Long term representative averages covering twelve months of atmospheric observations
Explore the multi decadal climate profile for Oostvaardersplassen based on NASA POWER measurements collected between 1991 and 2020. Data includes mean, minimum, and maximum temperature ranges, average daily precipitation rates, relative humidity, wind velocity, and daylight duration at a representative coordinate. This record provides a consistent baseline for understanding annual atmospheric rhythms within the nature reserve.

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.
