Colorado State University's hurricane team is dialing down expectations for the 2026 Atlantic season—but not the warnings that come with it. Researchers at CSU, pioneers of long-range hurricane outlooks, project 13 named storms, six hurricanes, and two major hurricanes (Category 3 or stronger) between June 1 and Nov. 30, reports WPLG Miami. That's a notch below the 30-year average of 14 named storms, seven hurricanes, and three major hurricanes, and the group says overall activity, measured by Accumulated Cyclone Energy, could be the weakest since 2015. It's also the first time since 2023 that CSU has opened hurricane season with a below-normal forecast. The report came with a warning, notes Al.com: "As with all hurricane seasons, coastal residents are reminded that it only takes one hurricane making landfall to make it an active season."
The main factor behind the quieter outlook: a likely powerful El Niño taking shape in the eastern Pacific. When those waters heat up, they tend to disrupt Atlantic storm formation by increasing hostile winds and sinking air—especially if the El Niño is strong. Models suggest a rapid shift from the recent La Niña pattern to a robust El Niño by late summer, with some projections hinting at a "super" event rivaling the major episodes of 1982, 1997, and 2015. Unlike the hyperactive 2023 season—when very warm Atlantic waters appeared to blunt El Niño's dampening effect—current forecasts show a relatively cool tropical Atlantic going into the peak months, which would give El Niño more leverage to suppress storms.
Forecasters stress, however, that seasonal outlooks don't say where or when storms will strike—and they get more reliable as summer approaches. Previous "quiet" forecasts have been followed by busy seasons, and history shows that even a slow year can deliver a devastating landfall: 1965 produced just one major hurricane, but that storm was Hurricane Betsy, which caused severe damage in South Florida and Louisiana.
