Month by month
iSimangaliso in September

If you only want the answer
A strong month for whales and game drives, with 43 mm of rain on about 5 days, days of 25.2°C and nights of 18.2°C. Book ahead for the last week, when the school holiday begins.
September weather: warming up
The Open-Meteo normals give 43 mm of rain over about 5 days, a day high of 25.2°C and a night low of 18.2°C. It is the last month of the dry window that runs from June, and the bush is at its thinnest for game viewing in uMkhuze and on the lake shores.
Whales before the turtles
Humpbacks are still passing, and the boat trip from St Lucia with the licensed whale-watching operator runs through the season. Turtles have not yet started; the monitors go out on the beaches in October.
Spring high season from 26 September
The South African school holiday runs from late September into early October, and Sugarloaf campsite's high season runs from 26 September to 10 October 2026. Under the last published Ezemvelo tariff (2023/24), the Cape Vidal campsite went from R340 to R1,000 a night in high season with a minimum of four people.
