NOAA predicts below‑average Atlantic season as strong El Niño looms — what that means for 2026
NOAA’s 2026 Atlantic hurricane outlook forecasts a below‑normal season, driven by an expected strong El Niño that will likely suppress storm formation despite warmer‑than‑average Atlantic waters — fewer named storms, hurricanes and major hurricanes are expected.
Key takeaways
- NOAA’s 2026 Atlantic hurricane season outlook calls for 8–14 named storms, 3–6 hurricanes and 1–3 major (Category 3+) hurricanes, with a 70% chance the season will fall in that range.
- Probabilities: NOAA assigns a 55% chance of a below‑normal season, 35% chance of near‑normal and 10% chance of above‑normal activity (NOAA).
- El Niño likely dominant: A developing El Niño is expected to suppress Atlantic activity even though Atlantic sea surface temperatures are above normal (NOAA; WLRN).
- Independent agreement: Colorado State University’s April outlook reached a similar view with about 13 named storms, 6 hurricanes and 2 major hurricanes, noting a likely “Super El Niño.”
NOAA’s 2026 forecast in detail
NOAA’s official seasonal outlook, issued in May 2026, centers on lower basin‑wide activity than the 30‑year average. The long‑term Atlantic average is about 14 named storms, 7 hurricanes and 3 major hurricanes. NOAA’s projected range of 8–14 named storms and 3–6 hurricanes would place most of 2026 below or near that average. The agency also gives an ACE (Accumulated Cyclone Energy) range of 45–115% of the median, corresponding to below‑normal to near‑normal seasonal energy (NOAA’s outlook).
“This is a basin‑wide activity forecast, not a landfall forecast.” — NOAA warned that a quieter season can still produce a damaging or deadly storm for a particular coast or community (NOAA briefing video).
Why El Niño matters this year
NOAA highlights two competing factors: above‑normal Atlantic sea surface temperatures, which normally favor more storms, versus a strongly developing El Niño, which tends to suppress Atlantic hurricanes through increased upper‑level winds and vertical wind shear. The agency judges El Niño will likely be the stronger influence in 2026 (NOAA; WLRN).
What is El Niño? El Niño is a phase of the El Niño–Southern Oscillation (ENSO) when large stretches of the central and eastern tropical Pacific are warmer than average. ENSO shifts global temperature and wind patterns; during El Niño, upper‑level winds over the tropical Atlantic often strengthen, creating vertical wind shear that tears apart developing storms (NOAA ENSO background; NOAA Ocean Service; NWS summary).
NOAA’s ENSO outlook gives roughly a 98% chance of El Niño during the Aug–Oct peak and about an 81% chance it will be at least moderate strength in August–October, with many models pointing to a strong or very strong event (NOAA ENSO outlook).
How a strong El Niño can shift the seasons
El Niño often produces a basin “seesaw.” While Atlantic activity tends to be suppressed, the Eastern and Central Pacific basins commonly become more active. NOAA’s briefing noted expectations for above‑normal Eastern Pacific activity in 2026, with more named storms and hurricanes due to lower shear and warm Pacific waters (NOAA briefing).
Although current North Atlantic sea surface temperature anomalies are modestly above normal — which would normally help storms — NOAA judges that El Niño’s wind shear effects will likely override that boost for most of the season (NOAA outlook).
CSU outlook and independent agreement
Colorado State University’s April outlook called for about 13 named storms, 6 hurricanes and 2 major hurricanes, and highlighted the odds of a Super El Niño that could be the dominant seasonal influence. CSU’s forecast aligns with NOAA’s view that El Niño will likely reduce Atlantic activity relative to the active era that began in 1995.
Timing, uncertainty and what the outlook does not say
Forecasters emphasize the importance of timing: if El Niño strengthens early in summer, more of the season could be suppressed; if it strengthens later, parts of the season could still be active. Even in strong El Niño years, powerful storms can form and make landfall — seasonal forecasts do not pinpoint where storms will strike (NOAA; NOAA briefing).
Climatological markers: the first named storm typically forms around June 20 and the first hurricane near Aug. 11. Peak activity usually runs from mid‑August through late September (NOAA seasonal norms).
Risk message and preparedness
NOAA and other forecasters stress: a below‑normal outlook is not a reason to relax preparedness. A single hurricane making landfall can cause major damage. Residents and leaders should use a quieter forecast as an opportunity to check plans, secure insurance, and prepare emergency kits (NOAA guidance; NOAA briefing).

Implications for Fresno, California
Economic impact
Fresno sits far inland, but a strong El Niño often shifts Pacific storm tracks southward, increasing the odds of a wetter winter for central and southern California. For Fresno, wetter winters can replenish reservoirs and help groundwater recovery, easing drought stress for farmers — yet heavy rain can also damage crops and delay planting or harvest, affecting farm income and local food supply (NOAA ENSO overview; NOAA Ocean Service).
Political consequences
Local and state officials may face pressure to manage flood risk, open reservoirs, and coordinate emergency services. A wetter season can create impetus for increased water management funding or accelerated levee and canal projects; conversely, if rains underperform, drought policy debates could intensify in Sacramento and Fresno County.
Social effects
Stronger winter storms raise the risk of flooding, mudslides in foothill areas, and power outages. Low‑income and vulnerable communities may face greater disruption. Authorities should plan for shelters, emergency warming centers and public‑health responses if storms bring prolonged rain or cold snaps.
Cultural relevance
Agriculture is central to Fresno’s identity. El Niño rains can restore hope for growers and communities hit by drought, but unpredictable weather complicates planning for festivals, county fairs and outdoor events. Clear communication from local leaders will help align expectations with evolving forecasts (NOAA ENSO info).
Practical applications for Fresno residents and leaders
- Water and farm managers should use seasonal outlooks to plan reservoir releases and crop schedules while remaining flexible.
- Emergency managers should review flood maps, clear storm drains, and coordinate messaging and shelter capacity with state partners.
- Households should secure gutters, check roofs, and prepare basic emergency kits with food, water and medicine — a quiet Atlantic season does not reduce Pacific storm risk.
- Farmers and orchard managers should consult local extension services for timing and crop advice tied to forecast changes.
Bottom line: Use NOAA’s 2026 outlook as one planning input among many. While the Atlantic may be quieter, a strong El Niño raises the odds of a wetter Pacific season — bringing both relief and new risks to California’s Central Valley (NOAA outlook; NOAA ENSO).
