Official National Weather Service forecasts and model consensus point to a San Francisco high near the 70°F seasonal norm on September 6, driven by the typical early-fall marine layer that moderates coastal temperatures through onshore flow and afternoon cooling. Recent observations from September 1–5 showed daily highs of 68–71°F at downtown and airport stations, aligning with the 1991–2020 average of 70.2°F and keeping probabilities concentrated in the 70–71°F bin. Stronger warming would require a significant offshore wind shift or ridge buildup, neither of which current guidance supports 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 6 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.Official National Weather Service forecasts and model consensus point to a San Francisco high near the 70°F seasonal norm on September 6, driven by the typical early-fall marine layer that moderates coastal temperatures through onshore flow and afternoon cooling.
