Current forecasts from the National Weather Service and AccuWeather consensus place San Francisco’s August 21 high in the upper 60s, aligning with trader emphasis on the 68-69°F bin. Persistent marine-layer stratus, driven by cool California Current waters and a stable inversion reinforced by eastern Pacific low pressure and Four Corners high, continues to limit daytime warming along the coast. This setup mirrors typical mid-August climatology, where afternoon highs average near 67–70°F but frequently fall short when onshore flow strengthens. Recent model runs show no significant warming signals or marine-layer erosion through the 24-hour window, keeping probabilities anchored while acknowledging that any unexpected clearing or wind shift could push readings into the low 70s.

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 21 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.
