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. Unless otherwise mentioned, the information below is valid assuming you’re using version 5.1.8 or later of Breezy Weather.

By default, when you add a location manually, Breezy Weather will auto-suggest your national weather source if we have support for it, and combine it with other secondary weather sources for missing features.

When we don’t have support for your national weather source, we suggest Open-Meteo which 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, and usually more accurate for many countries, however still lacks a few features (station observations, alerts, reverse geocoding), which is why AccuWeather is also suggested for alerts and normals for some countries.

For United States of America, the Forecast Advisor website has temperature and precipitation 1-3 days accuracy comparison by city of the following sources: AccuWeather, NWS, Open-Meteo, OpenWeather and Pirate Weather.

Below, you can find details about the support and implementation status for features on each weather source.
