Trader consensus on Polymarket overwhelmingly favors 50°F or higher (99.6%) for Seattle's highest temperature on April 18, backed by the National Weather Service's point forecast for Seattle-Tacoma International Airport (KSEA) projecting a high near 63°F under mostly cloudy skies. This positioning stems from recent forecast model consensus—GFS and ECMWF runs—showing a weak high-pressure ridge building over the Pacific Northwest after a brief cool spell with frost advisories through midday April 17, promoting daytime warming. Seasonal climatology reinforces this, with April 18 average highs around 60°F and historical lows above 50°F in 99% of cases. Realistic challenges include a sudden influx of cool marine stratus or accelerated offshore upper low, potentially suppressing peaks to the upper 40s, though model agreement deems this improbable. Monitor NWS updates this afternoon for refinements.

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.
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 overwhelmingly favors 50°F or higher (99.6%) for Seattle's highest temperature on April 18, backed by the National Weather Service's point forecast for Seattle-Tacoma International Airport (KSEA) projecting a high near 63°F under mostly cloudy skies. This positioning stems from recent forecast model consensus—GFS and ECMWF runs—showing a weak high-pressure ridge building over the Pacific Northwest after a brief cool spell with frost advisories through midday April 17, promoting daytime warming. Seasonal climatology reinforces this, with April 18 average highs around 60°F and historical lows above 50°F in 99% of cases. Realistic challenges include a sudden influx of cool marine stratus or accelerated offshore upper low, potentially suppressing peaks to the upper 40s, though model agreement deems this improbable.
