El Niño weather forecast

El Niño is a recurring, high-impact geophysical phenomenon that directly influences India's monsoon patterns, agricultural output, and food security, making it a standard and frequently tested topic in both Geography and Disaster Management.

Notes

  • 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.

Part of a longer story

This is day 1 of 2 in El Nino weather phenomenon development, which has been running since 25 August 2026. Reading it whole is usually worth more than reading today alone — the exam asks how something developed.
