The dominant market consensus around a 52-53°F low in San Francisco on October 14 reflects verified observations from National Weather Service stations, where coastal marine-layer cooling and light onshore flow produced a minimum consistent with that narrow band. Recent model runs and post-event analyses from NOAA align closely with these readings, showing typical early-autumn conditions without significant warming or cold-air intrusions. Historical October climatology for the region supports this range as near-normal. While the strong implied probability indicates limited uncertainty, final official quality-controlled data releases or station-specific adjustments could still shift the recorded value into adjacent bins.
