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 Apr '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.Trader consensus on Polymarket shows a razor-thin split favoring 62-63°F (39.5%) over 60-61°F (36.5%) for San Francisco's highest temperature today, reflecting inherent uncertainty in National Weather Service forecasts calling for a high near 65°F under mostly sunny skies with west winds of 7-11 mph. Cool Pacific sea surface temperatures around 55°F sustain a persistent marine layer of coastal stratus clouds, often delaying morning fog burn-off and capping diurnal heating in the low 60s at official stations like KSFO; however, stronger afternoon solar insolation amid lighter onshore flow could nudge peaks toward mid-60s. Recent days featured cooler-than-average highs (e.g., 55°F on April 9), but warming trends and model consensus point to this tight range. Hourly observations through evening will clarify resolution.
