South Africa remained in a settled weather pattern on 18 August 2026, with the SA Weather Service (SAWS) reporting no impact-based warnings, no fire danger warnings and no advisories anywhere in the country. The largely calm conditions follow a period of cooler weather and mark a second consecutive day without official alerts.
What to expect across the country
Central and eastern provinces will generally experience fine, dry conditions with temperatures ranging from cool to warm. Gauteng, Mpumalanga and Limpopo are all forecast to be fine and warm, while the North West is expected to stay fine and warm as well. The Free State should remain fine, with conditions described as cool to warm.
Coastal regions present the only notable departures from the settled picture. The Western Cape will see cloudier conditions along the coast, with a chance of light rain in the Overberg and Garden Route in the morning and generally cold to cool temperatures there; the northern West Coast is expected to be warm by comparison. In the Eastern Cape, the western half begins with morning fog then clears to fine, cool weather, while the eastern half also starts foggy in places south of the escarpment before clearing and turning cloudy along the coast by evening, with a chance of light rain and showers on the Wild Coast.
KwaZulu‑Natal should see fog patches in the mornings and evenings, otherwise partly cloudy conditions from cool to warm, with isolated afternoon showers developing in the south‑east.
Sun safety remains important
Even though temperatures are milder in many regions, UV exposure is still a concern. SAWS indicated that parts of Gauteng, KwaZulu‑Natal and the Western Cape will carry a “high” to “very high” UVB sunburn index for the day. That means prolonged sun exposure can cause sunburn and increase skin damage risk.
- Take sun protection measures where the UV index is elevated: broad‑brimmed hats, sunscreen with broad‑spectrum protection, and sunglasses.
- Avoid prolonged mid‑day sun if you are outdoors for work or recreation.
- Keep an eye on children and people with fair skin, who burn more quickly under high UV conditions.
“Gauteng, KwaZulu‑Natal and the Western Cape all carry a ‘high’ to ‘very high’ UVB sunburn index today,” SAWS reported.
Morning fog and local variances — plan for reduced visibility
Fog patches are forecast in parts of the Northern Cape (western areas) in the morning as well as in coastal and escarpment‑adjacent districts of the Eastern Cape and KwaZulu‑Natal. Drivers should be prepared for brief periods of reduced visibility and drive cautiously where fog persists. No national transport or aviation advisories have been issued by SAWS, but localised fog can affect early‑morning travel.
| Province/Region | Primary forecast |
|---|---|
| Gauteng | Fine and warm |
| Mpumalanga | Fine and warm |
| Limpopo | Fine and warm |
| North West | Fine and warm |
| Free State | Fine, cool to warm |
| Northern Cape (west) | Morning fog, then fine, cool to warm |
| Western Cape (coast) | Cloudy, chance of light rain; cold to cool |
| Eastern Cape | Morning fog then clear; coastal cloud and chance of light rain in the east |
| KwaZulu‑Natal | Fog patches; partly cloudy, cool to warm; isolated south‑east showers late |
What this means for the week: the current settled spell could persist, offering a calm interlude after cooler conditions earlier in August. Forecasters and meteorologists will be monitoring any incoming fronts that could change the picture, but for now SAWS has not signalled any impact warnings nationwide.
Practical advice: if you plan outdoor activities, check local forecasts for morning fog and the UV index for your area. Carry sun protection even on milder days in provinces listed with elevated UV levels, and allow extra travel time where fog is reported.
