NOAA Predicts Below‑Average 2026 Atlantic Hurricane Season as Strong El Niño Looms
NOAA projects a below-normal 2026 Atlantic hurricane season, forecasting 8–14 named storms, 3–6 hurricanes and 1–3 major hurricanes, largely because a high-probability El Niño is expected to suppress storm activity despite warm sea-surface temperatures in key coastal regions.
Key takeaways
- NOAA forecasts 8–14 named storms, 3–6 hurricanes and 1–3 major (Category 3+) hurricanes for 2026.
- NOAA assigns a 55% chance of a below-normal season, 35% near-normal and 10% above-normal activity.
- NOAA gives a 98% probability that El Niño conditions will be present during the season’s peak.
- Colorado State University’s April forecast projects 13 named storms, 6 hurricanes and 2 major hurricanes, similarly citing El Niño.
NOAA’s outlook and the El Niño signal
The NOAA Climate Prediction Center issued the official 2026 Atlantic hurricane season outlook on Thursday, emphasizing that a developing El Niño in the tropical Pacific is expected to be the primary factor shaping the season. NOAA’s outlook notes that El Niño typically increases upper-level winds over the Atlantic and alters atmospheric patterns in ways that make tropical cyclone formation and intensification less likely. NOAA Ocean Service background material explains the ENSO dynamics in more detail.
Despite forecasted above-average Atlantic sea-surface temperatures — which would ordinarily favor stronger activity — NOAA forecasters concluded the suppressive atmospheric effects tied to a likely El Niño will probably outweigh the warm ocean influence this year. NOAA’s statement frames the net expectation as a below-normal season unless timing or strength of El Niño differs.
How NOAA quantifies the outlook
NOAA framed its forecast using probability bands and point ranges. The agency assigned a 55% chance of below-normal activity and provided ranges for named storms, hurricanes and major hurricanes. NOAA’s forecast for Accumulated Cyclone Energy (ACE) spans 45%–115% of the seasonal median, reflecting wide uncertainty in storm intensity and duration. NOAA Climate Prediction Center materials describe the methodology and confidence ranges in detail.
NOAA also emphasized that the timing of El Niño’s full establishment during the summer will influence how much of the August–October peak is affected, which contributes significantly to the numerical uncertainty. For context on ENSO impacts, see the NOAA/NWS explanation.
Why El Niño matters for the Atlantic
El Niño is the warm phase of the ENSO cycle, defined by sustained higher-than-average sea-surface temperatures across the central and eastern tropical Pacific. Those ocean changes drive atmospheric shifts — including stronger upper-level winds and changes in trade winds — that can disrupt the conditions tropical storms need to form and intensify in the Atlantic basin. See Climate.gov’s ENSO overview and the NOAA Ocean Service ENSO factsheet for background.
Historically, strong El Niño years correlate with fewer Atlantic named storms and hurricanes, while producing more activity in the eastern and central Pacific — a pattern NOAA’s outlook aligns with.
Comparing NOAA and Colorado State University forecasts
NOAA’s outlook broadly agrees with Colorado State University’s April forecast, though CSU’s early-season numbers are slightly more active (13 named storms, 6 hurricanes, 2 major hurricanes). Both groups cite El Niño as a dominant factor and caution that a below-average season can still produce single, highly damaging storms.
Methodological note: NOAA uses probabilistic bands tied to historical activity and ENSO projections, while CSU’s approach emphasizes model output and analog years. Both stress preparedness despite seasonal expectations.
Timing, uncertainty and why preparation still matters
“A below-average outlook does not mean no hurricanes.” Even a single landfalling hurricane can have outsized impacts.
Seasonal forecasts are not event forecasts. NOAA and others warn that storms can form close to land with short lead times, particularly in the eastern Caribbean or Gulf of Mexico. Uncertainty comes from when/how strongly El Niño develops, Atlantic sea-surface temperature patterns, the West African monsoon behavior, and short-term weather disturbances that seed tropical cyclones. See NOAA’s outlook and the NOAA/NWS ENSO explainer for details.
Reporting and attribution notes
The 2026 NOAA hurricane season outlook was issued by the NOAA Climate Prediction Center and the National Weather Service. Background on ENSO influences is available from the NOAA Ocean Service and Climate.gov. Media reporting on CSU’s forecast is available at Fox Weather.
Implications for the United States
Economic: A below-average season would likely reduce aggregate storm-related losses compared with a busier year, but a single major landfall can still cause tens of billions in damage. Insurance markets, coastal businesses, fisheries and shipping may see varied impacts depending on storm tracks.
Political: Leaders at all levels will be judged on preparedness and response if damaging storms occur. A quieter season can ease immediate pressure, but durable planning and funding for coastal defenses remain important.
Social and cultural: Vulnerable communities remain at highest risk; local memory of past storms shapes preparedness attitudes, and clear public messaging is critical to avoid complacency.
Practical applications for households and officials
- Households: Review and update evacuation plans and emergency kits now — not at the last minute. NOAA guidance recommends early preparation.
- Businesses and ports: Inspect infrastructure, review insurance and maintain contingency funds.
- Emergency managers: Keep surge response teams, shelter plans and public information channels ready to operate quickly.
- Policymakers: Maintain disaster funding and support resilience projects to reduce long-term costs from occasional catastrophic storms.
