Yeah--in my suburb (on the peninsula between the Bay and the Pacific) it will get into the 90s a few days a year. Very rare that it will hit 100. We do get a little warmer than San Francisco, and a little colder in the winter. Normally it's about a 5 degree difference either way. 90 in San Francisco turns heads. That's really rare, I think.
In the winter, we drop below freezing only very occasionally. In San Francisco almost never. A typical winter morning for me is between 45 and 50. A typical summer morning is between 50 and 60--sometimes a little higher than that.
To BAB's point, the location around the Bay matters quite a bit. San Francisco is the cold point in the summer. North, South, or East it gets hotter. The further of any of those you get, the hotter it gets. San Jose can get pretty hot; Walnut Creek, and Sonoma/Napa the same. Likewise, in the winter, the further North, South, or East, the colder it gets. But, like where i live, it's rarely below freezing.
