Forecast models from the National Weather Service and others indicate Miami overnight lows on August 8 will likely settle between 78–82 °F, aligning with the closely matched market probabilities for the 78–79 °F, 80–81 °F, and 82–83 °F bins. Primary drivers include persistent high dew points near 75 °F that limit radiational cooling, variable cloud cover from typical summer convection, and light easterly winds that moderate the urban heat island effect around Miami International Airport. Recent model runs show minor differences in thunderstorm timing and coverage, which can raise or lower the minimum by 2–3 °F depending on whether skies clear after midnight. Historical August climatology places the average low near 78–79 °F, but current steering patterns and moisture levels introduce the narrow uncertainty reflected in trader positioning ahead of final observations.
