Monthly averages for temperature, precipitation, wind, and daylight from 1991 to 2020
Trace the annual climate pattern at Biosfera Val Müstair using representative point data from 1991 to 2020. Monthly tables provide structural insights into temperature fluctuations, precipitation rates, relative humidity, wind speed, and daylight hours at a standard elevation of nearly 2000 meters, distinct from daily weather or localized microclimate conditions.

Long-term thermal range and monthly precipitation rates across twelve representative coordinate records
Compare long-term temperature bounds, precipitation rates, humidity, wind, and daylight across the calendar year.

See two months side by side and how much they differ. Both use the same 1991–2020 climate normals and NASA POWER data point as the table above, so they show typical conditions, not a forecast.
