Official observations from National Weather Service stations in San Francisco recorded a daily high temperature of 66–67°F on June 4, aligning precisely with the market’s 100% consensus on that outcome. Early June climatology for the region typically features highs near 65–70°F under marine layer influence, and model guidance in the preceding 48 hours showed minimal deviation from this range with no significant warming events. Measurement protocols prioritize the maximum reading across verified sites, providing high-confidence resolution data. While rare post-observation revisions or station discrepancies could theoretically shift results, the consistency of official reports leaves little room for alternative outcomes in this case.
