Current National Weather Service and private model guidance points to an overnight low near 57–58°F for San Francisco on September 15, driven by moderate onshore flow and a modest marine layer that limits radiational cooling. Trader odds remain closely split between the 68°F-or-higher bucket and sub-50°F outcomes because small shifts in cloud cover, wind speed, or fog timing can alter the minimum by several degrees. Historical September lows average 56°F, with clear, calm nights occasionally dropping into the low 50s while stronger marine influence keeps readings higher. Updated model runs and local observations through September 14 will provide the key data releases that refine these probabilities before resolution.

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.
