Seattle experiences variable spring weather in mid-to-late April, with typical daytime highs ranging from 45 to 60 degrees Fahrenheit depending on active weather systems and atmospheric patterns. This prediction market focuses on whether the highest temperature recorded in Seattle on April 20, 2026 will fall within the narrow and specific 48-49°F range. Currently trading at 0% YES odds, the market indicates strong consensus among traders that the actual high temperature will fall outside this target band, either significantly warmer or considerably cooler. The zero-odds pricing suggests traders expect April 20 to feature either typical spring warmth pushing into the low-to-mid 50s, or a cool weather system holding temperatures in the low 40s. The market resolves based on official National Weather Service data recorded at Seattle-Tacoma International Airport, the standard weather station for the city. With trading volume of $2,710 and available liquidity of $14,458, the market has moderate activity for a daily temperature prediction. The current pricing reflects both seasonal weather patterns and any available extended forecast models for that specific date. This narrow 48-49°F range represents an unusually precise weather target, which explains the market's extremely bearish odds.
