Recent National Weather Service and model consensus points to a San Francisco overnight low in the upper 50s for August 21, 2026, driven by persistent marine-layer stratus and moderate west-northwest winds that limit radiational cooling. Typical August climatology yields an average low near 56 °F, with the current forecast range of 56–58 °F reflecting stable onshore flow and elevated dew points around 55 °F that suppress further temperature drops. Traders have priced the 58–59 °F bin highest because ensemble guidance shows little deviation from this narrow band absent an unexpected clearing or stronger gradient. Upcoming NWS updates and any shift in 500-mb heights will determine whether probabilities migrate toward the adjacent 54–55 °F or 60–61 °F outcomes.

This market will resolve based on the lowest 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 lowest 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 lowest 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.
