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.

This was directly inspired by Mr Chilly which was designed by my friend Anna Bleker.
Surprisingly, Lands End is the highest temp right now.

An interesting problem with self-reported temperature is that people just put their outdoor sensors inside for some reason or near an ambient heat source; also in neighborhoods with tall buildings, it's a bit colder higher up, so the balcony readers are a bit off from sidewalk temperature, it is interesting to see though that one block from another is super different in temp, is it because it's actually different or is there something heating/cooling the sensor off randomly

It's an excellent iOS app: https://mr-chilly.com/
My goal was to do something similar as a Claude Code skill
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.
Made it in about 5 minutes with v0.

Is that the source of the data?
You should use Purple Air if you want to make it more focused https://www2.purpleair.com/
