2026 El Niño Update: South Africans In For Brutal Drought
- AccuWeather forecasters say the 2026 El Niño is strengthening rapidly and could surpass any event recorded since at least 1950
- Global sea surface temperatures in July 2026 hit record levels, sitting 2.1 degrees Celsius above the long-term average
- South Africa and southern Africa could face significant shifts in rainfall and temperature patterns as the pattern intensifies

The 2026 El Niño is shaping up to be one of the most powerful climate events in living memory, and forecasters say southern Africa should be paying close attention.
AccuWeather, an American weather forecasting service, published a detailed analysis on 20 August 2026 warning that the current El Niño could rival or surpass every event on record going back to 1850. That is a significant statement for a region like South Africa, which has a complicated and sometimes devastating history with the climate pattern.
What the data is showing
El Niño happens when ocean temperatures near the equator in the eastern and central Pacific rise well above their historical average for a sustained period. Those warmer waters then reshape atmospheric conditions, shifting rainfall, temperatures and storm tracks across the globe.

The numbers behind the 2026 event are striking. NOAA data analysed by AccuWeather shows a forecast mean of 2.66 on the RONI index, which would be the highest ever recorded. The previous record was 2.40, set between November 1982 and February 1983. In July alone, global sea surface temperatures surpassed record levels set during the 2023 marine heat wave, sitting 2.1 degrees Celsius above the long-term average.

In the report, AccuWeather Lead Long-Range Meteorologist Paul Pastelok noted that whether the event technically breaks records matters less than what it will do to weather systems. “It really does not matter whether this is a record or Very Strong El Niño. It is about the impacts,” he said.
What it could mean for Southern Africa
For South Africa, El Niño is historically linked to below-normal rainfall across large parts of the country, particularly the interior and eastern regions. Drought conditions, reduced crop yields and pressure on water supplies are among the most familiar consequences.
The 2015-16 El Niño, one of the strongest before this current event, triggered one of the worst droughts South Africa had experienced in decades, with severe impacts felt across Limpopo, KwaZulu-Natal and the Free State.
With the 2026 edition potentially exceeding that benchmark, concerns around water security, agriculture and food prices are already relevant. AccuWeather’s analysis also points to an active pattern of marine heat waves in separate parts of the Pacific, which could interact with El Niño and alter storm tracks in ways that differ from previous events.
AccuWeather has said it will release a detailed long-range winter forecast in October 2026, when meteorologists expect a clearer picture of how the developing pattern will affect rainfall, temperatures and storm behaviour heading into the Southern Hemisphere summer, the season that matters most for South Africa’s rainfall regions.
