Best time to visit iSimangaliso Wetland Park

iSimangaliso's calendar is set by the sea more than by the rains. Turtles nest on the northern beaches from November to March and humpback whales pass from June to November, while the hippos and crocodiles of the St Lucia estuary are there every month of the year.

If you only want the answer

June to September. August averages 26 mm against 133 mm in February. That gap decides what you see: spread out across the park in the wet, gathered at whatever water is left in the dry.

Prime Dry but hot Shoulder Green season Bar height is average rainfall, the figure above it is the daytime high. The $ signs show what a night in the park runs in that period.

The year, season by season

The periods below are how this park actually divides its year, with thirty-year climate averages against each month. Averages hide bad years: a dry January still happens, and so does a wet July.

Climate figures are Open-Meteo climate normals, 1991 to 2020, measured at -27.675, 32.5. Prime, shoulder and green are worked out against this park's own year, not a fixed threshold: the four months with the least rain, the four with the most, and the rest in between. Full charts on the weather page.

When is the best time to visit iSimangaliso?

It depends on what you came for. For whales and dry, mild weather on the Eastern Shores and in uMkhuze, go between June and September: the Open-Meteo normals give 23.0 to 25.2°C by day and 15.7 to 18.2°C at night, and fewer than five rain days a month. For turtles, go between November and February, and accept that it is hot, humid and wetter. For both together, mid-November is the window.

The estuary cruise, the hippos and the crocodiles do not depend on the season. Neither does diving at Sodwana, where Coral Divers gives water temperatures of 20 to 28°C. The climate figures here are Open-Meteo normals for 1991 to 2020 at a point near Sodwana; iSimangaliso publishes no climate data of its own.

Rate seasons and crowds

The state camps charge a higher rate in the South African holidays. Sugarloaf campsite in St Lucia lists its 2026/27 high seasons as 26 September to 10 October 2026, 11 December 2026 to 11 January 2027, 19 March to 5 April 2027 and 23 April to 3 May 2027. Under the last published Ezemvelo tariff (2023/24) a 4-bed Cape Vidal cabin went from R1,890 to R2,610 in high season; these state-camp prices are a floor, since iSimangaliso has run the camps since 1 March 2026 and has published no new tariff.

Private lodges vary the minimum stay more than the price. Thonga Beach Lodge charges one rate from 1 July 2026 to 30 April 2027 (from R6,840 per person sharing) but asks for three nights between 15 December and 15 January. Makakatana Bay Lodge drops from R10,880 to R9,250 per person in its winter season of 1 May to 30 June 2026. Coral Divers at Sodwana prices its tented and cabin beds in low, mid and high seasons for February 2026 to January 2027.

The Authority's own advice is that South African school holidays, Easter and the December period book out months ahead, particularly the cabins at Cape Vidal and Sodwana.

What to plan around

  • Turtles: nesting from late October or November to about January, hatchlings January to March. Kosi Forest Lodge sells turtle tracking only from 15 November to 15 January; Thonga Beach Lodge from November to February.
  • Whales: June to November, from the cliffs at Mission Rocks and Cape Vidal or with the licensed boat operator at St Lucia.
  • Game drives and hides: June to September, when the bush is thinner and the uMkhuze pans draw animals.
  • Waterbirds: summer, when the Kubube hide in uMkhuze is at its best.
  • Malaria: the northern sections carry a low risk from September to May (NaTHNaC), highest in the wet months from November to April; ask a travel clinic.
  • The estuary mouth opens and closes with the rain. It breached naturally on 10 January 2025 after closing in August 2024; check locally.
