Recent National Weather Service and model forecasts position the overnight low for San Francisco on September 20 in the 56–59°F range, driving the 88.5% market-implied probability for 56–57°F. Persistent marine layer clouds, light west-southwest winds, and typical September coastal moderation have limited radiative cooling overnight, keeping temperatures above the 55.8°F climatological average low. Official guidance shows no significant cold-air advection or clear-sky window that would allow a sharper drop, while historical records for the date indicate 51°F or below occurs infrequently under similar setups. Updated model runs and evening observations continue to support this narrow band ahead of final daily minimum readings.

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 model forecasts position the overnight low for San Francisco on September 20 in the 56–59°F range, driving the 88.5% market-implied probability for 56–57°F.
