Trader consensus on Polymarket strongly favors a high of 50°F or higher (73.5%) in Seattle on April 18, driven by the latest National Weather Service forecasts and model ensembles from GFS and ECMWF showing daytime highs reaching 59–65°F under a developing upper-level ridge bringing drier, sunnier conditions to the Pacific Northwest. This follows a cooler, showery pattern over the past week with highs in the upper 50s and patchy frost risks, but recent 12Z model runs indicate a warming trend as high pressure builds offshore, suppressing marine clouds typical of Puget Sound influences. Historical April averages hover around 58°F, aligning with the market-implied odds, though 21% on 46–47°F and 19.5% on 44–45°F reflect uncertainty from potential delayed ridge axis or lingering low clouds; watch afternoon NWS updates for refinements ahead of resolution at Sea-Tac Airport.

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 18 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.
