Yearly patterns of temperature, precipitation, and wind based on 1991 to 2020 metrics
Gouritz Cluster Biosphere Reserve climate data provides a consistent twelve-month profile of atmospheric conditions at a representative coordinate in the Western Cape. These monthly averages cover temperature, humidity, and precipitation patterns recorded from 1991 to 2020. This resource details specific metrics including mean, minimum, and maximum temperatures; daily precipitation rates; wind speed; and daylight hours to support precise geographic understanding of this landscape.

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.
