Trader consensus on Polymarket favors a Seattle high temperature of 50-51°F at 28.5% implied probability for March 29, closely followed by 48-49°F (22%) and 52-53°F (21%), reflecting tight forecast model spreads amid mild Pacific Northwest spring conditions. The National Weather Service's latest guidance shows highs clustering in the upper 40s to low 50s under weak high-pressure ridging and light onshore flow, with recent 12Z GFS and ECMWF runs converging after yesterday's updates that tempered earlier warmup signals from transient upper-level warming. Key differentiators include timing of morning marine layer burn-off—faster clearance boosts toward 52°F, persistent clouds cap at 48°F—and small-scale diurnal variations typical for Seattle's coastal climatology, where March averages hover near 54°F. New observational data from Sea-Tac soundings and evening NWS forecast discussions could shift odds further before resolution.

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.
