Val,
If this is the Golden West holiday, San Fran should be Mild to warm during the day and no lower than cool (coat/fleece) in the evening, it never gets really cold at any time.
From then onwards it will just get hotter with each place you visit.

Hi Mick,
First of all, nice to meet you.
Yes it's the Golden West I'm looking at, still thinking though...nerves!
Thank you for letting me know about the weather.
Val
