**Official National Weather Service forecasts for San Francisco on September 21, 2026, call for a daytime high near 66°F (19°C), with a slight morning chance of drizzle followed by gradual clearing to mostly sunny skies and southwest winds of 5–15 mph.** This aligns with the market's leading outcomes in the 64–69°F range, reflecting the strong marine influence typical of the Bay Area, where cool Pacific air and the marine layer moderate temperatures below inland norms. Recent observations show morning readings in the mid-50s to low 60s, consistent with model consensus and historical September patterns averaging around 70°F but often cooler coastally. Minor forecast uncertainty around cloud cover and exact peak timing supports the clustered probabilities, with traders weighting official guidance from NWS and local monitoring stations for 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.**Official National Weather Service forecasts for San Francisco on September 21, 2026, call for a daytime high near 66°F (19°C), with a slight morning chance of drizzle followed by gradual clearing to mostly sunny skies and southwest winds of 5–15 mph.** This aligns with the market's leading outcomes in the 64–69°F range, reflecting the strong marine influence typical of the Bay Area, where cool Pacific air and the marine layer moderate temperatures below inland norms.
