SF WEATHER
The weather should be gorgeous! But San Francisco weather is as unpredictable as anywhere else in the Bay Area, known for it's temperamental fog. It can change from a summer day to a chilly afternoon and evening, so you should plan on having a light shawl, sweater, or jacket with you wherever and whenever, but especially on Friday night. In our experience in late August, it's typically 65 - 75 during the day and 55 - 65 after the sun goes down.

GLEN ELLEN + SONOMA WEATHER
The weather should be summery in Sonoma, but the weather in the Sonoma Valley is only marginally more predictable than San Francisco. The further east you go (away from the bay and the fog), the more reliable it gets. Even in Sonoma, it's best to carry a a sweather or jacket with you. In late August, it's typically 75 -85 during the day and 60 - 70 after the sun goes down.
