Strong El Niño conditions in the equatorial Pacific have driven unusually high vertical wind shear across the Atlantic basin, suppressing intensification and keeping all seven named storms (Arthur through Gonzalo) below the 64-knot Saffir-Simpson hurricane threshold as of late September 2026. This has produced zero hurricanes and an accumulated cyclone energy (ACE) value roughly 91% below the 1991–2020 average, consistent with NOAA and Colorado State University seasonal outlooks that projected below-normal activity. With peak season passed and shear, drier mid-level air, and cooler sea-surface temperatures expected to persist, the latest model guidance favors limited additional development through November, supporting the market’s heavy weighting toward 0–3 total hurricanes.
