**Latest National Weather Service guidance points to a Friday high near 66°F in San Francisco as a strengthening marine layer and onshore westerly flow advect cooler Pacific air onshore.** This follows several warmer, sunnier days and reflects the typical late-August pattern shift, with the shallow marine layer capping daytime heating under mostly cloudy skies and light-to-moderate west winds. Model consensus shows limited warming potential, with only modest model spread tied to the exact timing of any high clouds or brief clearing. Historical averages near 70°F underscore how the current synoptic setup favors the lower end of recent climatology, keeping the 66–69°F bins most probable while small forecast adjustments in boundary-layer moisture or wind speed could nudge readings into adjacent 64–65°F or 70–71°F outcomes.

The resolution source for this market will be information from NOAA, specifically the highest 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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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.
