This market will resolve to the temperature range that contains the highest temperature recorded at the Seattle-Tacoma International Airport Station in degrees Fahrenheit on 30 Mar '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Seattle-Tacoma International Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/us/wa/seatac/KSEA. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C. This market can not resolve to "Yes" until all data for this date has been finalized. The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). Thus, this is the level of precision that will be used when resolving the market. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Trader consensus on Polymarket reflects razor-thin uncertainty in Seattle-Tacoma International Airport's (KSEA) high temperature today, with NWS forecasts calling for a peak near 50°F under mostly sunny skies following morning lows near 32°F. Observations through late afternoon confirm a brief 50°F at 3:45–3:50 PM PDT amid gradual diurnal heating, but lingering marine influence and potential stratus clouds have capped rises, keeping recent readings at 48–49°F. Differentiating factors include boundary layer mixing efficiency, exact timing of peak insolation before 7:36 PM sunset, and subtle model divergences on afternoon wind shifts; the 48–49°F outcome gains traction if cooling persists, while 50–51°F holds if a final pulse occurs. Final NWS data release post-midnight will resolve.
