National Weather Service forecasts for San Francisco International Airport and downtown stations point to a peak near 72°F today under mostly sunny conditions and moderate onshore westerly flow, which aligns with the market's leading 72-73°F bracket. Persistent marine layer influence from the Pacific keeps coastal highs well below inland values, consistent with August climatology averaging around 69°F. Recent model runs show minimal warming potential as sea breezes strengthen through the afternoon, limiting upside to the 74-75°F range while making sub-70°F outcomes less likely absent unexpected cloud cover or stronger advection. Official observations will resolve the market once the daily maximum is recorded.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the San Francisco International Airport Station in degrees Fahrenheit on 23 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=ksfo
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.National Weather Service forecasts for San Francisco International Airport and downtown stations point to a peak near 72°F today under mostly sunny conditions and moderate onshore westerly flow, which aligns with the market's leading 72-73°F bracket.
