Official National Weather Service observations from San Francisco stations recorded a daily maximum of 66–67°F on September 19, 2026, aligning precisely with the market’s near-certain outcome. Persistent marine-layer stratus and onshore flow suppressed inland warming, holding coastal highs several degrees below the 1991–2020 normal of roughly 70–75°F and preventing the brief ridge-driven warming seen earlier in the month. With the date now past and preliminary climate summaries released, traders assigned essentially 100% probability to this bin because verified station data leave no realistic path to a different resolution. Minor upward revisions in final quality-controlled records remain possible but historically rare for this location and threshold.

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.
