**Forecast models and official guidance from the National Weather Service indicate an overnight low in the upper 50s to low 60s Fahrenheit for San Francisco on September 8, 2026, aligning with the market's leading 60-61°F bin.** Persistent marine layer influence from the Pacific, combined with light winds and typical September coastal cooling, has kept recent daily lows near 56-61°F, consistent with climatological averages around 56°F but tempered by current warmer daytime conditions. Hourly observations early on the 8th show temperatures holding in the low 60s before dawn, with no strong offshore flow or clear-sky radiative cooling expected to push readings significantly lower. Updated model runs and the final official reading from downtown or airport stations will determine resolution, as minor forecast shifts in cloud cover or wind could adjust the exact minimum within the favored range.

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 8 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.**Forecast models and official guidance from the National Weather Service indicate an overnight low in the upper 50s to low 60s Fahrenheit for San Francisco on September 8, 2026, aligning with the market's leading 60-61°F bin.** Persistent marine layer influence from the Pacific, combined with light winds and typical September coastal cooling, has kept recent daily lows near 56-61°F, consistent with climatological averages around 56°F but tempered by current warmer daytime conditions.
