Trader consensus on Polymarket overwhelmingly favors 76-77°F (98.8% implied probability) for Miami's lowest temperature on May 13, driven by Automated Surface Observing System (ASOS) data from Miami International Airport (KMIA), which recorded a minimum of 77°F around 6:53 a.m. amid partly sunny skies, light 3 mph winds, and 94% humidity—conditions ideal for minimal nocturnal cooling under a persistent upper-level ridge promoting above-normal temperatures. This aligns with May climatology, where the normal low is 73°F, but recent sunny days and weak sea breeze suppressed radiational cooling. Revisions in final National Weather Service (NWS) climate summaries are possible but rare without sensor anomalies; a drop to 74-75°F would require undocumented data adjustments from preliminary METAR reports. Watch for NWS Miami's daily CLI product confirming the observation.
