Current forecast guidance for Miami points to a minimum temperature in the upper 70s to low 80s on August 17, driven by a persistent warm, moist subtropical air mass with high dew points limiting overnight radiative cooling. Light southeast winds and mostly clear to partly cloudy skies under a strong Bermuda high are expected to produce only modest diurnal ranges, consistent with climatological August lows averaging near 79–80°F. Minor variations in cloud cover or convective activity could nudge the actual low across the closely matched 78–81°F bins that dominate trader positioning. Updated National Weather Service model runs and evening observations will refine these thresholds ahead of resolution.
