About This Event
Central Pacific in 2026 If more than X hurricanes of category 1 or above occur in the Central Pacific between May 15, 2026 and December 01, 2026 as confirmed by the National Weather Service or equivalent national weather service, then the market resolves to Yes. Early close condition: This market will close and expire early if the weather event occurs. This market will close and expire early if the weather event occurs.
Current Market Outlook
Kalshi traders are pricing a 76% chance that more than one Category 1+ hurricane will form in the Central Pacific between May 15 and December 1, 2026. That is a strong yes vote. The market sees multiple hurricanes as the baseline expectation, not a surprise. For context, the Central Pacific averages about four named storms per year, with roughly two reaching hurricane strength. So the market is effectively betting the region will at least meet its historical average.
Key Factors Driving the Odds
The Central Pacific hurricane season is heavily influenced by ENSO conditions. La Niña years suppress hurricane activity in this basin by increasing wind shear and cooling sea surface temperatures. El Niño years do the opposite, reducing shear and warming waters, which often produces more hurricanes. The current consensus from NOAA and other forecast models points toward neutral or weak El Niño conditions developing by mid-2026. That shift alone raises the baseline odds of multiple hurricanes.
Another factor is the 2025 season itself. The Central Pacific saw below-average activity last year, with only one hurricane forming. Traders are likely pricing in a bounce-back effect. Hurricane seasons in this region tend to cluster, with quiet years followed by active ones. The 76% price reflects that pattern.
What Could Change These Odds
The biggest risk to the yes side is a sudden shift to La Niña conditions. If the ENSO outlook flips in early 2026, the probability could drop sharply. The market will also update when NOAA releases its pre-season outlook in May 2026. A forecast calling for below-normal activity would push the price down.
On the flip side, an early-season hurricane in May or June would likely send the price above 90%. The market closes early if the event occurs, so the 76% price already accounts for that possibility. Traders should watch the Madden-Julian Oscillation and sea surface temperature anomalies in the Central Pacific, as these are the near-term drivers that could move the odds before the season starts.

Overview
The Central Pacific hurricane season runs from June 1 to November 30 each year, though storms can form outside those dates. The Central Pacific basin, officially defined as the region between 140°W and 180°W longitude, is monitored by the Central Pacific Hurricane Center (CPHC) in Honolulu, Hawaii. This region typically sees fewer hurricanes than the Atlantic or Eastern Pacific basins due to cooler water temperatures and stronger wind shear. On average, the Central Pacific experiences about 4 to 5 tropical cyclones per year, with 2 to 3 becoming hurricanes. The 2026 season is being watched closely because of the potential influence of El Niño or La Niña conditions, which can significantly alter storm activity. El Niño years tend to bring warmer waters and reduced wind shear, leading to more hurricanes in the Central Pacific, while La Niña years suppress activity. The prediction market asks whether more than a specified number of Category 1 or higher hurricanes will occur between May 15 and December 1, 2026. This timeframe extends slightly beyond the official season to capture early or late storms. The National Weather Service and equivalent agencies in other nations provide the official confirmation of hurricane status. The market will close early if the event occurs, meaning if the threshold is reached before the December 1 deadline, the market resolves immediately. This market attracts interest from meteorologists, disaster planners, insurance companies, and climate researchers, as Central Pacific hurricanes directly threaten Hawaii, Johnston Atoll, and other Pacific islands, as well as shipping and aviation routes. The 2026 season follows a period of heightened activity in the Pacific, with 2023 and 2024 seeing above-average numbers of storms in the basin.
