Trader consensus on Polymarket tilts toward 66-67°F (33.5%) as the highest temperature in San Francisco on April 19, closely trailed by 64-65°F (25.0%), reflecting National Weather Service guidance and GFS/ECMWF model ensembles projecting peaks in the mid-60s amid a developing upper-level ridge. Key differentiating factors include the persistence of the marine layer—a low stratus cloud deck driven by cool onshore flow—which could cap daytime heating at 64-65°F if it lingers past midday, or allow 66-67°F if it burns off earlier under increasing solar insolation. Historical April 19 highs average around 65°F, with ENSO-neutral conditions favoring typical cool spring patterns. Watch for NWS San Francisco Bay Area forecast updates and 00Z model runs overnight, as minor shifts in ridge strength or wind patterns could sway outcomes before resolution.

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 19 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 tilts toward 66-67°F (33.5%) as the highest temperature in San Francisco on April 19, closely trailed by 64-65°F (25.0%), reflecting National Weather Service guidance and GFS/ECMWF model ensembles projecting peaks in the mid-60s amid a developing upper-level ridge.
