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 5 Apr '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 prices a mid-60s°F high in Seattle on April 5 at over 65% combined implied probability for 64-67°F outcomes, driven by the National Weather Service's latest guidance showing partly sunny skies and highs near 64°F following a cool, rainy pattern earlier this week with 50°F peaks. Upper-air analyses reveal a developing ridge aloft promoting subsidence and reduced marine layer influence from Puget Sound, allowing greater solar heating amid light winds. Differentiating the close 64-65°F (36%) and 66-67°F (29.5%) leaders hinges on model spread in GFS and ECMWF ensembles regarding low cloud persistence and boundary layer mixing—lingering stratus could cap at 64°F, while earlier clearing pushes toward 67°F. New runs expected overnight may sharpen this; resolution uses official Seattle-Tacoma International Airport (KSEA) measurement.
