Lake Annecy weather: air temperature, wind and rain

Compare water temperature with air temperature, humidity, wind speed, gusts, solar irradiance and precipitation. These are station observations, not weather forecasts. A reading describes the measurement location and does not necessarily represent every beach around Lake Annecy. The dashboard map shows available sensors and webcams.

Lake Annecy climate and seasonal changes

Weather describes current conditions; climate requires observations over long periods. This site's history starts on 8 September 2026. It supports comparisons within the available observations, but cannot establish climate normals or a warming trend. Missing periods are left empty rather than filled with invented measurements.

For long-term context, see the Grand Annecy climate assessment (French). The Annecy sun and daylight page (French) shows changing day length throughout the year.

Where do the measurements come from?

Readings come from the Requea station. Check the timestamp before interpreting a value; an older reading is identified when updates are delayed. The source provides point measurements rather than lake-wide averages.
