Forecast consensus from the National Weather Service and AccuWeather places Miami’s overnight low for July 26 in the upper 70s to low 80s, aligning with the closely matched market leaders at 78–79 °F and 80–81 °F. Typical mid-summer conditions—high humidity, light easterly flow, and scattered nocturnal thunderstorms—limit radiational cooling over the urban heat island and Atlantic-influenced coastline, keeping minimum temperatures near or slightly above the July climatological average of 78 °F. Minor model spread in boundary-layer moisture and thunderstorm timing creates the narrow probability gaps among the top bins, while warmer or cooler outliers remain less likely absent an atypical frontal passage or stronger sea-breeze interaction. Updated short-range guidance expected overnight will provide the next clear signal for traders.
