Miami's June overnight lows typically range from 78–82°F under subtropical high pressure, with limited radiative cooling due to high humidity and Atlantic/Gulf warmth. Current National Weather Service guidance points to a June 20 minimum near 79–81°F amid partly cloudy skies and light southerly flow, though scattered showers could enhance cooling in some model runs. Trader consensus clusters around 74–77°F because ensemble variability allows for brief wind shifts or clearer periods that might shave a degree or two below the baseline, while warmer outcomes gain traction if afternoon heating lingers into the night. No significant frontal passages or tropical influences are expected to alter the pattern before resolution.
