Trader consensus on Polymarket implies a highest temperature around 60°F in Seattle on April 4, with 60-61°F leading at 36.5% amid tight odds for 58-63°F bins reflecting uncertainty in persistent marine layer stratus from Pacific onshore flow. National Weather Service guidance highlights low-level clouds capping solar insolation over Puget Sound, potentially limiting highs to the upper 50s if the deck endures, versus low 60s with afternoon burn-off under light southerly winds and 20-40% sun breaks. This follows cooler-than-normal early April showers transitioning to NOAA's above-average spring outlook; watch evening model runs and dawn observations for shifts, as short-range forecasts carry inherent variability from boundary layer dynamics. Historical April 4 highs at Sea-Tac average 58°F, underscoring the razor-thin differentiation.

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 4 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 implies a highest temperature around 60°F in Seattle on April 4, with 60-61°F leading at 36.5% amid tight odds for 58-63°F bins reflecting uncertainty in persistent marine layer stratus from Pacific onshore flow. National Weather Service guidance highlights low-level clouds capping solar insolation over Puget Sound, potentially limiting highs to the upper 50s if the deck endures, versus low 60s with afternoon burn-off under light southerly winds and 20-40% sun breaks. This follows cooler-than-normal early April showers transitioning to NOAA's above-average spring outlook; watch evening model runs and dawn observations for shifts, as short-range forecasts carry inherent variability from boundary layer dynamics. Historical April 4 highs at Sea-Tac average 58°F, underscoring the razor-thin differentiation.
