Trader consensus clusters on the 58–61°F range for San Francisco’s September 8 low, reflecting National Weather Service forecasts of 58°F and supporting model guidance near 59°F amid typical early-September marine-layer conditions. Persistent onshore flow and stratus development overnight moderate radiative cooling, while recent daily lows of 56–61°F establish a climatological baseline without strong high-pressure ridging to drive sharper drops. Key variables include marine-layer depth, wind speed, and any last-minute shifts in the 500-hPa pattern that could alter cloud cover before the 24-hour observation window closes. Updated NWS guidance and short-range model runs remain the primary near-term catalysts.

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 8 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.Trader consensus clusters on the 58–61°F range for San Francisco’s September 8 low, reflecting National Weather Service forecasts of 58°F and supporting model guidance near 59°F amid typical early-September marine-layer conditions.
