Official temperature observations from National Weather Service stations in the Los Angeles area recorded a daily maximum of 72–73°F on October 11, driving the market’s near-certain consensus on that bin. Clear, stable atmospheric conditions with minimal marine layer influence and light onshore flow kept afternoon highs in that narrow range, consistent with climatological norms for mid-October in the basin. With the observation period now closed and data verified, only rare post-event revisions—such as station calibration adjustments or quality-control corrections—could alter the recorded value, though such changes are uncommon for routine surface measurements.
