round (especially summer, see below)
I found the following quote by Mark Twain very accurate:
> The coldest winter I ever spent was a summer in San Francisco.
I also personally experienced that, although summers and winters in SF have the same weather (as explained above) somehow summers tend to be colder especially during night and in shades.
I think it just sucks. If you like that's great.
