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 13 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 sentiment on San Francisco's highest temperature April 13 tilts narrowly toward 60-61°F and 62-63°F, reflecting National Weather Service guidance and GFS/ECMWF ensemble consensus projecting daytime highs in the low-to-mid 60s amid persistent marine layer stratus clouds. Recent observations through April 10 show onshore winds strengthening, fostering thicker low clouds that cap heating—evident in highs dipping from 67°F earlier in the week—while historical April 13 averages hover near 63°F. Differentiating factors include model spread on stratus burn-off timing: drier runs favor quicker clearing for 62-65°F, but moister scenarios with sustained southwest flow limit peaks to 60°F. New 00Z/12Z forecasts tomorrow could sharpen resolution as the event nears.
