My favorite weather map for SF is PurpleAir: https://map.purpleair.com/environment-estimated-temerature-f...

There are thousands of sensors around the city. You can get a sense of shade-vs-sun temperatures by the spread of numbers you see (on cloudy days, the reported temperatures will be much closer together, while on sunny days, sensors in the sun will report elevated temperatures.)

You do need to make sure to disable indoor sensors, and keep in mind that some sensors are faulty. (I've seen some that have been reporting a constant temperature for years.)

This one is neat, I might actually use it.

I don't understand why it includes indoor sensors at all let alone by default. Why would I want to know the temperature inside some random building?

    Add location_type=0 to only get outdoor sensors

      or just click the buttons that accomplish the same thing. The point is someone at PurpleAir is asleep at the wheel if such an obvious default configuration isn't being set. If they can't get such a basic thing right, why do we trust anything else from them? "Anything else" specifically including "running their software on a raspberry pi inside my home network".

I use that and Mr. Chilly.

Mr. Chilly is one of those niche apps that sparks joy and reminds me of the early app days.