Historical Context
The Central Pacific hurricane season has been officially monitored since 1970, when the CPHC was established. Prior to that, storms were tracked by the Joint Typhoon Warning Center or the Eastern Pacific Hurricane Center. The most active season on record was 2015, which saw 8 tropical cyclones and 5 hurricanes, driven by a strong El Niño. That year, Hurricane Patricia became the strongest hurricane ever recorded in the Eastern Pacific, though it did not directly affect the Central Pacific. The 2015 season also included Hurricane Ignacio, which passed near Hawaii but weakened before landfall. The quietest season was 1977, with only 1 tropical cyclone and no hurricanes, during a La Niña event. The average number of hurricanes per year from 1970 to 2024 is about 2.3. Notable storms include Hurricane Iniki in 1992, a Category 4 that struck Kauai, causing $3.1 billion in damage and 6 deaths. Hurricane Lane in 2018 was a Category 5 that brought record rainfall to Hawaii but stayed offshore. Hurricane Douglas in 2020 came within 30 miles of Oahu as a Category 1. The basin also sees storms that cross from the Eastern Pacific, such as Hurricane Dora in 2023, which passed south of Hawaii and contributed to the Maui wildfires by generating strong winds. The 2024 season had 5 tropical cyclones and 3 hurricanes, slightly above average. Climate change is expected to increase the intensity of hurricanes globally, though the effect on frequency in the Central Pacific is less clear. Warmer sea surface temperatures provide more energy for storms, but changes in wind shear and atmospheric circulation could offset this. The 2026 season will be influenced by the ENSO cycle, which was in a neutral phase in early 2026 but with models showing a potential shift toward El Niño later in the year.
Why It Matters
Central Pacific hurricanes pose a direct threat to Hawaii, which has a population of 1.4 million and a tourism-dependent economy worth $20 billion annually. A hurricane landfall can cause billions in property damage, disrupt air travel, and strain emergency services. The 1992 Hurricane Iniki remains the costliest natural disaster in Hawaii's history, and a similar storm today would cause far greater economic losses due to increased development. Beyond Hawaii, hurricanes in this basin affect military installations, including Joint Base Pearl Harbor-Hickam and the Pacific Missile Range Facility. They also impact shipping lanes between North America and Asia, as well as undersea cables that carry internet traffic. For insurers, accurate hurricane counts help set premiums and reserve funds. For climate researchers, year-to-year variability in hurricane numbers provides data on how the Pacific Ocean is responding to global warming. The prediction market itself reflects growing public interest in weather forecasting and climate risk, as people seek to hedge against or profit from extreme weather events. The outcome of this market could influence how other markets are designed for future hurricane seasons.
Current Status
As of May 2026, the Central Pacific hurricane season has not yet begun, but the pre-season outlook from NOAA is expected in late May. The ENSO conditions are neutral, with sea surface temperatures near average across the equatorial Pacific. Some climate models indicate a possible shift toward El Niño by late summer, which could increase hurricane numbers. No tropical cyclones have formed in the Central Pacific in 2026 as of mid-May. The eastern Pacific has seen one named storm, but it dissipated before crossing into the Central Pacific. The CPHC has conducted its annual training exercises and is ready for the season. The prediction market is open and trading, with the threshold number of hurricanes not yet specified in the market description but likely set at 3 or 4 based on historical averages.
Frequently Asked Questions
How many hurricanes typically form in the Central Pacific each year?
The Central Pacific averages 2.3 hurricanes per year, based on records from 1970 to 2024. The number ranges from 0 to 5, with El Niño years typically producing more hurricanes.
What is the difference between a tropical storm and a hurricane?
A tropical storm has sustained winds of 39-73 mph, while a hurricane has sustained winds of 74 mph or higher. Hurricanes are further classified into Category 1 through 5 on the Saffir-Simpson scale.
When does the Central Pacific hurricane season start and end?
The official season runs from June 1 to November 30. However, the prediction market covers May 15 to December 1 to account for storms that form slightly outside these dates.
How does El Niño affect Central Pacific hurricanes?
El Niño warms the ocean surface and reduces wind shear in the Central Pacific, creating conditions that favor hurricane formation. El Niño years typically see 3 to 5 hurricanes, compared to 1 to 2 during La Niña years.
