Seattle, Washington experiences significant temperature variability in mid-April, typically ranging from 45–55°F during spring. This prediction market focuses on whether the highest temperature recorded on April 18, 2026 will fall within the narrow band of 36–37°F, representing a notably cold day for late spring in the Pacific Northwest. Such temperatures would indicate an unusual cold snap affecting the region. The market is resolvable against official National Weather Service data for Seattle-Tacoma International Airport (SEA), the standard reference point for the city's weather reporting. The 0% current odds indicate traders believe the probability of reaching exactly this temperature range is very low. This could reflect seasonal weather patterns where April temperatures in Seattle typically stay above this threshold, or current forecast data suggesting warmer conditions. The market shows minimal trading volume at $2,900 over 24 hours with modest liquidity of $13,587, typical for narrow daily weather temperature ranges. The odds trajectory will shift based on updated weather forecasts released in the days leading up to April 18. Markets like these help traders assess tail-risk weather scenarios that could impact logistics, agriculture, or event planning across the Pacific Northwest.
