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 15 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. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.The market's overwhelming consensus on a 64–65°F high for San Francisco on May 15 reflects National Weather Service observations at key stations, including San Francisco International Airport, confirming a peak temperature locked in that narrow band. Persistent marine-layer stratus and moderate onshore flow from the Pacific kept daytime warming suppressed, consistent with the city’s spring climatology where highs average near 64°F under typical coastal conditions. Global Forecast System and European Centre for Medium-Range Weather Forecasts runs showed strong agreement on this outcome through the preceding 48 hours, with no sign of the clear skies or offshore winds needed to push readings to 66°F or higher. A realistic challenge would require an abrupt shift in the sea-breeze regime or a rare warm-air advection event, neither of which appeared in final verified data.
