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):

Country/Continent	Main source	Air quality	Pollen	Minutely	Alerts
Europe			Open-Meteo
United States	Forecast Advisor
France	Météo-France		Open-Meteo	Météo-France	Météo-France
Norway	MET Norway	MET Norway	Open-Meteo	MET Norway

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

Combinable sources

From v4.5.0, you can combine your main weather source with other sources:

Sources	Open-Meteo	AccuWeather	MET Norway	OpenWeather	Pirate Weather	Météo-France	ATMO AURA
Air quality	✅	❌	Norway	✅	❌	❌	France (AURA)
Allergens	✅²	❌	❌	❌	❌	❌	❌
Alerts	❌	✅	❌	✅	✅	France	❌
Minutely	❌	✅	Nordic area	✅	✅	France	❌

❌ 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
