I incorporated OpenMeteo into a project recently and got frustrated with their aggressive rate limiting. If in the US, weather dot gov has an excellent, free API. Or, OpenWeatherAPI which works internationally and has support for more things that weather dot gov does not. OpenWeatherAPI will also synthetically provide weather data based on their models if there is missing station data

Which one? They seem to do 600 calls / min, 5.000 calls / hour, 10.000 calls / day, 300.000 calls / month, how many times do you need to look up the weather for personal use? Fine, maybe you want 3 different locations, you can still call each of those sufficiently with those rate limits, no?

a redis geospatial index + redis distribution locks you can build a performant cache layer that is consumed by a ton of people and stay well under that rate limit.... the weather data only updates every 5 minutes too, so you can use that for your cache ttl.

I have to sample multiple lat/lon across the world all at once

For what purpose? And multiple times per hour for each of those? Sounds like not a personal project already.

It’s for a hobbyist project and non commercial use.

Right, but less "I want to know what the weather is locally and maybe in my summer house" and more "I'm curious about sampling global weather/temperatures", right? I don't think the intention of the API is for the latter, but more for the former.

Using your own weather station is another option
