Recent forecasts from the National Weather Service and other models indicate overnight lows near 58–59°F for San Francisco on September 20, aligning with the market's leading 51% implied probability for that range. A redeveloping marine layer, sustained by the cold California Current and coastal upwelling, maintains cool, moist air onshore amid a moderate pressure gradient from inland warming. Westerly winds and increasing cloud cover limit radiative cooling overnight, keeping minimum temperatures above the long-term September average low of about 56°F. Model consensus shows little deviation expected through the weekend, with resolution hinging on the precise timing of marine layer depth and any localized clearing.

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 forecasts from the National Weather Service and other models indicate overnight lows near 58–59°F for San Francisco on September 20, aligning with the market's leading 51% implied probability for that range.
