The Swiss Alps (this page centers on Zermatt, beneath the Matterhorn) see real altitude-driven weather — valley conditions can be calm and clear while ridge-height wind is a different story entirely, and afternoon cloud buildup around peaks is common even on an otherwise good-forecast day. Wind by altitude is the metric to actually watch here.

Swiss Alps: best time to fly
These figures summarise three years of hourly weather data for Swiss Alps (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: May, June, and August, when on average 72% of daylight hours had wind and gusts within the Good limits.
- Windiest month: January, with wind or gusts beyond the limits in 48% 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: June, 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. Use these figures to choose a season and time of day, and the live forecast above to decide on the day. See how UAV Meteo rates conditions and our data sources.
