Recent National Weather Service and model guidance points to a cooling trend for San Francisco overnight into September 11, 2026, driven by strengthening onshore flow and marine layer development following a heat wave influenced by Tropical Storm Marie remnants. Forecast lows cluster in the upper 50s to low 60s°F, consistent with seasonal norms around 56°F but tempered by persistent west-southwest winds of 10–20 mph that limit radiational cooling. This supports the market's leading implied probabilities for 58–63°F ranges, while the 21% on 51°F or below reflects residual uncertainty if the marine push strengthens beyond current consensus. Updated NHC and local model runs through the evening of September 10 will refine overnight minimums ahead of 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.
