Weather sources

This is a user-end guide to weather sources available in Breezy Weather. If you are a developer looking to add a new source in Breezy Weather, have a look at contribute.

AccuWeather is the most complete source, although you may not need so much completeness (not many people care about ceiling, for example).

Open-Meteo is the only free and open source weather source on this list, and probably also the most privacy-friendly. It is nearly as complete as AccuWeather, however lacks major features (short-term forecast accuracy, alerts, realtime precipitations and reverse geocoding).

Accuracy

When deciding about which source you want to use, accuracy of data is probably the most important criteria.

Here are some suggestions based on various criteria or testimonies (you can suggest others in GitHub discussions):

Additional sources are available to configure but requires an API key. You can find them at the bottom of this page.

• ¹ Bundled API key is often rate-limited. You can configure your own API key, however OpenWeather asks for credit card information even if you only want to use the free-tier.
• ² Some features may not be available everywhere.
• ³ Aggregated data from Beijing Meteorological Service, ColorfulClouds (Caiyun) and CNEMC

❌ means that it’s either not supported or doesn’t support longitude/latitude.

• ¹ Only supports NWS alerts, but has many duplicate issues, so not worth implementing
• ² Not restricted but currently only works in Europe
• ³ Works best in Europe at the moment
• ⁴ Implemented but it is not yet possible to change secondary normals source for a location from UI
