Official National Weather Service observations at San Francisco International Airport recorded a daily maximum of 78–79°F on June 10, locking in the market’s 100% consensus on that bin. This outcome aligned with an incoming warm air mass and reduced marine layer influence that allowed inland heating to push coastal readings several degrees above June normals of 67–71°F. Model consensus from the prior 48 hours had converged on highs in the upper 70s, with minimal spread across guidance, limiting upside or downside revisions. Resolution hinges solely on the verified SFO climatological report; any post-event data correction or station-specific anomaly remains the only realistic path to reallocation, though such adjustments are rare once preliminary values are confirmed.
