Yeah, I should have mentioned temperature. I'm in Los Gatos, too, and it's not San Diego. I've seen snow in Redding several times, though it's not common. Nice during the day here today, though--T-shirt weather.
Depends on what you're used to, of course. When I lived in SoCal, I thought 60 was brisk. Now that I ride in Reno, that's about when I break out the long-sleeved T-shirt.
