Recent National Weather Service and AccuWeather guidance for Miami points to overnight lows near 80–82 °F on August 14, with the minimum typically occurring just before dawn under mostly cloudy skies and light easterly flow. High boundary-layer moisture and limited nocturnal radiative cooling—common in the subtropical maritime environment—keep temperatures from falling much below the mid-70s even on clearer nights, while scattered showers or increased cloud cover can raise the floor by a degree or two. Model consensus clusters in the low 80s, yet small differences in timing of any convective activity or wind shifts create the tight market split between the 80–81 °F and 82–83 °F bins. Historical August minima average around 78 °F, but persistent warmth this season has supported the current trader weighting toward the upper end of the normal range.
