After several unusual days last week in the high 80s and low 90s, the fog came back with a vengeance. San Francisco should be where that white, billowing, cloud-like substance is.
Above the fog, at Mt. Tam State Park (where this picture was taken), it was still surprisingly at least 90 degrees. Back in the fog, (where we live) it was windy, misty, and in the low 50s.
