This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Seattle-Tacoma International Airport Station in degrees Fahrenheit on 30 Aug '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=ksea This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button. If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F. 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. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
Persistent marine layer influence and limited solar heating are keeping the highest temperature in Seattle on August 30 tightly contested between the 68–69°F and 70–71°F ranges at the Seattle-Tacoma International Airport station. Official forecasts from the National Weather Service and other models project a high near 69°F, with morning cloud cover gradually giving way to partial afternoon clearing under light southerly to calm winds. This setup reflects typical late-summer onshore flow that advects cooler, moister Pacific air, capping daytime warming below the seasonal average of roughly 75°F. Residual moisture from prior showers further stabilizes the boundary layer, reducing the potential for stronger insolation and higher peaks. The near-even split in market-implied odds between the two leading bins captures genuine forecast uncertainty around the precise timing and extent of clearing, as small differences in cloud dissipation or wind patterns can shift the daily maximum by 1–3°F. Historical analogs for similar marine-influenced days in late August show comparable clustering in the upper 60s to low 70s, reinforcing why traders assign minimal probability to outcomes outside this narrow window. Newer model runs or real-time observations later today could refine the resolution toward one bin or the other.
