The essentials
NOAA projects below-average 2026 Atlantic hurricane activity due to El Niño suppression.
NOAA has forecasted a below-average 2026 Atlantic hurricane season, signaling a shift from recent years of elevated storm activity. The outlook is primarily driven by El Niño conditions, which are expected to suppress Atlantic hurricane activity through increased wind shear and other atmospheric factors that inhibit storm development.
El Niño's influence creates unfavorable conditions for tropical cyclone formation in the Atlantic basin. While specific storm counts remain subject to forecast refinement, the below-average designation indicates fewer hurricanes are anticipated compared to climatological averages.
This outlook provides important context for the 2026 Atlantic hurricane season, as residents and emergency managers plan preparedness measures based on seasonal expectations.

El Niño mechanism explains reduced Atlantic hurricane outlook
El Niño strengthens wind shear and alters atmospheric circulation patterns in the Atlantic, creating conditions hostile to hurricane development. These physical mechanisms provide scientific basis for NOAA's below-average seasonal forecast, demonstrating how ocean-atmosphere interactions influence tropical cyclone potential across ocean basins.
Below-average forecast shapes 2026 hurricane season planning
A below-average outlook may influence resource allocation and preparedness priorities for coastal communities and emergency management agencies. However, even reduced-activity seasons can produce significant storms, requiring continued monitoring and readiness despite the more favorable statistical expectations for the 2026 season.
