Hurricane Season 2026: Season Opens Quiet as El Niño Suppresses the Atlantic
The 2026 Atlantic hurricane season is underway. June 1 opened with zero tropical activity and hostile conditions across the basin — El Niño's shear is already visible. NOAA forecasts 8–14 named storms with a 55% chance of below-normal activity. We analyzed every El Niño hurricane season since 1991.
June 1, 2026 — Hurricane season is officially underway. Day 1: zero activity.
The 2026 Atlantic hurricane season opened today with no tropical cyclone formation expected anywhere in the basin — the third consecutive year the season has started without a trackable system. Satellite imagery shows widespread dry air and strong upper-level winds, making the atmosphere too hostile for tropical development. That hostility has a name: El Niño. The Niño 3.4 index surged to +0.9°C in late May, nearly double the El Niño threshold. The shear suppression forecasters predicted is now showing up in real-time satellite data. CSU releases its updated June forecast on June 10 — we'll update this article with the revised numbers. NOAA's next update comes in early August.
May 22, 2026 — NOAA's official forecast is in: below-normal season
NOAA released its official 2026 Atlantic Hurricane Season Outlook on May 21. The numbers: 8–14 named storms, 3–6 hurricanes, 1–3 major hurricanes. NOAA assigns a 55% chance of below-normal activity, 35% near-normal, and just 10% above-normal. El Niño is 98% likely to develop during the season, with Pacific SSTs potentially rising 2°C+ above average — driving the strongest wind shear suppression in years. “Although El Niño's impact in the Atlantic Basin can often suppress hurricane development, there is still uncertainty in how each season will unfold,” said NWS Director Ken Graham. Atlantic ocean temps remain warmer than normal but below the record levels that fueled 2024's brutal season. Meanwhile, the May 13–14 super tornado outbreak (206 tornadoes, 78 deaths) demonstrated that El Niño suppression of hurricanes doesn't mean a calm severe weather season — it just redirects the energy.
The 2026 hurricane season is officially underway, and day one told us a lot: nothing. Zero tropical activity across the entire Atlantic basin. Satellite imagery showed dry air and hostile upper-level winds everywhere — the kind of conditions that kill hurricanes before they can form. NOAA's official forecast calls for 8–14 named storms, well below the 14-storm average. The reason is an El Niño that's no longer just a probability — Niño 3.4 hit +0.9°C in late May and is accelerating fast.
After 2024's brutal season (18 storms, $124 billion in damage, 252+ deaths from Helene alone), a quiet opener is welcome. But I've been doing this long enough to know “below average” doesn't mean safe. The 1992 season had just 7 named storms. One of them was Hurricane Andrew, a Category 5 that destroyed 63,000 homes in South Florida. The 2004 season developed during El Niño conditions and still produced 4 hurricane landfalls in Florida.
The question has evolved since April. Back then, the debate was whether El Niño shear could overpower warm Atlantic SSTs. Now the question is: if this El Niño hits +3.0°C — a level with no modern analog — does hurricane suppression become near-total? The June 1 data says the shear is winning so far.
Every 2026 Forecast, Compared
Four major forecast groups, four different answers. The most important number isn't named storms — it's major hurricanes (Category 3+), because those cause 85% of all hurricane damage despite making up only about 20% of landfalls.
| Source | Named Storms | Hurricanes | Major (Cat 3+) |
|---|---|---|---|
| CSU | 13 | 6 | 2 |
| TSR | 12 | 5 | 1 |
| AccuWeather | 11–16 | 4–7 | 2–4 |
| NOAA (Official) | 8–14 | 3–6 | 1–3 |
| U of Arizona | 20 | 9 | 4 |
| 30-yr Average | 14 | 7 | 3 |
CSU released April 9, 2026. TSR revised down from their December preliminary. AccuWeather released March 25. U of Arizona is the lone above-average forecast.
Why Forecasters Can't Agree: El Niño vs. Atlantic SSTs
This is the most interesting disagreement in hurricane forecasting in years. Here's the tension in plain terms:
Team “Below Average” (CSU, TSR, NOAA) — confirmed by June 1 data
El Niño is now 98% likely, with Niño 3.4 at +0.9°C and rising. June 1 satellite imagery showed exactly what these models predicted: dry air and hostile upper-level winds across the Atlantic, making tropical development impossible. When El Niño is strong, it creates vertical wind shear that tears apart developing hurricanes. In the two strongest El Niño years (1997-98 and 2015-16), the Atlantic produced just 8 and 11 named storms respectively. A +3.0°C event would produce shear levels with no modern precedent.
Team “Above Average” (U of Arizona)
Atlantic sea surface temperatures are at record levels. The North Atlantic is in a warm phase of its multidecadal oscillation (+AMO), and global SSTs set a new daily record in mid-April 2026. The University of Arizona argues this warmth provides so much fuel that hurricanes will form despite El Niño's shear. They point to 2023-24: a strong El Niño year that still produced 19 named storms because Atlantic temps were so extreme.
