What causes microclimates in a city?

Question

I grew up right outside of San Francisco and was conditioned to dress in layers as the weather is so dependent on where in the city you are. I never understood why though. Thanks!

Answer 1

It’s a few degrees warmer in the city thanks to all of the hard surfaces and lack of shade, but you need to dress in layers regardless because the weather changes throughout the day. It’s much more a function of weather and going indoors vs outdoors than it is the few degree difference between the city and the suburbs.
