Trader sentiment for San Francisco's March 25 high temperature splits tightly across mild ranges, with 70°F+ leading at 30% on optimistic GFS ensemble runs hinting at a building high-pressure ridge over California, potentially overriding coastal cooling. Official NOAA forecasts center around 66-67°F, aligning with 21% odds each for 64-65°F and 66-67°F, reflecting persistent marine layer influence from Pacific advection fog that caps diurnal heating. Differentiating factors include offshore winds boosting adiabatic warming for upper bins versus onshore flow and stratus decks favoring 62-63°F (18%), per historical late-March baselines averaging 62°F amid model divergence; watch evening ECMWF updates for resolution shifts.

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.
