Nyetzy: "Hey, you guys hijacked my post .
Seriously what is tne temperature like in Dec?

Well it might have been "hijacked" - but if you read all those posts -- your question most definitely was answered. Obviously there is no way to tell you what the weather/temps will be. As the discussions above show you could have 28F or "sitting outside weather". You could have clear, fog, rain, or even a bit of snow. (BTW NeoP - I've seen snow flurries in SF several times - like mentioned there are many micro climates)

Most likely you will have low 40's to high 50's F, even possibly low 60's, during the day, and high 30's to low 50's at night. As you can see - that is quite a range.

>>But you should also realize that the temps I've given are for San Francisco itself. You can go out of the city 20 miles and it can be a LOT warmer (or even colder along the coast).<<

Not in December. Perhaps 5 degrees at the most unless there is something really unusual going on. Often. it will be warmer in he City. A wind or damp fog in The City can make it seem colder.

I was going to post the same thing Stu did -- those wild temperature swings are a creature of the heat, and apply in the summer, not the winter.
