Latest National Weather Service forecasts and NOAA model ensembles, including GFS and ECMWF runs, project persistent onshore flow and deep marine layer over San Francisco on April 1, capping highs at 60-61°F under partly cloudy skies—this drives the leading 37.5% implied probability from traders wagering real capital. Following a recent warm anomaly with 80s°F highs in mid-March due to high pressure ridging, a mid-level trough now ushers cooler air masses and enhanced coastal stratus, trimming peaks 3-5°F below early April climatological normals of around 63°F at SFO. Key uncertainties include stratus burn-off timing and low-level wind mixing, with resolution hinging on official observations; watch 00z/12z model updates Sunday for potential shifts ahead of the event.

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.
