NOAA predicts below‑average 2026 Atlantic hurricane season as El Niño gains strength
NOAA forecasts a below‑average 2026 Atlantic hurricane season, citing a developing El Niño expected to increase wind shear and suppress storm formation despite warmer Atlantic waters. Officials urge coastal communities to remain prepared for potential major impacts.
- Forecast: NOAA expects 8–14 named storms, 3–6 hurricanes, and 1–3 major hurricanes in 2026, below the 1991–2020 averages.
- Probability: About a 55–70% chance the Atlantic season will be below normal.
- Driver: A developing El Niño is likely to increase Atlantic wind shear and suppress storm formation, despite warmer Atlantic sea‑surface temperatures.
- Watchfulness: Even a below‑average season can produce a devastating landfall; preparedness remains essential.
Main story
NOAA’s 2026 outlook and what the numbers mean
NOAA’s official 2026 Atlantic hurricane outlook calls for 8–14 named storms, 3–6 hurricanes and 1–3 major hurricanes. These ranges sit below the 1991–2020 averages of ~14 named storms, 7 hurricanes and 3 major hurricanes. NOAA attaches a ~55–70% probability that the season will be below normal — a probabilistic outlook that underscores uncertainty and the need for local preparedness. NOAA briefing
Why NOAA expects a quieter Atlantic: El Niño vs. warm Atlantic
NOAA’s seasonal briefing emphasizes a clash of influences: Atlantic sea‑surface temperatures are warmer than average, which typically fuels storms, while a developing El Niño in the tropical Pacific is expected to increase upper‑level winds and vertical wind shear over the Atlantic, tearing apart nascent storms and suppressing hurricane formation. ENSO background (NOAA Climate.gov) and how El Niño and La Niña affect weather (NOAA WPC) explain these mechanisms in detail.
NOAA says the expected El Niño is likely strong enough to “win” over the warmer Atlantic this year, reducing overall Atlantic activity.
How ENSO affects hurricanes
ENSO (El Niño–Southern Oscillation) phases influence global winds and sea temperatures. El Niño—warmer central/eastern tropical Pacific waters—tends to increase Atlantic wind shear and suppress Atlantic hurricanes while enhancing eastern/central Pacific activity. La Niña does the opposite, often producing more active Atlantic seasons. NOAA’s Climate Prediction Center monitors these signals and their strengths; see CPC ENSO strength and impacts for details.
Comparing NOAA and Colorado State University outlooks
Colorado State University’s April forecast aligns with NOAA’s quieter outlook, calling for 13 named storms, 6 hurricanes and 2 major hurricanes — CSU’s lowest early forecast since 2019. Both agencies weigh ENSO signals and Atlantic conditions heavily. NOAA briefing referenced CSU’s April outlook during media remarks.
Eastern and central Pacific outlooks: a different picture
El Niño’s flip side: NOAA expects the eastern and central Pacific to be more active than usual — a typical El Niño signature. The eastern Pacific forecast calls for 15–22 named storms, 9–14 hurricanes and 5–9 major hurricanes, while the central Pacific could see 5–13 tropical cyclones. NOAA briefing
Timing matters: when El Niño locks in
Forecasters emphasize timing: if El Niño strengthens early, suppression may affect much of the June–November season; if it arrives later, early summer could be closer to normal with suppression focused on the peak months (August–October). This timing uncertainty is a key reason NOAA provides ranges and probabilities rather than absolute counts.
Climatology and practical reminders
The official Atlantic hurricane season runs June 1–November 30. Historically, the first named storm forms around June 20 and the first hurricane around August 11. Seasonal outlooks are planning tools — they do not replace local watches, warnings or evacuation orders. For immediate advisories consult the National Hurricane Center.
Uncertainty and limits of seasonal forecasts
NOAA stresses limitations: ENSO forecasts can shift, atmospheric responses vary, and other factors — such as Atlantic Multidecadal Variability or the subtropical high — can alter activity. Observational gaps and scientific uncertainty mean probabilities, not guarantees. Stay informed as forecasts are updated. Season totals do not determine landfall location or local impacts.
Implications for the world
Economic impact
A below‑average Atlantic season could reduce direct storm losses in parts of North America, the Caribbean and overseas territories, but impact depends on landfall location. A single major hurricane striking key ports, cities or energy infrastructure can ripple through global supply chains and insurance markets.
Political consequences
Governments may face scrutiny over preparedness and response regardless of season totals. A busy eastern Pacific could shift humanitarian needs and bilateral support toward Mexico and Central America, testing foreign aid and diplomatic coordination.
Social effects and cultural relevance
Communities should not relax because of a below‑average forecast. Evacuation plans, emergency kits and communications must be tested. Forecasts also inform fisheries, tourism and festival planning in coastal and island communities where cultural ties to seasonal weather are strong.
Practical applications
Prepare now: check local emergency plans, update kits, secure property and review evacuation routes. Seasonal outlooks are for planning; for immediate watches and warnings, follow national meteorological services and the National Hurricane Center.
