Joburg’s rain season has arrived, offering relief from the dry winter but creating new concerns about flooding in a city still recovering from storms earlier this year.
The South African Weather Service (SAWS) says it’s unlikely Joburg will be spared from intense summer downpours that are forecast for Gauteng.
“The latest seasonal outlook predicts wetter-than-usual conditions stretching from spring into early summer,” SAWS forecaster Lehlogonolo Thobela has said.
“This trend is being driven partly by a developing La Niña weather pattern that typically brings higher rainfall to the country’s interior.”
Joburg still reeling from floods
Thobela added that the wet conditions could extend well into early 2026, with the peak storm period expected between November and February, when flash floods and severe thunderstorms are most common.
For many Joburgers, the warning may stir up fresh memories of March’s downpours that flooded roads, swept away informal homes and left several low-lying Joburg neighbourhoods – including Alexandra, Soweto and Diepsloot – waterlogged for days.
Sections of the M1 highway were submerged and emergency crews had to rescue motorists that were trapped in rising water.
Poor drainage, blocked stormwater channels and rapid urban growth have made even moderate storms increasingly disruptive.
SAWS says it has moderate to high confidence in the latest forecast, and is urging residents to prepare early rather than wait for emergency alerts.
Is the City prepared?
SAWS has offered the public a series of safety tips ahead of the summer rains, advising Joburg residents to:
- Clear gutters and stormwater channels
- Secure valuables and electronics above ground level
- Ensure households have an emergency plan in place
The agency has also urged Joburgers to avoid rain-flooded roads.
“Do not attempt to drive or walk through flooded roads or underpasses as most flood-related incidents happen in vehicles,” SAWS added.
The Gauteng Department of Cooperative Governance and Traditional Affairs (COGTA) meanwhile says it has strengthened its flood-readiness plans.
“Experience has highlighted the importance of proactive disaster preparedness,” said the MEC for COGTA, Mzi Khumalo.
“This season, the province is prioritising stronger community education and awareness programmes to ensure people understand impact-based alerts.”
Provincial government is also working to reduce the risks faced by Joburg communities living along riverbanks and floodplains.
