The market's overwhelming consensus for a high of 68°F or higher on May 18 stems from National Weather Service model runs projecting reduced marine-layer influence and a strengthening high-pressure ridge over the Bay Area, which favors warmer offshore flow and clearer skies. These conditions align with climatological patterns where mid-May highs at San Francisco International Airport often reach the upper 60s when onshore winds weaken. Recent observational data show temperatures already trending above seasonal averages, with NOAA guidance maintaining this outlook through the weekend. A sudden return of dense fog or an unexpected strengthening of the marine layer remains the primary variable that could limit the peak below 68°F, though current ensemble forecasts assign low probability to that scenario.

This market will resolve to the temperature range that contains the highest temperature recorded at the San Francisco International Airport Station in degrees Fahrenheit on 18 May '26.
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.
