Forecast models from the National Weather Service and other agencies indicate a highest temperature in San Francisco on August 14 most likely in the upper 60s°F, aligning with the closely matched market-implied odds for 68-69°F and 66-67°F. Persistent onshore flow and the marine layer, reinforced by cooler Pacific waters, moderate afternoon highs along the coast while limiting inland heat advection. Typical mid-August climatology supports daily maxima near 68-70°F under partly cloudy to overcast conditions, with minimal day-to-day variability expected absent a strong offshore shift. Key resolution hinges on precise maximum readings at official stations, where even small changes in cloud cover or wind could distinguish between adjacent bins. Updated model runs and observations through the morning will provide the final data points for traders.

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.
