**Current forecasts from the National Weather Service and other models indicate a low near 57–58°F for San Francisco on September 21, 2026, driven by persistent marine layer influence and onshore westerly flow typical of mid-September.** This setup maintains overnight cloud cover and moderate humidity, preventing significant radiational cooling while keeping daytime highs in the mid-60s. The implied probability concentration around 58–59°F reflects model consensus on these conditions, with nearby bins (56–57°F and 60–61°F) capturing minor variations from forecast uncertainty or exact measurement timing at official stations. Historical averages place the date’s normal low at about 55.7°F, but recent patterns show slightly milder readings amid stable atmospheric conditions. No incoming troughs or offshore winds are expected to alter the range before resolution.

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 21 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.**Current forecasts from the National Weather Service and other models indicate a low near 57–58°F for San Francisco on September 21, 2026, driven by persistent marine layer influence and onshore westerly flow typical of mid-September.**
