Atlantic hurricane season at 7% of normal as El Niño smothers storms

For climate and energy risk managers, a record-quiet Atlantic hurricane season is a stress test of how natural variability interacts with a warming ocean. The 2026 season has produced zero hurricanes through the climatological peak, with basin-wide activity at just 7% of normal — yet forecasters warn the lull is no reason to discount physical risk to Gulf energy infrastructure and coastal grids. Understanding why El Niño is winning the tug-of-war against warm Atlantic waters matters for seasonal planning, insurance pricing, and resilience investment.

The 2026 Atlantic hurricane season has produced a modern-era record for quiet, with not a single hurricane forming through the first half of September, which is traditionally the climatological peak of the basin's six-month storm season. According to the National Hurricane Center, no Atlantic hurricanes have spun up so far this year and none are likely to form for at least another week, even though this is normally when the season would be at its most active. Only five relatively weak, short-lived tropical storms have developed all season. On Saturday, September 12, 2026, the Atlantic set a record for the longest start to a season without a storm reaching hurricane strength — sustained winds of at least 74 mph (119 km/h) — in the satellite era, according to Nick Novella, a meteorologist at the government's Weather Prediction Center.

The 'satellite era' qualifier matters. Before the 1950s, a handful of years appear to have gone this late without a recorded hurricane, but meteorologists do not trust those records because ocean monitoring was incomplete and many storms that never approached land or shipping lanes went undetected. Only with the satellite coverage that began in the 1960s could forecasters confidently track every system from formation to dissipation, which is what makes the 2026 milestone a genuine record rather than a data artifact.

The scale of the inactivity is even clearer in the aggregate. Overall hurricane activity, measured by Accumulated Cyclone Energy — a metric that accounts for the number of storms, their intensity and their duration — is at a post-1950 record low, according to Colorado State University hurricane researcher Phil Klotzbach. Storm activity in the Atlantic is running at just 7% of normal for this point in the year, a startling deficit at what is usually the most active stretch of the season.

The driver is an enormous El Niño, the natural, temporary warming of the equatorial Pacific that reshapes global atmospheric circulation. Five experts told The Associated Press that El Niño is delivering what University at Albany atmospheric scientist Kristen Corbosiero called a 'triple whammy': vertical wind shear that 'decapitates' developing storms, dry air that starves them of moisture, and broad sinking motion that suppresses the upward convection hurricanes need to organize. 'It's really staggering, just how inhospitable the Atlantic is to anything that could form a tropical cyclone right now,' Corbosiero said. 'Anything that tries to form is just getting this triple whammy.'

The quiet is notable precisely because it defies the thermodynamic backdrop. Atlantic sea-surface temperatures have been warm — conditions that, in isolation, would favor more numerous and more intense storms. El Niño's dynamic suppression is overriding that fuel, illustrating that hurricane formation depends as much on the surrounding wind and moisture environment as on warm water. For climate science, the season is a natural-variability demonstration rather than evidence against the long-term, warming-driven trend toward stronger storms.

Experts cautioned against reading the lull as safety. Several pointed to 1992, when a quiet, late-starting season produced Hurricane Andrew, one of the most destructive U.S. landfalls on record. Because Accumulated Cyclone Energy and storm counts measure basin-wide activity rather than landfall risk, a single storm in an otherwise dead season can still be catastrophic. 'People shouldn't let down their guard because it just takes one storm, even during an El Niño, to be catastrophic,' experts said.
