NOAA’s Climate Outlook for 2026 Hurricane Season
The National Oceanic and Atmospheric Administration (NOAA) has released its latest climate projections, suggesting that an El Niño phenomenon is likely to develop during the middle of the 2026 Atlantic hurricane season. Historically, this period has seen a notable decrease in both hurricane and tropical cyclone activity in the region.
El Niño, one of the three phases of the El Niño Southern Oscillation (ENSO), is a natural climate cycle attributed to variations in temperature and atmospheric conditions in the Pacific Ocean. It significantly influences global weather patterns. In contrast, La Niña involves cooler conditions, while ENSO neutral indicates temperatures close to the long-term average.
This winter, the La Niña phase contributed to recurring arctic air in the eastern United States, which resulted in active winter storms and record or near-record snowfall in many areas of the Northeast.
Currently, NOAA reports that ENSO is transitioning to a neutral state and shows increased signs of an impending summer El Niño, which aligns with long-term forecasts for 2025.
The chances of El Niño developing as the peak of the hurricane season approaches are estimated to be between 50% and 60%.
Typically, El Niño alters winds in a way that can hinder the formation of tropical cyclones in the Atlantic. If sea temperatures in the Pacific rise, combined with increased updrafts linked to El Niño, strong westerly winds may form across the Caribbean Sea and Major Development Region (MDR).
Winds associated with El Niño can either tilt or disrupt tropical systems, which often leads to more stable atmospheric conditions and inhibits their intensification.
Data from historical trends supports these expectations. During La Niña years, the Atlantic hurricane season tends to be busier, averaging about 14 named storms and 7 hurricanes, while El Niño years usually see fewer storms, with averages dropping to around 10 named storms and about 5 hurricanes.
However, the FOX Prediction Center indicates that unusually high sea surface temperatures in the Atlantic may lessen the typical influence of El Niño on tropical storms.
This anticipated shift to El Niño follows a weak La Niña period experienced during the 2025 hurricane season, which, notably, did not cause any landfalls in the U.S. but did witness three significant storms, including the historic Category 5 Hurricane Melissa that caused extensive damage in Jamaica.
While these seasonal outlooks can effectively highlight broad trends, it’s the specific atmospheric patterns on any given day that ultimately dictate the development and trajectory of tropical systems.
