**Official forecasts from the National Weather Service and supporting models point to an overnight low in the upper 50s for San Francisco on September 21, with most guidance centering on 57–58°F.** Persistent marine influence from the Pacific, light southwest winds of 5–15 mph, and extensive low-level cloud cover are limiting radiational cooling and keeping temperatures from dropping further. This aligns with the recent pattern of mild September conditions, where average lows hover near 56°F and recent nights have bottomed out in the upper 50s. The closely matched market odds around 58–59°F and the 51°F-or-below bucket reflect trader focus on whether the minimum clears the upper-50s threshold or dips modestly lower amid minor model spread and local microclimate variations at official reporting stations. Clearer skies or stronger offshore flow could push readings lower, while sustained onshore flow would support the higher end of the range.

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.**Official forecasts from the National Weather Service and supporting models point to an overnight low in the upper 50s for San Francisco on September 21, with most guidance centering on 57–58°F.** Persistent marine influence from the Pacific, light southwest winds of 5–15 mph, and extensive low-level cloud cover are limiting radiational cooling and keeping temperatures from dropping further.
