Forecast models from the National Weather Service and others indicate a high near 68–70 °F for San Francisco on September 22, aligning with the market’s leading 68–69 °F bin at 33.5 % implied probability. Persistent marine-layer stratus and moderate onshore flow from the Pacific are expected to limit daytime heating, consistent with September climatology where average highs reach about 70.6 °F. Recent cooler conditions (mid-60s) reflect stronger than normal onshore winds and cloud cover, while any reduction in marine influence or clearer skies could allow readings into the low 70s. Key variables include forecast cloud fraction, wind direction and speed, and the precise timing of marine-layer clearance, all of which remain subject to short-range model adjustments before resolution.

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.
