Persistent marine layer stratus and onshore flow from the cool California Current keep overnight lows anchored near seasonal normals of 56°F at SFO, with forecasts from NWS and local models showing a range of 55–57°F depending on exact clearing timing and boundary-layer mixing. A recent drier air mass has thinned the layer depth to around 1,400–1,600 feet, allowing partial radiative cooling under partly cloudy skies, while variable west-southwest winds of 10–15 mph limit further drops below 54°F. Trader consensus clusters on 54–57°F bins because small differences in inversion strength or stratus redevelopment overnight can shift the minimum by 2–3°F, consistent with historical August variability where coastal upwelling and pressure gradients dominate over synoptic changes.

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.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
