National Weather Service forecasts indicate a high near 63°F for San Francisco downtown this afternoon under sunny skies, with observations at San Francisco International Airport (KSFO)—the likely resolution station—already peaking at 63°F by mid-afternoon amid partly cloudy conditions and gusty west winds of 17-29 mph. Trader consensus splits closely between 62-63°F (38.5%) and 60-61°F (36%) due to marine layer variability: persistent low-level stratus or stronger sea breeze could cap warming at 61°F, while complete burnoff allows 63°F peaks consistent with NOAA model ensembles clustering 59-63°F. April climatology averages 63-66°F highs, but boundary layer mixing and solar insolation timing introduce uncertainty; final ASOS data expected by evening will resolve the market.

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.
