I've investigated and tried several (free) weather API's for my web app: https://uw.leftium.com . Open-Meteo looks pretty good! The only thing that seems to be missing for me is precipitation probability. The weathercode is sort of a proxy for this... I'm also interested in sunrise/sunset times; direct_radiation is kind of a proxy for this. Kudos for providing optional historical data with the same API call for the f…

does your app believe today is Thursday?

The app hit the DarkSky API free tier limit, so it's displaying mock data. There is a little message at the bottom. (Probably didn't snow two days ago, either...)

This API still works: https://uw.leftium.com/?api=openweather

Thanks for your suggestions! I will add precipitation probability as soon as I include 14-day ensemble weather models. Deterministic whether models usually do not offer this directly. I also really like the 2 days historical access :) At some point I would like to add more, but the storage requirements skyrocket quickly. Not only in space, but also disk IO to perform in-place updates. For air quality data I want to a…

Thank you for that. I run a home dashboard for my family that includes weather forecast from openweathermap.

This morning I decided to change the provider because the forecast is really unstable.

I will be glad to try yours and give feedback if you are interested. I am near Paris.

The host is netcup in Germany. I use regular KVMs. Yes, the amount of storage can be an issue, but I want to stay below 500GB of hot-data. One bottleneck is network traffic to copy updated files after each weather model update. My binary files are just plain Float16 files without an meta data. Logically they similar to 3D Zarr files. I know exactly which bytes I have to read and the kernel cache helps a look to keep…

Curious how much this would cost you to do from Google cloud storage or aws. Historical data access can be quite valuable (and something that might be a premium paid feature even).

For the VMs, the absolut minimum memory requirement is 16GB. The more, the better.

Otherwise it takes around 40 GB of disk space for every day of data. For an history of 100 days, 4000 GB are required. With compression I could save 50%, but have to invest a couple of days development time to make is work. You could calculate the AWS bill now ;-)

Data on cold storage is an option, but it also super slow....

Currently, I did not yet integrate all the high-resolution models that I want to. Coverage for Europe is great. In North America I will add high resolution NOAA models next.

Most likely I will keep only a limited subset of data as history, but on fast storage to make is accessible quickly

OK, I don't see the message here and my localization is correctly recognized so I didn't think it could be mock data. Snow two days ago? Let me think... probably not ;)

Ah, probably because you were viewing in landscape mode. The message only appears in portrait mode.

The app's main use case was for mobile, where you're likely to start in portrait orientation.

I'll have to make the landscape mode more usable, especially on desktop.

Wasn't DarkSky scheduled for closure by the end of the year?

You can check the Norwegian service Yr.no. https://www.yr.no/en/details/table/2-1263968/India/Tamil%20N... https://hjelp.yr.no/hc/en-us/articles/360001940793-Free-weat...

Thanks, this is one of the more accurate ones I've seen, it's still a bit off (3-4 degrees). Do you know where I can get historical data going back at least 10 years?
