Recent National Weather Service and ensemble forecasts for San Francisco on September 16 indicate an overnight low in the upper 50s to low 60s, driven by persistent onshore flow, a moderate marine layer, and limited radiational cooling under partly to mostly cloudy skies. These conditions align with historical September averages near 56°F while reflecting slightly above-normal warmth from recent days. Trader sentiment clusters around 58–61°F buckets because small differences in wind speed, cloud timing, and urban heat-island effects can shift the exact minimum by a few degrees across official stations. The elevated probability on 68°F or higher captures residual uncertainty if stronger mixing or delayed cooling occurs, though current model consensus favors the mid-to-upper 50s range. Updated NWS briefings and hourly observations will refine resolution criteria before market close.

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.
