The other other point is that the rain isn't always constant. Often the weather report in the evening predicts morning rain, and I have a dry ride in to work. As bigbenaugust implies, there are at least three microclimates in the bay area.
Personally, I equip with fenders and rain cape (admitedly most prefer rain suit) and bike in all but a downpour. If there is a downpour on the way home, oh well, I get home mostly dry and change clothes.
