Strong El Niño conditions are sustaining elevated vertical wind shear across the tropical Atlantic and Caribbean, inhibiting tropical cyclogenesis and intensification even as sea surface temperatures remain supportive. As of September 10, 2026, the basin has produced multiple named storms but zero hurricanes, approaching the satellite-era record for the latest first hurricane formation around September 11. NOAA’s August outlook assigns a 75% probability of a below-normal season overall (2–6 hurricanes), while Colorado State University’s early September two-week forecast strongly favors continued low activity through mid-month due to persistent shear and dry air. These factors underpin the market’s 55% implied probability of no Atlantic hurricane forming in September, with only modest odds assigned to late-month development. Traders are monitoring upcoming National Hurricane Center outlooks and dynamical model runs for any relaxation in shear that could allow rapid organization.

A tropical cyclone is considered a hurricane when it has maximum sustained winds of 74 mph or greater (Category 1 or higher on the Saffir-Simpson Hurricane Wind Scale). A system is considered to have "formed" as a hurricane at the date and time of the first NHC public advisory that classifies a system in the Atlantic basin as a hurricane. Resolution is based on that first advisory, regardless of any later downward revision or reclassification. The sole determinant of when the hurricane formed is the issuance timestamp of that first classifying NHC advisory (evaluated in U.S. Eastern Time), not the estimated time at which the system's winds first reached 74 mph; for a system that straddles midnight between September 30 and October 1, 2026, the applicable bracket is determined solely by whether that advisory's issuance timestamp falls before or after 12:00 AM ET on October 1, 2026.
The bracket "No Atlantic hurricane will form in September 2026" will resolve "Yes" if no NHC advisory classifies any Atlantic-basin system as a hurricane at any time from 12:00 AM ET on September 1, 2026 through 11:59 PM ET on September 30, 2026. In the event that the NHC has not published any data by September 30, 2026 11:59 PM ET, or if the NHC becomes unavailable, this market will resolve to "No Atlantic hurricane will form in September 2026".
