What to Expect from San Francisco in July
By July, San Francisco's typical weather pattern includes lots of fog and on the average, you'll encounter fewer days of sunshine than in the spring or fall. That fog is wet and the winds that accompany it make it all feel much cooler than the thermometer reading might imply.
"Isn't this California?" you may ask. Of course it is, but think about it - all those television shows and movies that gave you the idea that that whole state is sunny were filmed in Los Angeles, weren't they?
For the same reasons, July isn't the best of months to go to the beach in San Francisco. It's likely to be gray and foggy, and the water is frigid.

What to Pack, What to Wear in July
Many visitors find it hard to believe, but July is not the months for shorts and tank tops in San Francisco. Cold fog and breezes can easily make Fourth of July night can feel colder than New Year's Eve.
To watch San Francisco's Fourth of July fireworks, I wear warm, full-length pants and take 3 to 4 layers of long-sleeved shirts and/or sweatshirts. If you aren't prepared for it with proper clothing, you will most likely be improving the local economy by purchasing warmer clothes from a street vendor. Or heading for a warmer spot before the fireworks start.
Foggy, gray skies often make visitors from other areas think it's going to rain, but July is one of the driest months. You're not likely to need an umbrella or rain coat, but the fog can make you damp and miserable, so a hooded jacket is a good idea.

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.
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.
