By September 23, 2026, not a single Atlantic tropical storm had intensified into a hurricane — a first in 60 years of satellite observation. Six named storms had formed, but none reached the 119 km/h threshold for Category 1 status. The accumulated cyclone energy for the season sat at a record low. NOAA's lead hurricane forecaster Matthew Rosencrans put it plainly: "In the satellite era, we have never had a year without a hurricane." The cause is the El Niño-Southern Oscillation, now exceeding a 3°C sea surface temperature anomaly in the key Pacific monitoring region — placing it among the strongest events on record. El Niño weakens or reverses the Pacific trade winds, shifting the jet stream and dramatically increasing vertical wind shear over the Atlantic. That shear tears apart developing storm systems before they can organize. The stronger the El Niño, the stronger the shear, and the more suppressed the Atlantic season becomes. But the energy doesn't vanish. It migrates. The eastern Pacific has been hyperactive, producing four hurricanes in the past month alone, including Hurricane Polo — one of the most powerful Pacific cyclones in decades. El Niño's warmer Pacific waters and reduced wind shear in that basin create ideal storm-building conditions. Storms also form farther east, giving them longer life spans and more time to intensify before approaching land. NOAA expects an above-average Pacific hurricane season. The redistribution extends into the western Pacific and Indian Ocean. Typhoon tracks in the Asian Pacific shift northward during El Niño, increasing risk for Guam, the Northern Mariana Islands, Japan, and the Korean Peninsula rather than the typical targets in Southeast Asia. In the Indian Ocean, increased wind shear mirrors the Atlantic's suppression pattern, generally reducing cyclone activity and lowering risk for Madagascar and Mozambique — though the World Meteorological Organization's Anne-Claire Fontan noted a nonlinear, bell-shaped relationship where both extreme El Niño and extreme La Niña suppress activity in that basin. The Atlantic's quiet doesn't mean safety. NOAA warned that storms forming in El Niño years tend to appear closer to the US East Coast and Gulf of Mexico — leaving coastal communities with far less warning time than storms that develop deep in the tropics. The hurricane season runs through November 30, and a single late-season event could still cause catastrophic damage. Layered on top of the natural oscillation is the longer-term warming signal. WMO Secretary-General Celeste Saulo warned of worsening droughts and floods as El Niño intensifies in a warmer climate. The UK's Met Office has suggested the combined effects could shatter heat records in 2027. A Climate Impact Lab report projected that extreme heat during this El Niño period could cause nearly half a million additional deaths worldwide, concentrated in the Global South. El Niño weakens the Indian monsoon, threatening severe drought on the subcontinent. The ENSO cycle is not climate change — it recurs every two to seven years. But it operates inside a climate system that is measurably warmer than in previous cycles, amplifying extremes in every direction. Saharan dust, another natural suppressor, adds a further wildcard to Atlantic forecasting. The quiet Atlantic is not a reprieve; it's the visible face of a global redistribution of energy whose costs are landing on the most vulnerable populations and least-prepared infrastructure.
