**Incoming anomalous warmth aloft is the main driver positioning 88–91°F as the leading outcomes for Seattle’s June 15 high.** National Weather Service discussions and ECMWF model runs show 850 mb temperatures 14–16°C above normal over the Puget Sound region, supporting surface highs near 90–92°F at SeaTac and elevating the chance of breaking the 88°F daily record set in 1963. Short-term forecasts cluster in the upper 80s to low 90s, with the 7-day NWS point forecast at 87°F reflecting some moderation from increasing clouds or onshore flow. Trader consensus (44.5% for 88–89°F, 28.5% for 90–91°F) reflects this narrow uncertainty band, while lower probabilities for 92°F+ or sub-86°F account for model spread and potential timing shifts in the ridge. Updated NWS guidance and morning model runs on June 15 will provide the final resolution data.

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 15 Jun '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Seattle-Tacoma International Airport Station, 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 until the first data point for the following date has been published on the resolution source.
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.
