Trader sentiment for San Francisco's highest temperature on March 28 hinges on the latest NOAA forecast predicting a high near 64°F amid persistent marine layer influence, yet 32% market-implied odds for 74°F or higher reflect outlier model runs from ECMWF and GFS showing potential ridge-building aloft that could suppress coastal fog and allow adiabatic warming. Differentiating factors include onshore flow strength—favoring 66-67°F (21.5% odds) under typical stratus decks—and burn-off timing; partial clearing boosts 68-69°F (23.5%), while full sunshine is rare in late March, historically capping March 28 highs below 70°F nine times in ten. Uncertainty peaks pre-dawn March 28 observations.

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.
