Every year, hurricane season delivers a familiar mix of forecasts, watches, warnings, and reminders. 2026 is shaping up to follow a slightly different script than recent years. Forecasters are calling for a below-average season driven by expected El Niño conditions, but the same warning that always accompanies these forecasts applies just as forcefully this year: it only takes one storm to create devastating flood damage.
Here’s what the 2026 outlook looks like and what coastal and flood-exposed property owners should be doing now.
What the Hurricane Season 2026 Forecasts Say
The Atlantic hurricane season runs from June 1 through November 30, 2026. Several major forecasting groups have published outlooks.
Colorado State University’s April forecast calls for:
- 13 named storms
- 6 hurricanes
- 2 major hurricanes (Category 3 or higher)
Tropical Storm Risk, a private British forecasting firm, called for:
- 12 named storms
- 5 hurricanes
- 1 major hurricane
The Weather Channel issued a forecast in April with:
- 12 named storms
- 6 hurricanes
- 2 major hurricanes
North Carolina State University projected a more average season with:
- 12 to 15 named storms
- 6 to 9 hurricanes
The University of Arizona stands out as the most aggressive forecast for the season:
- 20 named storms
- 9 hurricanes
- 4 major hurricanes
- An above-average ACE index, citing similarities to the 2023 season.
Why Forecasters Are Leaning Below Average
The dominant story in the 2026 outlook is El Niño. According to Colorado State and other forecasting groups, La Niña has ended and neutral conditions have taken hold, with El Niño expected to develop within the next several months. Some long-range models indicate this El Niño could be a so-called “Super El Niño,” with central and eastern Pacific sea surface temperatures running more than two degrees Celsius above average.
El Niño tends to suppress Atlantic hurricane activity by increasing winds in the upper atmosphere over the Atlantic basin. This wind shear disrupts developing storms by tilting them and preventing efficient vertical organization. Even when other ingredients are in place – warm ocean water, moisture, and instability – strong upper-level winds can tear storms apart before they fully strengthen.
CSU’s April analysis noted that wind shear across the tropical Atlantic in 2026 could rank as the second highest since 1981, trailing only the 2015 season. That’s a significant suppressing factor, and it’s why most forecasting groups are leaning toward fewer storms than recent years.
The Catch with “Below Average”
Below-average seasons can still produce devastating storms. The recent past makes this point clearly. The 2025 Atlantic hurricane season was an above-normal season with 13 named storms, 5 hurricanes, and 4 major hurricanes, and three hurricanes – Erin, Humberto, and Melissa – reached Category 5 intensity.
Forecasters consistently emphasize that seasonal totals don’t determine your individual risk. A property in the path of one major hurricane in an otherwise quiet season experiences the same damage it would have in an active season. The forecasts are useful for emergency management agencies, insurance underwriters, and supply chain planners. For an individual property owner, the relevant question is whether you’re prepared for a hurricane to make landfall near you, not how many will form basin-wide.
There’s also forecast uncertainty to account for. CSU forecasters noted that the timing of El Niño’s development plays an almost equal role in how much of the hurricane season is suppressed. If El Niño develops slowly or weaker than expected, the wind shear suppression could be less effective and the season more active than the headline numbers suggest.
What Coastal Property Owners Should Be Doing Now
The most important steps to take before June 1 are the ones that take the longest lead time, because once a storm is in the forecast cone, it’s too late to start ordering hardware.
- Conduct a flood vulnerability assessment of your property
- Identify every ground-level opening that could admit floodwater: doors, garages, loading docks, window wells, basement access points, utility penetrations, and below-grade equipment
- Document the design flood elevation each location needs to be protected against
- Look up your FEMA flood zone designation at the FEMA Flood Map Service Center if you don’t already know it
- Review your existing flood protection hardware
- For deployable flood barriers, inspect gaskets for cracking or compression set, fasteners for corrosion, and overall storage condition
- Run a deployment drill before flood season – time it and identify gaps
- Ensure any staff-dependent deployment plan has a trained backup person in place
If You Don’t Have a Flood Protection System Yet
If your property is in a flood-exposed area and you don’t have any flood mitigation hardware in place, the time to start the conversation is now, not after a hurricane makes landfall.
Custom-fabricated flood barriers typically have a four-to-six-week lead time, and during peak hurricane season, lead times stretch as fabricators work through a surge of demand. The right flood protection solution depends on your property type, your flood exposure, and your operational realities:
- Residential homes in moderate flood zones may be well-served by deployable panel systems on key openings.
- Commercial properties in coastal storm surge zones often need a combination of deployable and passive protection, with documentation supporting FEMA dry floodproofing certification.
- Critical facilities, including hospitals, data centers, utilities, and more, warrant the most rigorous engineering and a layered defense.
Insurance and Documentation
If you don’t already have flood insurance, hurricane season is not the time to get it. Most policies have a 30-day waiting period from purchase to coverage, which means a policy bought in August won’t cover a September storm. Standard homeowners’ and commercial property insurance policies do not cover flood damage. Coverage comes through the National Flood Insurance Program (NFIP) or a private flood insurance carrier.
If you have flood mitigation hardware in place, document it for your insurer. Sealed engineering drawings, FEA reports, certified deployment procedures, and photographs of installed components are all worth providing to your underwriter. Flood mitigation can affect both your insurability and your premium pricing, particularly for commercial properties in higher-risk zones.
The Bottom Line for Hurricane Season 2026
Hurricane season 2026 is forecast to run slightly below average, but “below average” remains an above-zero risk, and the only forecast that matters for your property is the one for the storm that finds your address. Use the relatively quieter outlook as an opportunity to do the preparation work that’s harder to fit in during an active season.
Flood Risk America works with property owners across the globe to design, fabricate, and install flood mitigation systems sized to real-world risk. If you’d like to talk through your property’s flood exposure and what protection options make sense, our team is ready to help.
