Detailed atmospheric measurements and annual averages for a representative geographic coordinate.
The Marievale Bird Sanctuary climate profile presents consistent monthly averages for temperature, precipitation, humidity, wind speed, and daylight hours. Derived from NASA POWER data covering the 1991 to 2020 period, these measurements provide a standardized climatological record for one representative point at 1609 meters elevation. The record offers a systematic look at the annual atmospheric rhythm within this Gauteng wildlife reserve.

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.
