Will the highest temperature in Seattle be between 68-69°F on April 28? Market trades at 0% YES odds, pricing this narrow range as unlikely.
This market has been archived. Historical content preserved below.
Seattle weather markets track daily high temperatures with precision. April 28, 2026 falls in late spring, when Seattle typically experiences mild, moderate conditions. The 68-69°F range represents a specific narrow band that may feel slightly warm compared to Seattle's typical April average of 58-62°F. The current 0% YES odds signal that traders believe this exact temperature window is unlikely to occur on April 28. National Weather Service forecasts and historical patterns for late April suggest a higher probability of temperatures either falling below this range (typical for Seattle) or exceeding it on warmer days. The market reflects accumulated trader conviction that the high temperature will fall outside the 68-69°F band. This type of precision temperature market requires both accurate weather forecasting and real-time market adjustments as forecast models update. Resolution depends on official National Weather Service reporting from Seattle-Tacoma International Airport.
Seattle's climate in late April is characterized by spring transition patterns, where the city gradually shifts from cooler, wetter conditions toward warmer, drier summer weather. The 68-69°F range sits above typical April averages (58-62°F) but well below peak summer highs. Understanding why traders have priced this outcome at 0% requires examining multiple atmospheric and statistical factors. Historically, Seattle's late-April high temperatures cluster around 58-63°F, with the distribution showing that 68-69°F represents an unusually warm outcome for the calendar date. Current atmospheric patterns and the specific weather systems affecting the Pacific Northwest on April 28 become critical variables determining the actual outcome. If high-pressure systems dominate the region on April 28, temperatures could spike above 70°F, overshooting the narrow range entirely. Clear skies and continental air masses would push highs upward. Conversely, if frontal systems bring cloud cover and cooler maritime air from the Pacific, highs may remain in the 55-65°F zone. The 0% odds indicate traders' collective judgment that both scenarios are currently more probable than the precise 68-69°F outcome. The precision required to land exactly in this one-degree band matters significantly. Temperature markets typically show that outcomes cluster around 5-10 degree ranges far more often than narrow 1-degree windows. This reflects both meteorological variability and the mathematical reality of probability distributions. April 28 sits during a period when Seattle's weather remains notably variable day-to-day. The convergence of multiple factors—Pacific Ocean water temperatures, upper-atmosphere jet stream positioning, high and low-pressure system interactions—creates inherent forecast uncertainty even 24-48 hours out. Trader conviction at 0% reflects both this fundamental uncertainty and the base-rate probability that narrow temperature bands face. On any given April day in Seattle, the possible highs can span 20-30 degrees depending on conditions. The 68-69°F range represents just one potential outcome in that broad distribution. Recent Pacific Northwest weather patterns suggest temperatures either cluster in the cool zone (55-65°F) when maritime air dominates, or jump significantly warmer (70-75°F) when continental systems move in. The 68-69°F zone occupies a transition area that occurs less frequently than either end of the distribution. This market exemplifies how weather trading combines meteorological understanding with probabilistic reasoning about temperature distributions and base-rate expectations.
Market resolves YES if National Weather Service reports Seattle's daily high temperature between 68-69°F (inclusive) on April 28, 2026. Resolution occurs on April 29 based on official NWS data from Seattle-Tacoma International Airport.
