Well, here in San Francisco its cold and foggy today, but due to warm up and have some sun tomorrow. Next week its supposed to be sunny and in the mid 70'sF. Away from the coast though, its will be very warm. Probably around 90F or so. I live in the San Francisco Bay Area (inland) and I love San Francisco. Many wonderful restaurants here, but if you're fasting that might be tough. Good luck!
Enjoy your trip.
