The National Oceanic and Atmospheric Administration (NOAA) announced on Thursday that the current El Niño climate pattern has intensified and is expected to remain active through at least March. Agency officials stated that the phenomenon, characterized by warming Pacific Ocean waters, is currently categorized as "very strong" and could have impacts through next spring that may be considered historic.
El Niño is a recurring climate pattern that occurs every two to seven years when sea surface temperatures in the tropical Pacific rise at least 0.5 degrees Celsius above average for an extended period. NOAA reported that as of Nov. 12, sea surface temperature anomalies reached 4 degrees Celsius. The agency considers the event "very strong" if temperatures remain 2 degrees Celsius or more above average for five consecutive three-month periods.
The current cycle has contributed to record-low tropical storm and hurricane activity in the Atlantic basin due to increased Saharan dust and atmospheric conditions that inhibit storm development. Conversely, warmer Pacific waters fueled record intensity in that ocean, where meteorologists have tracked 32 typhoons so far in 2026. Two of these, Super Typhoon Sinlaku in April and Super Typhoon Champi in October, reached Category 5-equivalent strength with 185 mph winds.
The economic scale of the event involves industries including fishing, agriculture, and utilities. Farmers in the northern portion of South America, central Africa, southern Asia, and Australia face elevated drought risks, while agricultural sectors in eastern Asia and southern South America face potential flooding from increased precipitation. These extremes have already prompted multiple countries in Central and South America to declare national emergencies as drought and record precipitation have affected agriculture.
Utility companies that rely on wind and rainfall for power generation may see impacts as patterns shift. Additionally, coastal areas on the U.S. West Coast have already seen tangible impacts, as 21 named tropical systems in the Eastern Pacific generated waves that eroded luxury beaches. NOAA expects El Niño conditions to persist through March, meaning the atmospheric changes affecting weather forecasts will continue for several months.
