**Official observations confirm a minimum of 58°F at San Francisco International Airport on September 18, 2026, aligning with the market's dominant 58-59°F outcome at 91.5% implied probability.** This reading occurred at 6:18 AM under typical late-summer marine layer conditions, with high humidity near 93% and fog/haze reported, producing a low just 2°F above the 1991-2020 normal of 56°F. The daily high reached only 69°F amid moderate westerly winds, consistent with seasonal patterns where coastal upwelling and onshore flow suppress overnight temperatures. Trader consensus reflects the reliability of NWS data and the low likelihood of revisions or alternative station readings altering the result. Unlikely shifts could arise only from post-analysis corrections or if the market resolves on a non-airport station, though historical precedent favors the primary SFO report.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the San Francisco International Airport Station in degrees Fahrenheit on 18 Sep '26.
The resolution source for this market will be information from NOAA, specifically the lowest 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 observations confirm a minimum of 58°F at San Francisco International Airport on September 18, 2026, aligning with the market's dominant 58-59°F outcome at 91.5% implied probability.** This reading occurred at 6:18 AM under typical late-summer marine layer conditions, with high humidity near 93% and fog/haze reported, producing a low just 2°F above the 1991-2020 normal of 56°F.
