Official National Weather Service forecasts for Seattle on August 27 point to gradual morning clearing under southwesterly flow, supporting a daily high near 73°F amid typical marine moderation and seasonal norms around 75°F. Recent model runs and observations from the prior day’s warmer conditions (mid-70s to low-80s) indicate cooling as onshore winds strengthen and cloud cover lingers early, limiting peak solar heating. This aligns with trader consensus favoring the 72-73°F and 70-71°F brackets, reflecting high confidence in sub-75°F outcomes given the absence of offshore flow or strong ridging that could push temperatures higher. Updated NWS briefings and real-time observations will refine exact maxima as the day progresses.

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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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.
