Suggestion moved from Discord By FlyingVince72

Would be nice and helpfull to have a meteo layer on the map so that it is easy to focus on regions where the weather is good, or bad for those looking for such conditions 🙂 I think this layer does not necessarily have to be in real time, but a hourly refresh for example should be enough. One suggestion though which would be to have a filter there to select between low-air and high-air conditions or even better it could be a slider to define your max cruise altitude and then you will see the weather conditions up to that altitude.

Hello. I found this but don't know if it will include some solution... https://rapidapi.com/blog/access-global-weather-data-with-these-weather-apis/

Most of the time free part of these API's allow a certain number of request (up to 500-1000 request per day) but I don't know how it works exactly, if we speak about requests from your website (server) or from the user side (client). We only need here current weather (cloud layer), no historical data, no forecast so I suppose it should be possible to get this somewhere for free otherwise it 's shame. I often use the site metar-taf.com which shows that kind of cloud layer, and for free. So I suppose they've found the solution 🙂

Found something when digging around unrelated things. Not too sure how useful this will be (as the request appears to be for a WXR-type thing), however I don't see a mention of this service in the rapidapi article from the request, so I'll drop it in - maybe it'll be useful some day, even if for something else. Open-Meteo Headline features: Historic, FCST and current WX data, Open-Source, good data resolution, free non-commercial API access with no registration/key required, up to 10K (yes, ten thousand) calls per day (but it's not a strict cap, allegedly).

I intend to ask some others, when pertinent, where they get the data from for their WXR overlays...

Interesting indeed. One thing is the data, second is to get the data visualized in the Leaflet map provider I use 😅 Though I'll keep this one in mind for the future.

I said I would ask around, and so I did. They use RainViewer. Windy[dot]com allegedly also uses RainViewer for the "Weather radar" view, so it should be pretty decent. The RainViewer APIs respect privacy, they say, and are free to use, with an asterisk. And by that I mean the Weather Radar Database API is labeled as Patrons only. The two other APIs (or three, if you include the Legacy API) are free with no strings attached. When you look at their Live Weather Map with the "Coverage" setting on, you'll see that it's not exactly global coverage, but it's better than nothing. The tiles are served as pngs it seems, with JSON for information on how everything goes together and things like that. In the API Examples page they link a Leaflet plugin that can be used for showing their API, so with that it might not be too horrible to implement on W2F.
