The Atlantic just posted its quietest hurricane-season start in at least 60 years, with no hurricane by mid-September

The Atlantic hurricane season has reached its historical peak with an unusual absence of storms strong enough to earn hurricane status, a lull that forecasters describe as the quietest start to the season in at least six decades. Five systems had already picked up names by the second week of September, yet none had strengthened past tropical storm force, leaving meteorologists and coastal residents watching a season that has defied the calendar’s busiest stretch.

Why September 10 is the marker forecasters watch

Atlantic hurricane season runs officially from June 1 through November 30, but activity is never evenly spread across those six months. Decades of storm records show that activity builds slowly through the summer and peaks around September 10, the date climatologists use as the statistical high point of the season based on accumulated cyclone energy and storm frequency across more than a century of records.

Reaching that benchmark with zero hurricanes is significant precisely because the odds of the season staying quiet only shrink from there; historically, most of a given year’s most intense storms have already formed by early September, not after it. Forecasters use the date as a checkpoint rather than a firm cutoff, since the western Caribbean and Gulf of Mexico can still produce dangerous late-season storms well into October in years that started slowly.

Five named storms, zero hurricanes

According to weather.com’s tracking of the 2026 season, five systems had reached tropical storm strength by the peak-season date, but every one weakened, stalled, or dissipated before crossing the 74 mile-per-hour wind threshold that defines a hurricane. That combination, a handful of named storms without a single hurricane by mid-September, has not occurred in at least 60 years of Atlantic basin records, according to the report.

The distinction matters beyond bragging rights for forecasters, since hurricanes carry the storm surge, sustained wind damage, and inland flooding potential that tropical storms typically do not produce at the same scale. A season can still produce significant rainfall and coastal flooding from tropical storms alone, but the absence of any system reaching hurricane strength through the statistical peak is what forecasters are flagging as historically unusual.

NOAA’s below-normal outlook holds through the peak

The National Oceanic and Atmospheric Administration entered the 2026 season predicting below-normal activity, and the agency reaffirmed that outlook as the season reached its climatological high point. The NOAA news release pointed to atmospheric and oceanic conditions working against storm development across the basin, a forecast that has tracked closely with what has actually unfolded on the water.

A below-normal seasonal outlook does not guarantee a quiet season on its own, since a single well-placed storm can still cause outsized damage regardless of the overall count, but the absence of any hurricane through the peak date lines up with the conditions NOAA identified months earlier. The agency typically updates its outlook in early August, midway through the season, and this year’s mid-season revision kept the below-normal call rather than upgrading it.

What is suppressing storm development this year

Hurricanes need a specific combination of warm ocean water, low wind shear, and moist mid-level air to organize and intensify, and forecasters have pointed to disruptions in that recipe as the likely explanation for the quiet stretch. Stronger-than-typical wind shear across parts of the tropical Atlantic can tear apart a storm’s structure before it has a chance to strengthen, scattering the thunderstorm clusters that would otherwise wrap around a developing center.

Plumes of dry, dusty air moving off the Sahara Desert can also choke off convection over the open ocean, starving fledgling systems of the moisture they need to build. Sea surface temperatures across parts of the basin have played a role as well, with some stretches of water running cooler relative to recent years, denying storms the fuel that has powered especially intense seasons in the past. Any one of these factors alone can weaken a season; forecasters have suggested this year’s lull reflects several working against storm formation at once.

Ten weeks still remain on the calendar

A quiet peak does not mean the season is over. Hurricane season continues through the end of November, and history includes years when activity picked up sharply after a slow start, including seasons where late-forming storms went on to make significant landfalls well past the traditional September peak.

Water temperatures in parts of the Gulf of Mexico and the western Caribbean often remain warm enough to support storm development into October, and forecasters caution against reading a quiet first ten weeks as a guarantee for the remainder of the season. Coastal residents from the Gulf Coast to the Eastern Seaboard are generally advised to maintain the same preparedness posture through November regardless of how the season has unfolded so far, since the absence of an early hurricane says little about what the season’s final weeks might bring.
