**Current National Weather Service and model consensus points to a high temperature in the mid-to-upper 70s°F for San Francisco on September 7, driven by persistent onshore flow and marine-layer moderation from the Pacific that limits daytime heating despite a broader regional warming trend.** Official point forecasts list highs near 75–78°F under mostly sunny skies, with light northwest winds and minimal cloud cover expected to allow modest warming above the long-term September 7 average of roughly 70°F. Recent observations show the city running slightly above normal early in the month but without the strong offshore flow or subsidence needed for 80°F-plus readings. Traders have priced the 76–81°F bins highest because ensemble guidance shows little spread around this range, though minor shifts in wind direction or marine-layer depth could still adjust the final maximum by a degree or two before resolution.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the San Francisco International Airport Station in degrees Fahrenheit on 7 Sep '26.
The resolution source for this market will be information from NOAA, specifically the highest 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.**Current National Weather Service and model consensus points to a high temperature in the mid-to-upper 70s°F for San Francisco on September 7, driven by persistent onshore flow and marine-layer moderation from the Pacific that limits daytime heating despite a broader regional warming trend.** Official point forecasts list highs near 75–78°F under mostly sunny skies, with light northwest winds and minimal cloud cover expected to allow modest warming above the long-term September 7 average of roughly 70°F.
