**Recent cooling from returning marine influence after a midweek heat wave is the main driver of trader positioning for San Francisco’s September 11 low temperature.** A strong high-pressure ridge brought unusually warm conditions midweek, with downtown highs reaching the low-to-mid 90s on September 9 before the sea breeze and marine layer began reasserting themselves. National Weather Service and private model guidance now show the daily minimum on September 11 falling into the upper 50s to low 60s as onshore flow strengthens and clearer skies allow greater nocturnal radiational cooling. This places the most probable outcomes near the 58–61 °F range, consistent with climatological September lows around 56 °F. The near-even split between the 51 °F-or-below (50 %) and 70 °F-or-higher (49 %) buckets reflects remaining model spread on the exact strength and timing of the marine push versus any lingering warm advection. Key variables traders are watching include the depth and persistence of the marine stratus layer, wind speeds that modulate mixing, and any adjustments in National Weather Service or NOAA model runs over the next 48 hours. Resolution hinges on the official daily minimum recorded at the downtown San Francisco station.

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 11 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 cooling from returning marine influence after a midweek heat wave is the main driver of trader positioning for San Francisco’s September 11 low temperature.** A strong high-pressure ridge brought unusually warm conditions midweek, with downtown highs reaching the low-to-mid 90s on September 9 before the sea breeze and marine layer began reasserting themselves.
