Forecast models from the National Weather Service indicate Miami's June 17 overnight low will likely settle in the upper 70s to low 80s, driven by persistent high humidity, limited radiative cooling under partly cloudy skies, and potential scattered showers that moderate temperature drops. Recent patterns show typical summer nocturnal lows near 78–80°F, with light southerly winds and high dew points suppressing further decline. The tight market split between 78–79°F and 80–81°F brackets reflects model spread on cloud cover and precipitation timing, while historical June climatology places average lows around 76–78°F. Updated evening model runs and local observations will refine the final reading before resolution.
