MÉTÉO-FRANCE

In addition to the reliable weather sites for amateur astronomers (Astrosurf and Webastro in particular), this classic weather forecast is quite reliable at the local level when preparing an astronomical outing. As often with such services, it is important to focus on short-term forecasts (over a few hours) and not on several days, which are necessarily more random. Note that the platform, usable from a smartphone, is quite user-friendly. By comparing the forecasts obtained and calculated from different sources, it is often possible to ensure an accuracy of more than 80% on the ground.
