Official observations from Los Angeles International Airport, the primary station for such markets, recorded a maximum of 79°F on September 14, 2026, aligning precisely with the market's 78-79°F outcome. National Weather Service preliminary climatological data confirmed this value under typical late-summer marine layer influence, with afternoon temperatures peaking near that level amid light southwest winds and minimal cloud interference. Historical averages for the date hover around 76°F, making the reading consistent with recent seasonal norms rather than an outlier. A material revision to the official report or station-specific anomaly could theoretically alter resolution, though such corrections remain rare once preliminary data stabilizes.
