Trader consensus clusters around mid-70s highs for San Francisco on March 27, driven by the latest NOAA GFS and ECMWF ensemble forecasts showing a strengthening high-pressure ridge offshore, which limits cool marine layer intrusion and boosts daytime solar heating at SFO. This setup favors 72-73°F (22.5% implied odds) over slightly cooler 70-71°F (11%) due to lighter onshore winds—forecast below 10 mph—and warmer sea surface temperatures around 56°F enhancing low-level warmth. Differentiating warmer 74-75°F (19.5%) and 76-77°F (16.5%) hinges on ridge amplitude in final 12-24 hour runs; historical March variability at SFO (±5°F from 63°F average) underscores model spread, with new updates expected by evening.

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.
