The closely matched market odds around 30% for each short-term window or none in August reflect uncertainty in the precise timing of the next Eastern or Central Pacific system reaching sustained 74 mph winds amid an El Niño-boosted season. Abnormally warm sea surface temperatures and reduced vertical wind shear favor rapid organization from current disturbances, including Tropical Storm Hernan and Potential Tropical Cyclone One-C, with NHC and NOAA outlooks noting above-normal activity through peak months. Model runs show variable intensification windows tied to steering patterns and moisture, while the 30% probability of no August hurricane captures the possibility that systems remain below hurricane thresholds or form later, consistent with historical variability in early-to-mid August formation rates. Traders will watch updated NHC 48-hour and 7-day outlooks for shifts in development probability.

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). For this market, the "Pacific" comprises the Eastern Pacific basin and the Central Pacific basin as tracked by the NHC and CPHC. Systems classified as typhoons do not count. A system is considered to have "formed" as a hurricane at the date and time of the first NHC or CPHC public advisory that classifies a system in these basins 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 advisory, not the estimated time at which the system's winds first reached 74 mph; for a system that straddles midnight between August 31 and September 1, 2026, the applicable bracket is determined solely by whether that advisory's issuance timestamp falls before or after 12:00 AM ET on September 1, 2026.
The bracket "No Pacific hurricane will form in August 2026" will resolve "Yes" if no NHC or CPHC advisory classifies any Eastern Pacific or Central Pacific system as a hurricane at any time from 12:00 AM ET on August 13, 2026 through 11:59 PM ET on August 31, 2026.
