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.
The latest data show global sea temperatures have reached record highs in August 2026 as El Ni 0o intensifies, driven by natural variability and long-term warming. Forecasts indicate the warmth will continue into 2027, with wide-ranging impacts on weather, seas and economies. Governments warn of increased risks to vulnerable communities and fisheries.
El Niño is strengthening and is likely the strongest in modern records. Forecasts foresee hotter global temperatures, worsened heatwaves, floods and droughts across regions as climate warming interacts with the natural cycle.
El Niño has strengthened toward historic levels, with NOAA and other forecasters projecting a 75% chance of a record-breaking event in late 2026. The phenomenon is driving higher global temperatures, shifting rainfall, and fueling droughts and floods across regions. Governments warn households to prepare for potential disruptions and to stock essentials.
A global report shows 2025 was among the driest years for river flows in 35 years, with groundwater and glaciers dwindling. Major river systems are under stress from drought, pollution and overexploitation, prompting calls for action and data-sharing to protect communities and economies.
