Traveller notes on Sacramento in August
Notes from nearby San Francisco (121 km away)
Sacramento doesn't have its own notes for August yet — these are about San Francisco, close enough to share the season.
I recently learned that "The coldest winter I experienced was a [summer/August... sources differ] spent in San Francisco" is apocryphal Mark Twain, but having just experienced San Francisco in August, I'm going to pretend I don't have that info. Brr! That fog does not play.
Other months in Sacramento
California's forum treats April as good weather statewide, with inland Central Valley cities like Sacramento running warmer than the coast by this point in spring. Regulars' standard advice for April travel anywhere in the state: pack layers, since mornings and evenings still run noticeably cooler than the afternoon.
