Long-term annual averages for temperature, precipitation, humidity, wind, and daylight hours
Ilse Nature Reserve in North Rhine-Westphalia provides a consistent climatology profile based on NASA POWER measurements collected from 1991 to 2020. This data details representative monthly averages for temperature, precipitation rates, relative humidity, wind speed, and daylight duration. The records establish an annual rhythm for the protected area, providing a standard reference for atmospheric conditions across the calendar year.
