What to Pack, What to Wear in August
August is one of San Francisco's driest months, so rain gear isn't needed, but a warm, hooded jacket will be welcome if you're out in the fog. Shorts may sound like a good idea, but you could end up with some pretty cold legs if you're in them on the wrong day.

Especially Fun in August
August is a good month to check out some of San Francisco's best beaches.
August is the final month of the season for the Stern Grove Festival. You can't beat the performers, the price (free) or the laid-back San Francisco ambiance at this outdoor summer concert series.
August is blue whale and humpback whale season around San Francisco. Find out how, when and where in the San Francisco Whale Watching Guide.
Major League Baseball season runs from March through early October and San Francisco has one of the prettiest stadiums around. If the San Francisco Giants are playing at home, watching a game is fun way to spend a few hours. We like afternoon games better than night because it's warmer.
Summer evening activities continue through August. Check them out in the guide to San Francisco Summer Nights
Averages and Reality
Use the weather averages to get an idea of what things may be like, but it might be different when you visit. A winter day could even be so warm you'll wish you packed your shorts.
Averages are helpful for planning ahead, but don't count on your trip being "average." Check the San Francisco weather forecast before you leave home.
