Twelve-month study of long-term average temperature, humidity, wind, and daylight cycles
Examine the representative climatology for Mousa, Shetland, based on NASA POWER measurements collected from 1991 to 2020. This data details monthly changes in mean temperature, precipitation rates, relative humidity, wind velocity, and daylight hours at a single reference point. These long-term averages provide an objective view of the local atmospheric rhythm, distinct from current weather conditions or short-term forecasts.
