It 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.

Here you go: https://v0-weather-app-one-coral.vercel.app/

Made it in about 5 minutes with v0.

I use PurpleAir data for a lot of my home automations— I have a smart window vent and configure it to blow in/out depending on which side has the worse air.

(Thank you to those who maintain public sensors!)

I do notice that in my neighborhood (Noe Valley) a lot of the sensors are very incorrect or often offline. I've resorted to taking the median and throwing outliers away, but even this often doesn't work. This is the challenge of relying on crowdsourced data I suppose...

> I don't understand why it includes indoor sensors at all let alone by default. 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".

Because PurpleAir is not a weather service, they’re a sensor company.

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. It's an excellent iOS app: https://mr-chilly.com/ My goal was to do something similar as a Claude Code skill

I use Mr Chilly to demonstrate to non-SF folks how many microclimates SF (and the Bay Area has).

Only suggestion: separate Inner and Outer Sunset since there can be a massive difference between near Ocean Beach and near Irving/9th Ave in autumn (ie. SF's hottest season).

Edit: nevermind, just saw both inner_sunset and outer_sunset in /neighborhoods. I'd assumed it was merged based on the human readable list on the landing page. Thanks for the fun API!

I made a quick website from this API that shows all of the neighborhoods, searchable, sortable. https://v0-weather-app-one-coral.vercel.app/ Surprisingly, Lands End is the highest temp right now.

Inspired by this, I made a map: https://climate-map--jaredluxenberg1.replit.app/

Kinda neat!

Love the idea, but tried "japantown" which is mentioned in the README but doesn't exist in the app? https://microclimates.solofounders.com/sf-weather/japantown

thanks for catching this. just fixed.

note that I also have a system where if the temperature seems outlier compared to direct neighbors it averages the 3 nearest neighbors. this usually occurs in neighborhoods with a single sensor that can skew the results heavily at certain times of the day, etc.

thanks I will update the homepage to reflect this.

Can I suggest changing background color of the tiles between blue and red to indicate how warm each spot is? Would make it easier at a glance.
