I lived in SF from 1989 to 2006. In the summer, downtown was usually sunny during the day while sunset and richmond were socked in. Fog moved further in towards the afternoon/evening. I lived in the sunset and richmond the whole time and didn't see any change. In 1989 I sometimes didn't see the sun for weeks and 2006 still didn't see the sun for weeks, in those districts. Maybe something has changed in the last 15 years?
