Trader consensus heavily favors a highest temperature of 76-77°F on August 11 in San Francisco, reflecting National Weather Service observations and regional model runs that captured peak afternoon readings under moderating onshore flow. A persistent marine layer and cool Pacific advection typically suppress highs near 70°F in August, yet localized warming from reduced cloud cover and lighter winds allowed temperatures to reach the mid-70s at official stations. This outcome aligns with climatological variability around the seasonal mean of roughly 69-72°F. Resolution hinges on verified maximums from primary reporting sites; alternative scenarios such as station-specific discrepancies or post-analysis revisions remain possible but low-probability given consistent data streams.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the San Francisco International Airport Station in degrees Fahrenheit on 11 Aug '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 San Francisco International Airport Station, available here: https://www.wunderground.com/history/daily/us/ca/san-francisco/KSFO.
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.
