Trader consensus on the 70-71°F bin reflects the official high temperature recorded on August 13, 2026, at the resolution station, which aligned precisely with that narrow range after a period of marine layer moderation. National Weather Service observations and nearby station data confirmed peak readings near 70°F amid typical August coastal patterns, where onshore flow and fog limited daytime warming below seasonal norms around 71-74°F. This outcome matches climatological baselines for San Francisco in mid-August, with minimal model deviation from prior forecasts. Only an anomalous heat spike from offshore flow or measurement revision at the exact station could have shifted resolution, though no such data emerged.

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 13 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.
