Trader consensus on the 72-73°F bin edging the 70-71°F outcome reflects typical late-August uncertainty in San Francisco’s coastal microclimate. Persistent marine layer haze and moderate onshore westerlies at 10-20 mph from the Pacific are limiting daytime heating, consistent with National Weather Service guidance projecting highs in the upper 60s to low 70s. Subtle differences in marine layer burn-off timing, cloud cover, and wind strength can shift the daily maximum by 2-3°F; weaker onshore flow or earlier clearing favors the higher bin, while stronger winds or lingering fog anchor readings nearer 70°F. Historical August averages near 69°F and low precipitation probability reinforce the narrow spread between these leading outcomes.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the San Francisco International Airport Station in degrees Fahrenheit on 25 Aug '26.
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.
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.Trader consensus on the 72-73°F bin edging the 70-71°F outcome reflects typical late-August uncertainty in San Francisco’s coastal microclimate. Persistent marine layer haze and moderate onshore westerlies at 10-20 mph from the Pacific are limiting daytime heating, consistent with National Weather Service guidance projecting highs in the upper 60s to low 70s. Subtle differences in marine layer burn-off timing, cloud cover, and wind strength can shift the daily maximum by 2-3°F; weaker onshore flow or earlier clearing favors the higher bin, while stronger winds or lingering fog anchor readings nearer 70°F. Historical August averages near 69°F and low precipitation probability reinforce the narrow spread between these leading outcomes.
