Weather In A San Francisco Summer

Summer is here and it’s time for weird weather. San Francisco has four distinct microclimates, the fog belt [where I live], the banana belt [Mission area and everything East], Wind belt [downtown which is made possible by all the high rises funneling the air and the Marine Belt [just around the Golden Gate Bridge and extending down to the Embarcadero.

I had the chance to travel to the Potrero District [banana belt] this morning. I left the house to overcast foggy 55° weather and hopped in my car and started to drive East. Suddenly I noticed it starting to get brighter. I had to pull out my sunglasses and when I arrived out on Rhode Island street it was perfect blue skies and sunny. As I opened the door to my car I was hit by 73° according to my iPhone. That’s almost a 20° difference within a half hour’s drive.

There are even sub-microclimates, but for people who move to San Francisco they have to learn the city to understand it best. The first thing you need to learn is layers. In the Sunset District my Dad would go out in the backyard on weekends in the morning to work the garden. He’d have a tank top, t-shirt, sweatshirt and jacket on. As the day wore on the clothes would soon start to come off. Then around 3pm he’d have to start putting them all back on again.

While the Sunset has a bit of temperament about it’s weather, it’s not constantly foggy. We’re actually getting more sunny days than we used to, but I remember my brief stint living in the mission and I don’t think I owned a single long sleeved shirt unless it was for work downtown. Sure it will get overcast upon occasion in the Mission and Potrero, but you never see fog like you do in the outer Sunset and Richmond Districts. Now at least I know if I’m in need of some sun on a cold foggy day in San Francisco all I have to do is head East for a few miles.
