El Niño has formed in the Pacific and is expected to strengthen through late 2026, with a 63% chance of reaching a very strong level. Forecasts warn of hotter global temperatures and extreme weather, while impacts will vary by region. Scientists urge preparation and climate action as nations monitor evolving conditions.
El Niño has strengthened and is forecast to reach the strongest category by fall, bringing droughts, heavy rains, heat waves, and shifts in hurricane activity. Forecasts indicate the event will influence global weather patterns this fall and winter, with warnings of significant regional impacts.
Meteorological agencies and the UN have reported a very strong El Niño that has continued to intensify in August 2026. Forecasts show record-warm Pacific sea-surface temperatures, rising global heat and an elevated risk of droughts, floods and food insecurity that will push tens of millions more people into acute hunger this year and next.
