HEAT & STORM ALERT: Extreme weather threat to voter turnout for local elections

Scorching temperatures and severe afternoon thunderstorms pose a potential risk to voter turnout in the 2026 local government elections across South Africa. The South African Weather Service (SAWS) has issued warnings as temperatures are expected to soar, with the Western and Northern Cape bracing for temperatures exceeding 36°C, while highs in the mid-30s are anticipated across central and northern regions, including the Free State, North West, Gauteng and Limpopo.

According to SAWS meteorologist Tokelo Chiloane, the heat will not be confined to the Cape region, as some areas in Limpopo and the Lowveld of Mpumalanga are also set to experience temperatures surpassing 36°C. Severe thunderstorms are forecasted for parts of Mpumalanga and north-western KwaZulu-Natal, with a 30% chance of showers and thunderstorms, yet these storms are anticipated to be severe.

Political analysts warn that these weather conditions could significantly impact voter participation. Historically, harsh weather has been known to discourage voters from heading to polling stations. Oscar van Heerden notes that political parties often encourage early voting to avoid stormy conditions, yet this tactic frequently proves ineffective as some voters defer their visits until crowds dwindle, only to be deterred when storms arrive.

Wayne Sussman emphasizes that vulnerable communities are particularly affected by extreme weather. He cites the 2016 elections in Nelson Mandela Bay, where torrential rains disproportionately suppressed turnout in impoverished areas. Middle-class voters could access their polling stations due to their own transport, while those who are poor and vulnerable were more concerned with clearing water and did not want to visit temporary voting sites.

Sussman also highlights that weather acts as a test of political motivation. Those with a strong commitment to their party are more likely to vote regardless of weather conditions, while those who are less invested may opt out if the weather poses a significant inconvenience. Ultimately, the weather's influence may very well determine the extent to which millions of registered voters participate in the local elections.
