Recent National Weather Service and private model guidance points to overnight lows near 58–59°F for San Francisco on September 12, yet trader consensus remains nearly evenly split between a minimum of 49°F or below and 68°F or higher. This polarization reflects uncertainty in the strength and timing of the marine layer, onshore flow, and any late-day clearing that could allow radiational cooling or retain warmth. Historical September lows average 56°F with a record floor of 49°F, while recent September conditions have shown day-to-day swings of several degrees driven by wind shifts and cloud cover. Updated model runs and evening observations over the next 48 hours will likely determine whether the minimum settles in the typical upper-50s range or deviates toward either tail.

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.
