Weather in September

Hi all

We%26#39;ll be visiting San Francisco for the first time in the last week of September. I wonder if you could tell me what kind of weather we should expect? We%26#39;re considering a hotel with an outdoor pool but I%26#39;m wondering whether it will be hot/sunny enough for that to be worthwhile.

Thanks in advance for your advice!

I know people that swim everyday without heated pools; they swim in the Bay! The hotels w/outdoor heated pools will be fine for you because it%26#39;s rather mild if you swim during the day when there%26#39;s sun. It is just not going to be tropical heat.
