Voters across South Africa should plan around dangerous heat and possible afternoon storms on 4 November 2026, with the South African Weather Service warning of very hot conditions in the west and severe thunderstorms in parts of the eastern provinces.
The weather could complicate travel to voting stations, particularly for people who rely on walking or public transport, and may affect participation if storms arrive while queues are forming. Conditions are expected to vary sharply across the country, with temperatures reaching the high 30s and low 40s in parts of the Western Cape and Northern Cape, while eastern areas face the possibility of heavy rain, hail and intense lightning.
Heat concentrated in western provinces
SAWS has warned of very hot to extremely hot weather in the Western Cape and Northern Cape. The central and northern interior is also expected to be warm, with temperatures in the mid-30s forecast for the Free State, North West, Gauteng and Limpopo.
Some parts of Limpopo and Mpumalanga’s Lowveld could reach 36°C. These conditions may make it difficult for people waiting outdoors, especially during the warmer part of the day. Voters are advised to plan their journey carefully, carry drinking water and seek shade where possible while waiting to cast their ballots.
| Area | Expected weather risk |
|---|---|
| Western Cape and Northern Cape | Very hot to extremely hot conditions, with temperatures in the high 30s and low 40s in places |
| Free State, North West and Gauteng | Temperatures in the mid-30s, with possible showers and storms in some areas |
| Limpopo and the Mpumalanga Lowveld | Warm to hot conditions, reaching about 36°C in places |
| Mpumalanga and north-western KwaZulu-Natal | Risk of severe thunderstorms, heavy rain, hail, lightning and local flooding |
Storm threat in the east
A yellow level 4 warning has been issued for severe thunderstorms in parts of Mpumalanga and north-western KwaZulu-Natal. The warning indicates a significant possibility of intense downpours, rapid localised flooding, hail, strong lightning activity and wind gusts powerful enough to damage infrastructure, including power lines.
SAWS has also issued yellow level 2 and level 4 warnings covering parts of Limpopo, Mpumalanga and KwaZulu-Natal for the afternoon. Gauteng has a 30% chance of showers and thunderstorms, and some of those storms could become severe.
People travelling to voting stations should monitor updated forecasts before leaving and allow additional time if rain develops. Motorists should not attempt to cross flooded roads or low-lying areas, while pedestrians should move indoors or into a sturdy shelter when lightning or severe wind begins. Queues should be managed with the heat in mind, particularly in exposed areas.
Possible effect on voter participation
Political analyst Oscar van Heerden said severe weather could influence participation. He noted that political parties commonly encourage supporters to vote earlier when afternoon thunderstorms are expected, although some voters delay their arrival in the hope of finding shorter queues later in the day.
Analyst Wayne Sussman said poor weather could place a heavier burden on vulnerable communities. He referred to heavy rain during the 2016 elections in Nelson Mandela Bay, where poorer areas experienced a disproportionate effect on turnout.
The immediate priority for voters is to avoid the hottest periods where possible, remain alert to local storm warnings and take shelter promptly if conditions deteriorate. Weather conditions may differ considerably between provinces, so people should check the latest SAWS information before setting out and follow any safety instructions issued for their area.
- Plan trips to voting stations before the hottest part of the day where possible.
- Carry water and protect yourself from prolonged sun exposure.
- During thunderstorms, avoid open ground, exposed trees and flooded routes.
- Allow extra travel time if heavy rain, hail or lightning develops.
