Recent National Weather Service and ensemble model guidance indicates San Francisco's overnight low on September 20 will settle in the upper 50s under persistent marine-layer stratus and moderate onshore flow from the Pacific. This setup, reinforced by a weak trough and typical September climatology, suppresses radiative cooling while preventing stronger offshore warming, keeping minimum temperatures near the 1991–2020 average of 55.8 °F. With the market heavily weighted toward the 56–57 °F bin, traders are pricing the high probability that official observations at downtown or airport stations will resolve in that narrow range rather than testing the historical record low of 50 °F.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the San Francisco International Airport Station in degrees Fahrenheit on 20 Sep '26.
The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=ksfo
This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button.
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.Recent National Weather Service and ensemble model guidance indicates San Francisco's overnight low on September 20 will settle in the upper 50s under persistent marine-layer stratus and moderate onshore flow from the Pacific.
