NOAA predicts below‑average 2026 Atlantic hurricane season as strong El Niño builds — what that means for coasts and local preparedness
NOAA’s May outlook forecasts a 55% chance of a below‑normal 2026 Atlantic hurricane season as a strong El Niño is expected to suppress storm formation, despite warmer‑than‑average Atlantic sea‑surface temperatures and NOAA provides storm-count ranges and probabilities for coastal preparedness.
Key takeaways
- NOAA outlook: 55% chance of a below‑normal Atlantic season; forecast ranges (70% probability) of 8–14 named storms, 3–6 hurricanes, 1–3 major hurricanes. See the NOAA 2026 Atlantic Hurricane Season Outlook.
- El Niño is dominant: Forecasters give a very high chance El Niño will be present and likely moderate or stronger during the August–October peak, which typically suppresses Atlantic activity.
- Pacific activity up: El Niño shifts activity eastward, increasing Eastern and Central Pacific risk (impacts for Mexico, Central America, Hawaii and California).
- Local implications: Southern California coasts like Huntington Beach should prepare for larger surf, coastal erosion and episodic heavy rain even if the Atlantic basin is quieter overall.
NOAA’s May outlook and probabilities
The National Oceanic and Atmospheric Administration’s official May outlook assigns a 55% chance of a below‑normal 2026 Atlantic season, 35% near‑normal and 10% above‑normal. NOAA gives forecast ranges (70% probability) of 8–14 named storms, 3–6 hurricanes, and 1–3 major hurricanes. For full details consult the NOAA 2026 Atlantic Hurricane Season Outlook.
Why NOAA expects a below‑average Atlantic season
NOAA frames 2026 as a tug‑of‑war between two main signals: a developing, likely strong El Niño in the tropical Pacific and modestly warmer‑than‑average Atlantic sea‑surface temperatures. Forecasters say El Niño is likely to “win.” NOAA places a 98% chance that El Niño conditions will be present during the Atlantic season and an 81% chance those conditions will be moderate or stronger during the August–October peak.
How El Niño suppresses Atlantic storms
Scientists document several atmospheric changes linked to El Niño that typically reduce Atlantic hurricane activity:
- Increased vertical wind shear: Strong upper‑level winds across the tropical Atlantic can tear apart developing storms before they strengthen.
- Reduced convective buoyancy: El Niño shifts deep convection eastward into the central and eastern Pacific, starving the tropical Atlantic of the heat‑and‑moisture bursts that feed storms.
- Shift in tropical rainfall and storm locus: The Pacific becomes the favored zone for storm development, boosting Eastern Pacific activity while suppressing the Atlantic.

Competing factor: warm Atlantic waters
Atlantic sea‑surface temperatures are modestly above average (about +0.27 °C across parts of the basin) and are expected to remain above normal through August–October, which normally favors storm formation and intensity. NOAA analysts judge the likely El Niño strong enough to offset these warm ocean signals.
How NOAA’s numbers compare with Colorado State University
Colorado State University (CSU) issued an April forecast calling for 13 named storms, 6 hurricanes and 2 major hurricanes. That point forecast sits inside NOAA’s ranges and likewise attributes a controlling role to El Niño. See the Fox Weather summary of NOAA and CSU outlooks for CSU’s take.
Timing, uncertainty and the limits of seasonal outlooks
Seasonal outlooks estimate basinwide activity, not landfalls. NOAA’s probabilities—55% below‑normal, 35% near‑normal, 10% above‑normal—reflect uncertainty about how quickly Pacific warming couples with atmosphere and how Atlantic conditions evolve. Forecasters emphasize that even in a below‑average season a single powerful storm can cause massive damage.
“A single major hurricane can make landfall in a year when the basin overall is quiet,” NOAA analysts note in briefing materials.
Eastern and Central Pacific expected to be busier
El Niño typically shifts warm water and convection eastward across the tropical Pacific. NOAA’s forecast points to an above‑normal Eastern Pacific season—15–22 named storms, 9–14 hurricanes, 5–9 major hurricanes—and 5–13 tropical cyclones in the Central Pacific. This pattern raises odds of impacts for Mexico, Central America, Hawaii and — indirectly — California through heavier rains, coastal flooding and large surf. See NOAA’s briefing materials including the NOAA briefing video.
“Homegrown” Atlantic storms and coastal risk
Forecasters caution that systems that form close to or over land—so‑called “homegrown” storms—remain a persistent risk. These typically develop in the northern Gulf of Mexico or along the U.S. Southeast coast and can spin up quickly, producing short lead times for warnings and evacuations.

Implications for Huntington Beach, California
Economic impact
Surf and beach economy: A strong El Niño typically brings larger Pacific swells and more offshore storm activity. For Huntington Beach, better surf can boost tourism and local businesses but also create dangerous conditions, reduced beach access after erosion, and higher cleanup costs.
Local business planning: Hotels, restaurants and seasonal vendors should plan for visitor upticks related to surf events and storm watchers as well as temporary closures and infrastructure repairs after high‑energy wave events.
Political consequences
Increased Eastern Pacific activity may shift costs to local government for beach replenishment, storm damage response and public works. Investments in shoreline protection, dune restoration and efficient emergency plans can reduce long‑term costs and may become a local budget priority. Huntington Beach officials may need closer coordination with Los Angeles County, the state and federal agencies for rapid storm response (NOAA Pacific forecast).
Social effects
Remnants of Pacific storms can bring heavy rain and flash flooding to Orange County with shorter lead times than Atlantic hurricanes. Residents should review evacuation routes, property protection measures, and stay alert to county and municipal advisories.
Cultural relevance
Huntington Beach’s surf culture means El Niño’s surf boost will have cultural and economic significance. City leaders and event organizers should balance promotional opportunity with clear safety messaging to protect residents and visitors.
Practical applications for residents
- Prepare property now: Clear drains, trim trees, secure loose items, and review insurance for flood and wind coverage.
- Build an emergency kit: Water, nonperishable food, flashlights, batteries, and copies of key documents.
- Monitor trusted sources: Follow NOAA updates, the National Weather Service, and local county alerts for watches and warnings.
- Know local response plans: Learn county evacuation routes, shelter locations, and sign up for emergency alert systems.
Conclusion
Reporting on the 2026 Atlantic Hurricane Season Outlook highlights a split picture: the Atlantic is likely to be quieter than recent years, but El Niño will lift risk and activity in the Pacific — with direct consequences for Southern California coastlines and local economies. Huntington Beach should prepare for bigger surf, possible coastal erosion and episodic heavy rain while remembering that one storm — Atlantic or Pacific — can rapidly change local risk.
