Microclimates

Well, from before sunrise today we had clear skies. The high today was 65, with a crystal blue sky, bright sun and light breeze. However, the gray clouds were doing their best to peak over the hills a few miles to our west. If I had gotten in the car and headed west on Hwy 4, within 10 miles I would have been looking at gray skies and temps struggling to climb out of the 50s.

The meteorologists talk about the bay area microclimates. A combination of the chilly Pacific on the west, the San Joaquin Valley on the east and lots of hills and coastal mountains woven throughout the entire bay area, the temps can vary greatly in just the space of a few miles.

One day this summer it was over 100 in Antioch, but only in the 50s at Point Reyes. We needed jackets as we hiked around in the chilly ocean breeze. When we got home after dark, it was still in the 80s in Antioch.

Today there wasn't much temperature variation... 65 here and upper 50s in SF. And SF doesn't vary too much year round, with a few days of exceptions. In the summer SF will be one of the coolest parts of the Bay Area, usually in the 50s or 60s. In the winter SF will be one of the warmer parts of the Bay area, usually in the 50s or 60s. This winter when we get down in the 40s or 30s, we can go to the coast to warm up instead of to cool off.

Well, more than enough of that. It's supposed to be beautiful and in the 70s this weekend. And a north then northeast wind will wash pretty much all those clouds away from all the hills, valleys and beaches. Enjoy your very own climate, "micro" or not!

I guess that is one of the main reasons I love San Francisco so much - the climate. When we were there in June, my family wore jackets while I was enjoying short sleeves! My kind of weather.
