National Weather Service forecasts and ensemble model runs currently indicate San Francisco will reach a daily high of 68°F or warmer on May 18, driven by a building high-pressure ridge that weakens the typical marine layer and allows warmer continental air to reach the coast. This setup aligns with late-May climatology, when highs average near 67°F but can exceed 70°F under reduced onshore flow. The overwhelming market-implied probability above 98 percent for 68°F or higher reflects this consensus from official guidance, though traders recognize that an unexpected strengthening of the marine layer or a shift in the steering pattern could limit afternoon warming and lower the peak temperature. Updated model runs and NHC-adjacent coastal observations will provide the next key data points before resolution.

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.
