I live in San Francisco and it ROCKS!
Pimpdog if you're moving just for kicks and there is no true "reason" behind San Jose then i would totaly recommend SF instead. And since you like the ocean it's right on the coast. I'm 2 blocks from the beach. Only problem is that the water is fucking freezing, lol.
Keep in mind though that while the weather overal is great and never gets too cold in never gets too hot here either. We get fog and rain even in the summer. It's not like LA weather were you actually have hot weather all summer long. Actually our summer is more Aug,Sept,Oct....indian summer. San Jose on the other hand actually gets hot in the summer and stays that way the whole time. The weather is waaaay nicer there.
And of course being a major city SF does have some fun ass places to party. You can go out any night of the week and find somewhere that's happening.
SF Rules!
