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 heavily favors a Seattle high temperature of 54-55°F (36.5% implied probability) on March 28, closely tracking the latest National Weather Service forecasts indicating daytime highs around 54°F under overcast skies and cool marine air flow from the Pacific. Recent GFS and ECMWF model runs over the past 48 hours have converged on this range, tempering earlier projections of upper 50s amid a strengthening low-pressure system bringing clouds and light precipitation, consistent with Seattle's late-March climatology where average highs hover near 54°F. Lower odds for 52-53°F (25.5%) and 56-57°F (21.5%) reflect ensemble spread capturing uncertainty in boundary layer mixing and potential afternoon clearing, with negligible probabilities above 60°F due to unfavorable upper-air patterns suppressing warming. Watch for NWS updates tomorrow as new observational data refines the outlook.
