I was in San Rafael, Corte Madera, and Larkspur (where Dirty Harry shot jumped on the bus and shot Scorpio (the trestle and quarry are gone)) yesterday. I was at least the mid 90s there. When we got to Richmond, ~6 miles away and across the bridge, it was 69 degrees.
Today I checked and it was 68 in Richmond ion the Bay northwest of Oakland . At my house, 25 miles away, it was 98!
I driven through the Caldecott Tunnel in Oakland. It's located right where the big fire in 91 was. On the Oakland side I have seen peas soup fog and temps in the 60s. On the east side, 0.6 miles away, it is perfectly clear and in the 90s.
