Latest National Weather Service forecasts for San Francisco on March 28 indicate a high temperature clustering around 66-71°F, driving trader consensus with 22% odds on 66-67°F as the slim leader amid tight competition. This reflects ensemble model means from GFS and ECMWF, projecting partial clearing of the persistent coastal marine layer after morning stratus, allowing modest diurnal heating under weak high-pressure ridging aloft. Differentiating factors include model spread on boundary-layer mixing and onshore flow strength: warmer GFS runs favor 70-71°F via enhanced subsidence, while cooler ECMWF ensembles emphasize stratus persistence capping peaks at 66-67°F. Historical March 28 highs average 62°F, underscoring the 5-10°F anomaly from current synoptic setup, with final resolution hinging on afternoon insolation observed at SFO.

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.