NOAA's May 21 forecast settled this — at least for now. Their range of 8–14 storms with 55% below-normal probability confirms El Niño shear is dominating their models. The floor of 8 named storms would be the quietest Atlantic season since 2014. If this El Niño reaches +3.0°C as ECMWF models project, even the U of Arizona's warm-SST argument becomes very hard to sustain. The 1997-98 super El Niño produced just 8 named storms, and this one may be stronger.
What El Niño Hurricane Seasons Actually Look Like
Forecasts are educated guesses. History is data. Here's what happened in every El Niño Atlantic hurricane season since 1991 — the good, the bad, and the ones that defied the “El Niño = quiet season” assumption.
| El Niño Year | Strength | Storms | Hurricanes | Major |
|---|---|---|---|---|
| 2023-24 | Strong | 19 | 7 | 3 |
| 2015-16 | Super | 11 | 4 | 2 |
| 2009-10 | Moderate | 9 | 3 | 2 |
| 2006-07 | Moderate | 10 | 5 | 2 |
| 2004-05 | Weak | 15 | 9 | 6 |
| 2002-03 | Moderate | 12 | 4 | 2 |
| 1997-98 | Super | 8 | 3 | 1 |
| 1991-92 | Moderate | 7 | 4 | 1 |
The Uncomfortable Pattern
The average El Niño season since 1991 produced roughly 11 named storms — 21% fewer than normal. But look at the outliers: 2004 produced 15 storms including 6 major hurricanes and 4 Florida landfalls during a weak El Niño. And 2023-24 hit 19 storms during a strong El Niño because Atlantic SSTs were extreme. The lesson: El Niño reduces the average but doesn't set the ceiling. One well-placed Category 4 makes a “below average” season devastating.
Hurricane Risk by State: 170+ Years of NOAA Data
Seasonal forecasts tell you how many storms form. They don't tell you where they hit. For that, we have to look at history. NOAA's HURDAT2 database tracks every hurricane landfall since 1851. Three states absorb over 80% of all US hurricane landfalls.
120 hurricanes since 1851 · 37 major (Cat 3+)
Costliest: Hurricane Andrew (1992)
64 hurricanes since 1851 · 19 major (Cat 3+)
Costliest: Hurricane Harvey (2017)
62 hurricanes since 1851 · 18 major (Cat 3+)
Costliest: Hurricane Katrina (2005)
55 hurricanes since 1851 · 7 major (Cat 3+)
Costliest: Hurricane Helene (2024)
30 hurricanes since 1851 · 5 major (Cat 3+)
Costliest: Hurricane Hugo (1989)

2026 US Landfall Probabilities
CSU calculates landfall probability separately from storm counts. These numbers reflect the combined effect of El Niño suppression and the expected storm tracks.
Every region is below its long-term average. The Gulf Coast at 20% vs. 27% average is a meaningful reduction. But for perspective: a 32% chance of a major hurricane landfall somewhere on the US coast is still roughly 1-in-3 odds. You wouldn't get on a plane with those failure rates.
Month-by-Month: When Hurricanes Actually Form
Not all hurricane season months are equal. Here's when the real risk starts, based on 170+ years of NOAA records.
For 2026, El Niño is strengthening through the summer with Niño 3.4 already at +0.9°C. If it follows the development curve models project, August and September — the peak months — will see the maximum suppressive effect. That's the primary reason forecasters are calling below-average major hurricanes: the shear should be strongest exactly when it matters most. June's quiet opening is consistent with this expectation.
How Much Should You Trust April Forecasts?
Honestly? Use them as a general direction, not a precise prediction. CSU's April forecasts correctly identify above-average vs. below-average seasons about 60-70% of the time. But exact storm counts are a different story.
In 2024, CSU's April forecast called for 23 named storms. The actual number was 18 — a miss of 5 storms, but the “above average” call was correct. In 2015, forecasters predicted near-normal activity and got it right thanks to strong El Niño suppression. The forecast CSU issues in June has historically been more accurate because by then, SST patterns are clearer and El Niño strength is more certain.
Season Is Underway — CSU June 10 Update Next
Both NOAA and the season's opening day data confirm the below-normal call. NOAA's May 21 forecast: 8–14 named storms, 55% below-normal. June 1 opened with zero activity and hostile shear across the entire basin. El Niño wind shear is no longer theoretical — it's showing up in real-time satellite imagery. CSU releases its updated June forecast on June 10 with refined SST and shear data from the first days of the season. The key question: with Niño 3.4 at +0.9°C and rising, does the U of Arizona's outlier call of 20 storms hold up? The opening-day evidence says no. NOAA's next update comes in early August ahead of the September peak. We'll update this article when CSU's June forecast drops.
Same El Niño, Different Story: Fewer Hurricanes but a Hotter Summer
The same El Niño that's suppressing hurricane activity is amplifying summer heat across most of the country. NOAA's CPC has 36 states leaning above-normal temperatures. Drought covers 61% of the lower 48. It's the classic El Niño tradeoff: fewer hurricanes, but more heat, more drought, and higher wildfire risk.
