Marine layer advection and persistent westerly winds off the Pacific are holding San Francisco's overnight minimum near the upper 50s, consistent with the 56–58 °F range shown in National Weather Service and model guidance. Onshore flow and low-level stratus limit radiational cooling, while the absence of offshore winds or high-pressure subsidence keeps the daily low close to the long-term August average of 55.9 °F. Recent observations from KSFO confirm overnight readings of 56–57 °F under similar conditions, reinforcing trader consensus around the 58–59 °F bin as the most probable outcome before the night concludes.

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.
