Persistent marine layer influence and onshore westerly winds from the Pacific are expected to cap highs in San Francisco on August 21, consistent with the market-implied clustering around 68–71°F. Recent NWS observations show mid-August daily maxima in the mid- to upper-60s amid frequent low stratus and fog, aligning with climatological normals near 69°F and the absence of offshore flow or ridging that would allow warmer interior air to reach the coast. Short-range model consensus favors mostly cloudy conditions with highs near 65–68°F, limiting upside risk above 72°F while keeping sub-66°F outcomes less probable under typical August solar heating. Traders appear to be weighting these stable cool-summer dynamics against minor forecast variability in marine layer depth.

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 21 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.
