**Persistent warm, humid conditions under northeast flow following a weak frontal passage have kept overnight lows in Miami in the upper 70s on October 13, 2026, driving the strong market consensus around 78-79°F.** Official observations at Miami International Airport recorded a minimum of 78°F early that morning, consistent with National Weather Service forecasts projecting lows near 77-80°F amid mostly clear skies and dew points in the low 70s. This outcome aligns with mid-October climatology, where average lows hover near 75°F, and the modest cooling from the front proved insufficient to push temperatures into the mid-70s or below. Recent model consensus and surface observations reinforced expectations of limited diurnal cooling under light winds and high moisture, resulting in the 85% implied probability for the 78-79°F bin while assigning negligible odds to cooler thresholds.
