Forecast models from the National Weather Service and private sources indicate a high in the mid-60s°F for San Francisco on September 20, 2026, driven by a persistent marine layer and onshore westerly flow that limits daytime heating through extensive low cloud cover and high humidity near 85-95%. This setup aligns with typical September coastal climatology, where average highs reach about 71°F but often fall short under stratus influence. Current observations show overcast skies and temperatures climbing only slowly from overnight lows in the upper 50s, positioning 64-65°F as the market leader. Any breaks in cloud cover could allow modest warming toward 66-67°F, while sustained marine conditions favor the 62-63°F bin. Updated NWS guidance and afternoon observations will refine these probabilities ahead of market 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 20 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.Forecast models from the National Weather Service and private sources indicate a high in the mid-60s°F for San Francisco on September 20, 2026, driven by a persistent marine layer and onshore westerly flow that limits daytime heating through extensive low cloud cover and high humidity near 85-95%.
