Long-term atmospheric patterns including humidity, wind, and daylight duration metrics
Sankarani River climate profiles provide twelve-month averages for temperature, precipitation, and wind based on NASA POWER data from 1991 to 2020. These measurements represent the long-term climatology at a fixed coordinate within the protected area. Each monthly entry captures average daily metrics, including maximum and minimum temperature ranges, humidity levels, and daylight hours, to support detailed analysis of annual environmental conditions.

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.
