Recent National Weather Service and ensemble forecasts position the lowest temperature in San Francisco on September 21 near 58°F, driven by persistent onshore westerly flow and marine layer influence that moderates overnight cooling along the coast. A cutoff low moving into the region has interrupted a prior warming trend, producing mid-to-upper 50s lows in model runs for Monday night amid mostly cloudy conditions and light southwest winds. This aligns with the historical average low of 55.7°F for the date while remaining above record minima near 51°F. Traders appear to weigh these stable coastal dynamics against minor model spread in dew points and cloud cover, with final NWS updates and any late adjustments to the marine layer expected to refine probabilities 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.Recent National Weather Service and ensemble forecasts position the lowest temperature in San Francisco on September 21 near 58°F, driven by persistent onshore westerly flow and marine layer influence that moderates overnight cooling along the coast.
