TIMELINE
This is a weather/operational assessment based on available forecast data and your selected drone profile — not airspace clearance or aviation authorization. Always check NOTAMs, local regulations, and your drone's own manual before flying.
Conditions last updated 14:15 local time
Chamonix sits in a narrow alpine valley directly beneath Mont Blanc, and that terrain drives strong katabatic (downslope) winds as cold air drains off the glaciers, particularly in the evening. Wind by altitude is genuinely useful here, since conditions at valley floor and near the ridgelines can be very different flights.

These figures summarise three years of hourly weather data for Chamonix (2023–2025). Only daylight hours are counted, and wind is rated against the standard drone profile: Good means wind up to 18 km/h and gusts up to 28 km/h; Not suitable means wind above 25 km/h or gusts above 35 km/h.
- Most flyable months: February, May, and September, when on average 66% of daylight hours had wind and gusts within the Good limits.
- Windiest month: January, with wind or gusts beyond the limits in 40% of daylight hours.
- Time of day: the average wind changes little during the day here, so the day's forecast matters more than the hour you choose.
- Rainiest month: May, when rain falls on the most days.

ERA5 describes the average over a grid cell about 30 km wide, so local effects are smoothed out: cliffs, valleys, coasts and buildings can be windier or calmer than shown.
