#2My 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.)

#3How does this compare to https://www.wunderground.com ?
Is that the source of the data?

#4Is it possible to get individual sensor data via this API?

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?

#7It seems weird to me that there's no human readable version on the webpage?
Usually what I want the weather for is to choose what to wear, not to put in a bash script or an LLM or something.

Purple Air is the primary source but it's open source and you could try other providers https://github.com/solo-founders/sf-microclimates

#9This happens in Portland as well! Can this be adapted/updated to work here?

I made this primarily to use inside Claude Code in terminal but maybe I'll make a little demo on the website if you put in an SF zip code.
