I’ve used https://open-meteo.com/ before and I think it’s the same type of open data being exposed.

These types of projects are great for stuff like home automation. I’m using to to improve my predictions for power generation (PV) and consumption (heat pump). Planning to is ergst to optimize home battery charging in the future.

Hi, creator of open-meteo.com here! I am using a more wide range of weather models to better cover Europe, Northern Africa and Asia. North America is covered as well with GFS+HRRR and even weather models from the Canadian weather service.

In contrast to pirate weather, I am using compressed local files to more easily run API nodes, without getting a huge AWS bill. Compression is especially important for large historical weather datasets like ERA5 or the 10 km version ERA5-Land.

Let me know if you have any questions!

open-meteo.com looks awesome. I've been messing around writing a snow forecast app for skiing/snowboarding for a while now and the main thing I'm missing is historical snowfall data. Do these data sources exist in a machine readable format and I've just not been able to find them? If so, would you ever consider adding precip + kind of precip to your historical API?

[meteo-jeff]

Snowfall is already available in the historical weather API. Because the resolution is fairly limited for long term weather reanalysis data, snow analysis for single mountains slopes/peaks may not be that accurate.

If you only want to analyse the weeks to get the date of last snowfall and how much power might be there, use the forecast API and the "past_days" parameter to get a continuous time-series of past high-resolution weather forecasts.

I've done exactly that! https://www.youtube.com/watch?v=oFSQYK20YUU&list=PLT7ckgz8vc...

I've got a bunch of moving parts in my system, including realtime (5-minutely) energy pricing. If it looks like it's going to be cloudy tomorrow I put my thumb on the scales to make it more likely that my system will buy power from the grid to top off the battery so I can ride through any price spikes.

I don't have the stats chops to determine whether I'm actually saving any money with this approach, but it sure is a lot of fun.
