You might think "Is San Francisco cold in July?" is an absurd question. July is the middle of summer and you've seen all those movies, tv shows, and videos of people playing at the beach in brilliant sunshine. In truth, it's not a silly question at all. Just ask any of the hordes of tourists who come to San Francisco with nothing but shorts and tank tops and end up shivering on a foggy day in front of a souvenir shop, looking for the warmest layers they can afford.
You should definitely read the section about weather to get the full picture when you're trying to decide whether July is a good time to go to San Francisco.

San Francisco Weather 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 the whole state is sunny were filmed in Los Angeles, weren't they?
For the same reasons, July isn't the best month to go to the beach in San Francisco. It's likely to be gray and foggy, and the water is frigid.
- Average High Temperature: 69 F (21 C)
- Average Low Temperature: 55 F (13 C)
- Water Temperature: 56 F (14 C)
- Rain: 0.04 inches (.01 cm)
- Rainfall: 0.3 days
- Daylight: 14 hours
- Sunshine: 10 hours
- Humidity: 69 %
- UV Index: 9
If you want to compare July weather to other months, check the guide to San Francisco weather and climate. Before you make your final plans and pack that suitcase, check the San Francisco weather forecast a few days in advance of your trip.
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.
What to Pack
Many visitors find it hard to believe, but July is not the month 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 raincoat, but the fog can make you damp and miserable, so a hooded jacket is a good idea.
Pack sunscreen and sunglasses. When the UV Index (amount of skin-damaging radiation) exceeds 6 to 7, you need both skin and eye protection.
