Official observations from the National Weather Service Miami station recorded a minimum temperature of 77°F on September 14, 2026, aligning closely with the long-term seasonal normal of 77°F and recent days' readings under persistent high humidity, light variable winds, and scattered light rain with no frontal passages or significant cooling. This stability in subtropical late-summer conditions, with highs near 90°F and minimal overnight radiative cooling, underpins the market's near-certain consensus around 78-79°F. A realistic challenge would require an unreported measurement discrepancy or station-specific anomaly, though verified climatological data from the 1991-2020 baseline and ongoing monitoring make such revisions improbable before final settlement.
