Inspect the full calendar at a sampled 68.56 m lake coordinate
Lake Sibaya records a sampled mean temperature of 18.77 °C in July and 25.85 °C in February. Daily precipitation averages 0.64 mm in June and 4.54 mm in January, while wind speed measures 4.45 m/s in May and 5.77 m/s in October. NASA POWER’s 1991–2020 monthly series also covers humidity and daylight at one 68.56 m point; it is not live weather, a forecast, or proof of identical conditions across the protected area.

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.
