[SYDNEY] Australia’s weather bureau warned on Tuesday (Jun 16) that an El Nino weather pattern has formed in the tropical Pacific Ocean, and could intensify in the second half of 2026 to become one of the strongest in seven decades.
Forecasters expect the stronger weather event to bring excessive rainfall to the Americas and create hot, dry conditions in Asia, where crop planting is already being disrupted, raising concerns about food supplies in the world’s most populous region.
Sea-surface temperatures in the region exceeded El Nino thresholds, and atmospheric indicators all aligned with the phenomenon, Australia’s Bureau of Meteorology said.
“Forecasts are pointing towards a strong to very strong El Nino event, based on the extent of warming in the central tropical Pacific,” it added. “Around half of the models indicate this event could peak at levels among the highest observed since 1950.”
Scientists have said climate change will supercharge the effects of this year’s El Nino.
A periodic warming of sea-surface temperatures in the central and eastern parts of the Pacific Ocean, El Nino is linked to less rainfall in winter and spring, particularly on Australia’s east coast, and higher southern daytime temperatures, the bureau said.
The weather phenomenon is particularly damaging to Australia, as it affects agricultural production in the country, which ranks among the world’s largest exporters of wheat, sugar and beef.
The last El Nino experienced in Australia, which was from 2023 to 2024, caused the driest three-month period on record.
One of the strongest such events, occurring in 2015 and 2016, brought widespread drought and reduced grain and oilseed output. REUTERS
