Recent forecasts from the National Weather Service and major models converge on a San Francisco high near 67°F for August 14, 2026, with minor spreads explaining the tight 66-67°F and 68-69°F market bins. Persistent onshore flow and a moderate marine layer—common in late summer along the central California coast—limit daytime heating by advecting cooler Pacific air and promoting low stratus or fog that delays warming until afternoon. Slight model differences in the strength and timing of this layer, plus variations in wind speed and cloud cover, create the narrow gap between those leading outcomes. Historical August averages near 67°F provide climatological context, while traders weigh the latest model runs and observational trends ahead of final NWS verification at official stations.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the San Francisco International Airport Station in degrees Fahrenheit on 14 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the San Francisco International Airport Station, available here: https://www.wunderground.com/history/daily/us/ca/san-francisco/KSFO.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
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.
