Colorado State University on Wednesday dropped its 2026 Atlantic hurricane season outlook, citing growing confidence that a developing strong El Niño will suppress tropical storm activity across the basin. The revised forecast now calls for 11 named storms, 5 hurricanes, and 2 major hurricanes, all below the long-term average.
The numbers represent a meaningful retreat from CSU's April projection, which anticipated 13 named storms and 6 hurricanes. The shift matters for millions of Americans along the Gulf and Atlantic coasts who make insurance, preparedness, and property decisions partly on the strength of these widely watched seasonal outlooks.
CSU's updated forecast also aligns with NOAA's seasonal forecast, released several weeks ago. That agreement between the two most prominent hurricane forecasting operations lends additional weight to the below-average outlook, though both teams stress that a quieter season does not mean a safe one.
The driving force behind the downgrade is El Niño, one of three phases of the climate cycle known as the El Niño-Southern Oscillation, or ENSO. El Niño describes warmer-than-average water across the equatorial Pacific. When those temperatures climb more than 2 degrees Celsius above average, forecasters classify conditions as a strong El Niño.
NOAA's Climate Prediction Center released a brief stating that neutral conditions have taken hold and that El Niño will likely develop sometime in the next six months. Most long-range models show El Niño peaking in strength as the hurricane season ends in November.
The mechanism is straightforward. During El Niño, above-average water temperatures in the central and eastern Pacific Ocean produce strong upper-level winds that hinder tropical development in the Atlantic. Those same conditions enhance storm development in the Eastern Pacific instead, effectively robbing the Atlantic basin of the atmospheric ingredients that fuel hurricanes.
CSU's forecasters said they now have increased confidence that a developing strong El Niño will become the dominant factor this season, overcoming other forecast ingredients that might otherwise favor more tropical development.
An average Atlantic hurricane season produces 14 named storms, 7 hurricanes, and 3 major hurricanes. CSU's revised numbers, 11, 5, and 2, fall below every one of those benchmarks. The updated forecast also puts the chance of a major hurricane making landfall anywhere along the entire U.S. coastline at 24 percent this year.
That figure sits well below the historical average of 43 percent for the period between 1880 and 2020. For coastal homeowners and local governments already stretched thin by rising insurance premiums and post-storm rebuilding costs, the lower probability is welcome news, on paper.
But Dr. Phil Klotzbach, a hurricane specialist and senior research scientist within CSU's Department of Atmospheric Science, joined FOX Weather to discuss the reasons behind the forecast change and the updated outlook. Both Klotzbach and FOX Weather Hurricane Specialist Bryan Norcross, along with other CSU forecasters, cautioned that even in seasons with fewer storms, it only takes one to create major impacts.
That warning is not academic. History backs it up.
The FOX Forecast Center noted that a similar atmospheric setup occurred in 2023, when El Niño was also present but record-warm sea surface temperatures helped offset the suppressing effects.
"A similar setup occurred in 2023, when record-warm sea surface temperatures helped offset the suppressing effects of El Niño."
That season produced more activity than many forecasters initially expected, precisely because unusually warm ocean water gave storms enough fuel to develop even under El Niño's hostile upper-level wind patterns. The lesson: El Niño tilts the odds, but it does not guarantee a quiet season.
CSU also referenced Hurricane Joaquin, which reached Category 4 status during a Super El Niño year. And a satellite image accompanying the forecast showed Hurricane Melissa south of Jamaica on Sunday, October 26, 2025, a reminder that powerful storms can form even when seasonal totals run below average.
CSU plans to issue a mid-season forecast update in August, when forecasters will have the benefit of observing how El Niño actually develops through the early summer months rather than relying on model projections. By then, sea surface temperatures across the Atlantic and equatorial Pacific will tell a clearer story about whether the suppressing signal holds or whether warm water complicates the picture again, as it did in 2023.
NOAA's Climate Prediction Center will also continue monitoring ENSO conditions. The agency's brief indicates El Niño development is expected within the next six months, but the timing and intensity remain uncertain enough that the August update could shift the numbers in either direction.
For residents from the Texas Gulf Coast to the Carolinas, a below-average forecast is a reason for cautious optimism, not complacency. Insurance markets, emergency management budgets, and evacuation planning do not operate on seasonal averages. They operate on the single worst storm that actually arrives.
The alignment between CSU and NOAA on a below-average season is notable. Two independent forecasting operations reading the same atmospheric signals the same way adds credibility to the outlook. But both have been careful to frame the numbers in context: fewer storms overall still leaves room for devastating individual events.
Coastal communities that have watched premiums climb and coverage options shrink in recent years know the math. A 24 percent chance of a major landfalling hurricane is lower than the 43 percent historical average, but it is not zero. And for the town that draws the short straw, the seasonal total is irrelevant.
Nature doesn't care about averages. Preparation still beats prediction every time.
