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 28 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 National Weather Service forecasts of a high near 55°F in Seattle today under partly sunny skies, following recent rainy and cooler conditions including a record 0.99 inches of rain on March 24 and a 52-53°F high on March 26. GFS and ECMWF ensemble models average 55-57°F amid a weak upper-level ridge promoting drier air and light northerly winds, slightly above the March climatological average of 52°F at Seattle-Tacoma International Airport. The close split between 54-55°F (42.5% implied probability) and 56-57°F (33%) stems from uncertainty in afternoon cloud cover and solar insolation, with ongoing hourly updates and observations at KSEA determining the official peak before resolution.
