Official NWS observations at San Francisco International Airport recorded a minimum of 58°F on August 21, 2026, anchoring trader consensus on the 58-59°F bin while nearby ranges reflect residual uncertainty over exact microclimate readings or verification timing. Typical late-August conditions featured a strong marine layer with onshore flow and coastal fog suppressing overnight radiational cooling, keeping lows near the 1991-2020 normal of 57°F rather than allowing deeper drops seen in drier interior patterns. Model consensus and climatological analogs supported this narrow band, with limited deviation from baseline sea-surface temperatures and wind regimes; markets priced lower outcomes modestly due to potential for localized cooling in the city proper versus the airport station used for resolution.

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.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Official NWS observations at San Francisco International Airport recorded a minimum of 58°F on August 21, 2026, anchoring trader consensus on the 58-59°F bin while nearby ranges reflect residual uncertainty over exact microclimate readings or verification timing.
