The market's 100% consensus on an 80-81°F low for Miami on August 20 reflects the official minimum temperature recorded at Miami International Airport, which aligned precisely with that narrow band amid elevated overnight readings. Persistent warmth from a strong subtropical ridge, combined with high dew points near 75°F and limited radiative cooling under partly cloudy conditions, kept the daily low well above the 1991-2020 climatological average of 77.7°F. Recent heat-wave conditions, including a 100°F record high two days earlier, further suppressed nocturnal temperature drops across South Florida. While official National Weather Service verification and station data underpin this outcome with high confidence, minor discrepancies in preliminary versus final reports or localized microclimate effects could theoretically have shifted the exact value, though none materialized here.
