El Niño weather forecast

  • El Niño is a natural climate oscillation occurring every two to seven years, characterized by warming sea surface temperatures in the tropical eastern Pacific.
  • The phenomenon triggers global changes in wind patterns, atmospheric pressure, and rainfall, while increasing global average temperatures.
  • An El Niño event is defined by water temperatures rising at least 0.5 degree Celsius above the baseline.
  • Current forecasts predict a record-breaking El Niño, with Pacific water temperatures potentially peaking over 3 degrees Celsius above the norm.
  • Regional impacts include drier conditions in southeast Asia, Australia, southern Africa, and northern Brazil, and wetter conditions in the Horn of Africa, the southern United States, Peru, and Ecuador.
  • The event is currently causing below-normal rainfall in India and is expected to increase storminess in the U.K. by November.
  • The cumulative effect of this El Niño and climate change is projected to make 2027 the warmest year on record globally.
  • Current Pacific temperatures are approximately 2.6 degrees Celsius above the 30-year rolling average.

El Nino weather phenomenon forecast

  • The World Meteorological Organisation (WMO) forecasts that the current El Nino phenomenon will persist through February 2027 with near 100% certainty.
  • The phenomenon is driven by exceptionally warm Pacific Ocean temperatures and may become the strongest ever recorded.
  • El Nino is defined as a periodic warming of sea surface temperatures in the eastern Pacific caused by the weakening of trade winds.
  • It typically occurs every two to seven years and lasts up to 12 months.
  • El Nino impacts global climate patterns, leading to significant shifts in rainfall and temperature, including increased risks of droughts and typhoons.
  • The WMO is prioritizing early warning systems and preparedness efforts to mitigate the impact on member states.
