Long term climate normals covering temperature, precipitation, humidity, and daylight patterns
Annual atmospheric cycles for Réserve naturelle nationale de la haute vallée du Vénéon are derived from representative coordinate measurements between 1991 and 2020. Detailed monthly normals provide consistent benchmarks for average temperatures, daily precipitation rates, wind speeds, and daylight duration. Measurements offer a stationary view of local climatology independent of current weather patterns or short term fluctuations, grounded in robust meteorological observations at elevation.

Long-term monthly averages for minimum, mean, and maximum temperatures alongside daily precipitation rates across the year.
Twelve-month comparison of long-term temperature bounds, precipitation rates, humidity, wind, and calculated 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.
