Year-round analysis of temperature, precipitation, humidity, wind, and daily sunlight
Monthly climate averages for Maduru Oya National Park provide a twelve-month record of atmospheric conditions. Derived from NASA POWER data between 1991 and 2020 at a single representative coordinate, these values track temperature, daily precipitation, relative humidity, wind speed, and daylight hours. The data illustrates long-term climatological trends within the Eastern Province landscape, distinguishing historical norms from current weather or forecasts.
