**National Weather Service forecasts and supporting model runs position a high near 66°F as the most probable outcome for San Francisco on September 21, aligning with the market’s leading 66-67°F bin at 43% implied probability.** Persistent marine layer influence and onshore southwest flow are limiting daytime warming, consistent with observed highs of 63–64°F the prior day at key stations like SFO. Current guidance shows mostly cloudy skies transitioning to partly cloudy, with temperatures peaking in the mid-60s rather than approaching the 70.6°F late-September climatological average. Lower-probability bins above 68°F would require unexpected clearing and reduced marine influence, while cooler outcomes remain possible if cloud cover lingers. Updated NWS briefings and afternoon observations will provide the final data for 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 21 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.**National Weather Service forecasts and supporting model runs position a high near 66°F as the most probable outcome for San Francisco on September 21, aligning with the market’s leading 66-67°F bin at 43% implied probability.** Persistent marine layer influence and onshore southwest flow are limiting daytime warming, consistent with observed highs of 63–64°F the prior day at key stations like SFO.
