Atlantic Hurricane Season Hits Historic Lull as El Niño Shifts Storm Risk to Pacific

Historic Absence of Atlantic Hurricanes

The Atlantic basin has entered the most volatile window of its hurricane season with an unprecedented lack of major activity. Despite the official season running from 1 June to 30 November, the region has failed to produce a single hurricane as of 10 September—the date NOAA identifies as the climatological peak of the season.

While five named storms—Arthur, Bertha, Cristobal, Dolly, and Edouard—have formed, none progressed beyond tropical-storm strength. This stagnation has resulted in an Accumulated Cyclone Energy (ACE) of just 4.4 units, representing a 92% drop compared to the 1991–2020 benchmark.

If no hurricane develops by Saturday, the 2026 season will set a new satellite-era record for the latest first Atlantic hurricane. The previous records were held by Gustav in 2002 and Humberto in 2013, both of which formed on 11 September.

The El Niño Influence on Storm Tracks

The primary driver of this Atlantic dormancy is the strengthening El Niño in the central and eastern equatorial Pacific. This climate pattern generates high vertical wind shear across the Caribbean, the Gulf of Mexico, and the deep tropical Atlantic.

Vertical wind shear acts as a disruptive force, tilting developing storms and preventing the organized thunderstorm structures required for a system to intensify into a hurricane. Matthew Rosencrans, NOAA’s lead seasonal hurricane forecaster, described the current atmospheric environment as particularly hostile to tropical development.

NOAA currently projects a 75% probability of a below-normal Atlantic season, with only a 5% chance of an above-normal year. The agency expects a total of seven to 13 named storms, two to six hurricanes, and up to two major hurricanes by the season's end on 30 November.

Pacific Basin Experiences Opposite Trend

While the Atlantic remains quiet, the eastern Pacific has seen a surge in activity. By 10 September, the Pacific recorded 14 named storms, four hurricanes, and two major hurricanes.

The Pacific's ACE total has reached 99.1, which is approximately 36% above the 1991–2020 benchmark. This divergence is a direct result of El Niño, which suppresses Atlantic development while simultaneously reducing wind shear in the Pacific, creating a supportive environment for cyclone intensification.

Implications for Global Travel and Tourism

The geographical shift in storm activity creates a divided risk map for travelers:

• Caribbean and US Gulf Coast: These regions are currently experiencing a lower immediate risk of flight disruptions and resort closures. However, because 60% of Atlantic activity typically occurs after 10 September, the risk remains present through November.
• Hawaii and US West Coast: These destinations face heightened exposure to tropical weather and indirect atmospheric effects driven by the active Pacific basin.

Key Takeaways

• Record Potential: The Atlantic is on the verge of the latest first-hurricane start in the satellite era.
• Climate Driver: El Niño is the catalyst, increasing wind shear in the Atlantic while lowering it in the Pacific.
• Risk Shift: Tropical volatility has moved from the Caribbean/Gulf regions toward Hawaii and the Pacific coast.
• Not Over Yet: Despite the lull, the Atlantic season continues until 30 November, with a significant portion of activity usually occurring in late September and October.

FAQ

Why are there no hurricanes in the Atlantic this year? Strong El Niño conditions have increased vertical wind shear, which disrupts the organization of tropical storms and prevents them from intensifying into hurricanes.

Does a quiet Atlantic mean Hawaii is safe? No. El Niño creates the opposite effect in the Pacific, reducing wind shear and making it easier for hurricanes to form, which increases the risk for Hawaii and the West Coast.

When does the Atlantic hurricane season officially end? The season runs from 1 June to 30 November.
