Overall Weather Situation for 26–27 July 2026
The South African Weather Service predicts a predominantly fine and cool start to the period, with morning frost developing in many interior provinces. As the day progresses, temperatures will rise modestly, yielding comfortable daytime highs in most regions. Coastal zones, however, will experience increased cloud cover, isolated showers, and stronger winds, particularly along the south‑western and south‑eastern seabards. The overall pattern reflects a high‑pressure system over the interior driving clear skies, while a trough off the south‑coast brings moisture and windier conditions to the coastal fringe.
Impact-Based Yellow Level 1 Warning: Coastal Winds and Waves
A Yellow Level 1 warning has been issued for damaging coastal winds and waves between Cape Columbine and Cape Agulhas. In the SAWS colour‑coded system, yellow denotes a moderate risk that warrants caution and heightened awareness. Small vessels, personal watercraft, and beachfront activities may encounter difficult navigation and localized disruptions. Mariners are advised to secure equipment, monitor sea state updates, and consider postponing non‑essential trips until conditions improve. The warning is based on the likelihood of impact occurring, with Levels 2 and 6 representing high risk, Level 5 medium, and Levels 4 and 8 low.
Advisory for Tuesday and Wednesday: Snow and Cold in High‑Lying Areas
Very cold and wet weather, accompanied by snowfall, is expected over the high‑lying areas of the Eastern Cape, especially the Drakensberg range, as well as the southern parts of the Free State and the Lesotho border. Temperatures in these zones could dip well below freezing, creating hazardous travel conditions and increasing the risk of frostbite for exposed skin. Farmers are urged to shelter livestock, protect vulnerable crops, and ensure water supplies do not freeze. Residents should dress in layers, avoid unnecessary travel on mountain passes, and keep emergency kits handy in case of power outages or road closures.
Gauteng Province: Morning Frost, Fine and Cool
Gauteng will experience morning frost in places, otherwise fine and cool. Pretoria is forecast to reach a low of 5 °C and a high of 23 °C, Johannesburg 5 °C–20 °C, Vereeniging 4 °C–21 °C. The frost may form on grass and around sunrise, but sunshine will quickly raise temperatures, leading to pleasant daytime conditions. Light winds from the south are anticipated, and no significant precipitation is expected for the two‑day window.
Mpumalanga Province: Frost, Cool, Warm Lowveld
Morning frost is likely in places across Mpumalanga, with otherwise fine and cool conditions prevailing, except in the Lowveld where it will be warm. Mbombela expects temperatures between 7 °C and 25 °C, Ermelo 1 °C–20 °C, Emalahleni 4 °C–22 °C, Standerton –2 °C–21 °C, and Skukuza 5 °C–25 °C. The Lowveld’s higher temperatures will support outdoor activities, while frost‑prone areas may see icy surfaces early in the day that melt as the sun climbs.
Limpopo Province: Frost, Cool to Warm
Limpopo will also see morning frost in places, otherwise fine and cool to warm. Polokwane is forecast at 5 °C–22 °C, Phalaborwa 9 °C–26 °C, Tzaneen 7 °C–24 °C, Musina 8 °C–24 °C, Lephalale 8 °C–23 °C, and Mokopane 6 °C–22 °C. The northern parts of the province may enjoy warmer afternoons, suitable for agricultural work, while southern and higher‑lying localities could retain a chill into the late morning before the frost dissipates.
North West Province: Southern Frost, Otherwise Fine and Cool
In the North West, morning frost is expected in the southern regions, with the remainder of the province fine and cool. Klerksdorp anticipates 1 °C–22 °C, Potchefstroom 0 °C–21 °C, Mahikeng 6 °C–22 °C, Rustenburg 5 °C–23 °C, and Vryburg 3 °C–22 °C. The frost will likely be confined to grassy patches and vehicle windshields in the south, clearing by mid‑morning as temperatures rise under mostly sunny skies.
Free State Province: Frost, Cool Conditions
The Free State will experience morning frost in places, otherwise fine and cool. Bloemfontein is projected at 0 °C–21 °C, Welkom 1 °C–22 °C, and Bethlehem –3 °C–20 °C. The sub‑zero lows in Bethlehem highlight the potential for black ice on roads, especially early in the day. Residents should allow extra time for commuting and ensure vehicle antifreeze levels are adequate.
