The 2026 Atlantic hurricane season officially opened June 1, and for the first time in years, forecasters are predicting a quieter stretch ahead. NOAA puts the odds of a below-normal season at 55% — a striking shift after several relentlessly active years.
The force behind that forecast is a rapidly warming tropical Pacific, where ocean surface temperatures have climbed roughly 5°F since January, pointing toward what could become a strong El Niño event by late 2026. But forecasters are careful with their optimism: history shows that even suppressed seasons can deliver catastrophic storms — and millions remain in the path of whatever does develop.
NOAA’s Forecast: Fewer Storms, but Not Zero Risk
NOAA released its official 2026 outlook on May 21, projecting 8 to 14 named storms, 3 to 6 hurricanes, and 1 to 3 major hurricanes reaching Category 3 or higher. The numbers sit below recent averages. The agency assigns a 55% probability to a below-normal season, 35% to near-normal activity, and just 10% odds of an above-normal year.
Those figures sound reassuring — until forecasters remind you what they cannot guarantee.
“Although El Niño’s impact on the Atlantic basin can often inhibit hurricane development, uncertainty remains about how each season will unfold,” said Ken Graham, director of NOAA’s National Weather Service. “That is why it is essential to review your hurricane preparedness plan now. It only takes one storm to make a season very bad.”
That warning carries real weight. A single well-placed storm can reshape a coastline, flood a city, and displace thousands — regardless of how quiet the rest of the season turns out to be.
Why El Niño Quiets the Atlantic
El Niño is the warm phase of the El Niño–Southern Oscillation cycle. When active, sea surface temperatures in the tropical Pacific rise above average, triggering atmospheric changes that ripple across the globe.
The most consequential effect in the Atlantic is an increase in wind shear — the variation in wind speed and direction across different atmospheric layers. High wind shear disrupts developing tropical systems before they can organize into full hurricanes, and the stronger El Niño grows, the more pronounced that suppression tends to be.
The current warming has been rapid. Tropical Pacific surface temperatures have climbed roughly 5°F (3°C) since January 2025, driven partly by unusually strong westerly winds pushing warm water eastward. Seasonal forecast models broadly agree that El Niño is likely to peak at strong-to-very-strong intensity by late 2026 or early 2027 — right as the Atlantic season reaches its most active months.
Lessons From Past Strong El Niño Seasons
History offers a useful reality check. The five most recent strong El Niño years — 2023, 2015, 1997, 1982, and 1972 — all produced below-average Atlantic seasons. None produced zero consequences.
In 2023, El Niño intensified as the season progressed, yet Hurricane Idalia still struck Florida’s Big Bend region as a Category 3 storm. In 2015, no hurricane made U.S. landfall, but Hurricane Joaquín devastated the Bahamas. Both 1997 and 1982 saw only nine named storms each — well below the 1991–2020 average of 14 — yet storms still reached land.
The 1972 season is perhaps the clearest example. With just seven named storms, it ranked well below average. Hurricane Agnes formed in mid-June, struck the Florida Panhandle, then tracked northward, triggering catastrophic flooding across Pennsylvania and causing millions of dollars in damage and multiple deaths. Suppressed activity shifts the odds. It does not eliminate the threat.
The Wild Card: Warm Atlantic Waters Remain
Even as El Niño tightens its grip on the atmosphere, the Atlantic is not fully cooperating with the quieter forecast. Sea surface temperatures in the western Caribbean, along the Central American coast, and in North American coastal waters are still running above average — and warm water is the primary fuel that powers tropical storms.
When wind shear weakens locally, even briefly, a storm tracking over warm water can intensify rapidly. That creates particular danger near the coast, where communities have less time to prepare. Eastern Atlantic temperatures are currently below average, which limits early-season development farther out at sea, though forecasters expect those waters to warm as summer progresses. Wind shear is not uniform across the basin, leaving pockets of vulnerability even during an otherwise suppressed season.
Preparedness Still Matters — Maybe More Than Ever
The combination of warm coastal waters and a peak El Niño during August through October creates a specific risk: storms that form close to land and intensify faster than residents can respond. Rapid intensification has become a growing concern in recent seasons, and the conditions for it don’t simply vanish because El Niño is present.
NOAA is urging households and communities to review their hurricane preparedness plans before the season’s most active stretch arrives. Know your evacuation zone. Have supplies ready. Understand that a forecast of fewer storms is not a forecast of no storms.
Forecasters are clear about the limits of prediction. El Niño’s broad influence is measurable, but how it interacts with any individual storm — its track, timing, and intensity at landfall — remains deeply uncertain. The season ahead may well be quieter than the last several. Whether it is safe depends entirely on where the storms that do form decide to go.
