Atlantic hurricane season 2026 sets a new record

Atlantic hurricane season reaches an unusually quiet milestone

Cybersecarmor.com – More than three months into the 2026 Atlantic hurricane season, the basin has yet to produce a single hurricane — an exceptionally late point in the calendar for that to happen. As of Sept. 12, no hurricane had developed anywhere in the Atlantic Ocean, establishing the latest date in the modern era without at least one hurricane.

The lack of activity is striking not only because hurricanes have been absent, but because the National Hurricane Center’s outlook map also showed no potential tropical cyclones. The season officially began June 1 and continues through Nov. 30, leaving time for conditions to change even after an unusually subdued summer.

A record-setting delay

Only two other seasons in the satellite record came close to this late-hurricane mark. In both 2002 and 2014, the first Atlantic hurricane arrived on Sept. 11. The 2026 season moved past those years without a hurricane forming.

Michael Lowry, a hurricane specialist at WPLG-TV in South Florida, captured the silence in his “Eye on the Tropics” Substack blog with a brief assessment:

“Crickets.”

The broader season has also lagged far behind its normal pace. An average Atlantic season produces 14 named storms, with seven reaching hurricane strength. By the usual Sept. 10 seasonal peak, the basin typically has generated about four hurricanes, along with additional tropical storms. This year, only five tropical storms had formed by that point.

Lowry described the early-September state of the basin in especially blunt terms:

“The Atlantic basin is as dead as it gets for early September.”

Why El Niño has made storm development difficult

A powerful El Niño has played a central role in suppressing Atlantic tropical activity. El Niño occurs when waters near the equator in the Pacific Ocean become warmer than normal. That ocean pattern can affect weather far beyond the Pacific, altering atmospheric circulation in ways that make it harder for tropical systems to organize in the Atlantic and Caribbean.

One of the most important effects is stronger vertical wind shear. Wind shear occurs when wind speed or direction changes sharply with height. Tropical cyclones need a relatively aligned atmosphere to build and maintain their circulation. Strong shear can tilt storms apart, displace thunderstorms from their centers and stop a developing system from becoming a hurricane.

Phil Klotzbach, a senior research scientist in Colorado State University’s Department of Atmospheric Science, said the summer’s shear levels have exceeded previous benchmarks. During early September, the 30-day average wind shear across the region was the strongest measured since the global satellite era began in 1979. It averaged more than 3 knots above every other year in that period.

The other four leading years for Atlantic vertical wind shear — 1979, 1986, 2015 and 1997 — each occurred during an El Niño phase. Seasonal outlooks had anticipated that El Niño would reduce hurricane development in 2026, and the season’s performance through mid-September has followed that expectation.

Tropical Storm Dolly, which formed Aug. 27, offered a recent example of those hostile conditions. Forecasters noted that satellite imagery showed the impact of shearing winds, and the system was expected to be brief. Dolly lasted less than 24 hours.

Dust and dry air add another obstacle

El Niño is not the only force keeping the Atlantic quiet. Jhordanne Jones, an assistant professor in Penn State’s Department of Meteorology and Atmospheric Science, said Saharan dust and dry air have been moving across the Atlantic at the same time El Niño has limited rising air needed for rainfall and thunderstorm development.

The combined effect makes it considerably harder for tropical disturbances to become organized storms.

“So it’s like a double suppression.”

Dry air and dust have helped extend drought conditions across portions of the tropical Atlantic. Puerto Rico provides one notable example: roughly 80% of the island was experiencing drought conditions on the U.S. Drought Monitor. Without a major shift in the pattern, Jones said the quiet period could continue.

“We’re not going to be seeing any activity for a while.”

Few storms does not mean no future risk

The season’s slow start should not be mistaken for a guarantee that the remaining months will be harmless. Tropical activity can increase rapidly when atmospheric conditions become more favorable, and hurricanes have formed in past years after similarly late starts. Residents of coastal areas and islands still have a reason to keep preparedness plans current through the official end of the season on Nov. 30.

Storm totals are only one way scientists judge a hurricane season. Another important measure is Accumulated Cyclone Energy, commonly called ACE. This index combines storm intensity and lifespan, giving more weight to powerful systems that remain active for longer periods.

Through Sept. 10, the Atlantic’s ACE total stood at 4.4. Klotzbach said that was the lowest value for this stage of any season since 1950. The number reflects both the limited count of tropical storms and the inability of those systems to persist or intensify.

Limits of the historical record

Comparisons with seasons before satellite coverage require caution. Before modern satellite monitoring, storms over open water could go unseen if they did not approach land, encounter aircraft reconnaissance or cross paths with ships. Matthew Rosencrans, a meteorologist at NOAA’s Center for Weather and Climate Prediction, noted that much of the early hurricane record was assembled from land observations, ship logs and aircraft reports.

Two seasons in the early 1900s are believed to have gone without a hurricane, but the incomplete observing network of that era creates substantial uncertainty. Klotzbach has warned that pre-1950 hurricane totals may be significantly undercounted, especially for storms that stayed far from populated coastlines.

Historical reconstructions by NOAA experts show that five seasons had a hurricane form after Sept. 11. That history underscores the key message of 2026’s extraordinary lull: the Atlantic has been unusually quiet, but the season is not over.
