Trader sentiment clusters around 68-73°F for San Francisco's March 26 high temperature, driven by NOAA and ECMWF model consensus projecting a peak near 70°F under a strengthening high-pressure ridge off the California coast, which promotes adiabatic warming and delayed marine layer burn-off. This setup favors 70-71°F (25.5% implied odds) over slightly cooler 68-69°F (22.5%) due to expected clear skies by midday at SFO airport, the market's resolution source, with light onshore winds limiting coastal cooling. Warmer 72-73°F (22.5%) hinges on fuller stratus dissipation, per latest 12z GFS runs showing 1-2°F upside potential; historical March averages of 62°F underscore the ridge's outsized influence amid low precipitation risk.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the San Francisco International Airport Station once information is finalized, 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 to "Yes" until all data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
