I haven't seen the hills this green around the Bay Area which is like a scene you would normally see around the Pacific Northwest and England's countryside. The last winter brought a lot of rain (on top of the hail and snow) into the area making San Francisco look very lush and green. Very Seattle-like.
The fog didn't waste any time because the weather turns from rainy to foggy - at least during early morning and late afternoon and it depends on where you are in the city.
