Current forecasts from NOAA and AccuWeather place Miami's overnight low for June 27 in the mid-to-upper 70s°F, aligning with the market's tight clustering around the 74–83°F outcomes. High subtropical humidity and potential scattered cloud cover from Atlantic moisture reduce radiative cooling overnight, while light easterly trade winds and urban heat island effects limit further drops. Typical June climatology shows average lows near 76–78°F, and the absence of cold fronts or strong high pressure keeps extremes unlikely. Model spread in timing of any evening showers or wind shifts creates the balanced probabilities, with fresh runs expected to clarify the exact minimum before resolution.
