Persistent onshore flow and a stable marine layer continue moderating San Francisco temperatures, with National Weather Service guidance forecasting a high near 69°F on August 21 under partly sunny skies. This aligns with the August climatological average of 67–68°F at official stations, where sea breezes and low stratus frequently cap afternoon warming. Model consensus shows limited potential for stronger offshore winds or subsidence that could push readings into the low 70s, while cooler scenarios remain possible if the marine layer deepens overnight. Trader consensus therefore clusters around the 68–71°F brackets, reflecting both the narrow historical range for late-August highs and the absence of anomalous synoptic patterns in the latest forecast updates.

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.
