Record-Strength El Niño Sets Stage for Diverse Weather and Economic Impacts
9/8/2026, 12:31:31 PM
Core Forecasts Across Regions
- New England – The Farmer’s Almanac predicts a “complicated” 2026/2027 winter with rain or mixed precipitation on the coast and heavy, wet snow inland.
- Pacific Northwest (U.S.) – Oregon state climatologist Larry O’Neill says a “super El Niño” is shaping up “off the charts.” NOAA assigns a 90% chance of a very strong event, with most precipitation likely as rain.
- United Kingdom – Met Office forecaster Adam Scaife warns the unusually large El Niño could produce a prolonged wet, stormy winter.
- Australia – Rabobank analyst Michael Harvey warns hot, dry conditions in eastern Australia could raise food prices, while CBA economist Dennis Voznesenski notes a third of global grain exports are currently stalled.
Background on the Current El Niño
El Niño occurs when Pacific trade winds weaken, allowing warm water to shift eastward, heating the atmosphere and reinforcing the pattern. The present event is projected to become the strongest on record, intensifying ocean temperatures that already influence global climate systems. Historically, strong El Niños have altered jet streams, moved storm tracks and triggered droughts, floods and temperature extremes worldwide.
Data & Statistics
- Farmer’s Almanac claims 80%-85% regional accuracy; a 2010 University of Illinois study found ?52% accuracy for monthly precipitation forecasts and ?51% for temperature forecasts.
- NOAA cites a 90% probability of a very strong El Niño this winter.
- In Australia, global wheat prices have risen about one-third since early July, while Brent crude surpassed US$97 a barrel, a 35% increase since July.
- The World Meteorological Organisation expects the El Niño to peak in November and persist until at least February 2027.
Official Statements & Responses
Larry O’Neill emphasizes the unprecedented nature of the event, noting that “we’re kind of in uncharted territory about exactly what kind of impacts we could get with this.” He cautions that heavy rain could trigger landslides after this summer’s wildfires.
Michael Harvey points to the “clear” risk that hot, dry weather in eastern Australia will affect food pricing over the next twelve months.
Dennis Voznesenski highlights supply-chain strain, stating that “a third of global grain exports are stuck right now.”
Adam Scaife explains that strong El Niños can reverse the usual late-winter easterly wind pattern over the UK, leading to milder, wetter conditions.

What’s Next
NOAA expects the El Niño to reach peak intensity in November and remain influential through February 2027, shaping winter weather preparedness, agricultural planning and market expectations across the affected regions.
