**Trader sentiment for Miami’s August 5 overnight low centers on the 78–81 °F range (combined ~63 % implied probability), reflecting the narrow spread in official forecasts and climatological norms.** Persistent high humidity, abundant tropical moisture, and frequent cloud cover are limiting overnight radiative cooling, keeping minimum temperatures elevated relative to drier continental climates. National Weather Service guidance and model consensus currently point to a low near 80 °F, consistent with the recent run of 79–81 °F observations and the August climatological average of ~78 °F at Miami International Airport. Weak steering flow and possible scattered showers add minor variability but are not expected to produce significant cooling. The close contest between the 80–81 °F and 78–79 °F bins captures remaining uncertainty in the final model guidance and the precise timing of any cloud breaks or sea-breeze effects before dawn on the 5th.
