Twelve-month climatology profile based on long-term averages for a representative geographic coordinate
The Nosivolo River climate profile provides a systematic look at atmospheric conditions using NASA POWER measurements from 1991 to 2020. Grounded in a representative point at approximately 99.77 meters in elevation, the dataset tracks average maximum and minimum temperatures, daily precipitation rates, relative humidity, wind speed, and daylight hours. These monthly normals illustrate long-term patterns within the Atsinanana region rather than reflecting current weather, seasonal forecasts, or localized variations across the broader protected area landscape.

Analyze monthly average temperatures, daily precipitation rates, wind, humidity, and daylight duration.

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.
