A severe cold front swept across South Africa on 10 August 2026, triggering heavy snowfall, sub-zero temperatures, and the closure of multiple mountain passes throughout the Western Cape and surrounding provinces. The weather system, driven by a combination of an upper-air and surface low-pressure system, has caused significant disruptions to regional travel networks.
Infrastructure And Travel Disruptions
Western Cape Infrastructure MEC Tertuis Simmers confirmed on 10 August 2026 that the Swartberg Pass and the Molteno Pass have been closed to all traffic due to hazardous snowfall. These closures follow a broader trend of travel warnings across the Eastern Cape, KwaZulu-Natal, the Free State, and Mpumalanga, where major routes including sections of the N3 have been impacted.
The weather system is not out of the ordinary. The severe weather is linked to the combination of an upper-air and a surface weather system.
André Fourie, a forecaster at the South African Weather Service (SAWS), provided this assessment during a briefing on the cold front. The SAWS had previously issued an Orange Level 6 warning for disruptive snow, specifically targeting the Chris Hani District, Senqu, Elundini, and Matatiele municipalities in the Eastern Cape.
Public Safety And Official Response
The Government Communication and Information System (GCIS) released a formal statement on 10 August 2026 urging motorists to refrain from non-essential travel to high-risk areas. The government advised that the presence of black ice and strong winds creates extremely dangerous conditions for road users.
The Government Communication and Information System (GCIS) urged the public to avoid unnecessary travel to areas affected by heavy snowfall, ice, strong winds, flooding or other hazardous weather conditions.
The severity of this system marks one of the most significant winter weather disruptions of the season, impacting both commercial logistics and daily commuting patterns across the interior. While the system is described as a seasonal occurrence, the intensity of the snowfall has necessitated immediate intervention from provincial transport departments to prevent accidents. Our reporters are continuing to monitor updates from the Western Cape Department of Infrastructure regarding the reopening of these passes.
