Twelve-month climatology profile showing long-term temperature, humidity, and rainfall patterns.
This climate profile displays long-term atmospheric patterns for Chayu Nain Communal Reserve based on NASA POWER measurements from 1991 to 2020. Data reflects monthly averages for mean temperature, daily precipitation, relative humidity, wind speed, and daylight hours at a single representative coordinate. These statistics provide a consistent look at environmental norms, distinguishing long-term climatology from short-term weather fluctuations.

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.
