Trader consensus on Polymarket shows a 100% implied probability for Seattle's highest temperature on March 29 falling in the 46-47°F range, directly anchored by official observations at Seattle-Tacoma International Airport (KSEA), the primary reporting station, which recorded a maximum of 46°F around 1 PM local time. Cloudy conditions with light rain totaling 0.1 inches suppressed daytime heating, aligning with forecast model consensus from NOAA's National Weather Service that anticipated cool, overcast weather under a persistent marine layer typical for late March in the Pacific Northwest. Seasonal normals hover around 54°F, but persistent cloud cover and cool air advection from the Pacific kept readings well below average. With verified data now finalized, scenarios challenging this outcome—such as rare post hoc measurement revisions—are negligible, as preliminary reports rarely change.
