**Forecast consensus for Miami on August 29, 2026 centers on a daytime high in the upper 80s to low 90s °F, driven by typical late-summer subtropical conditions.** Official and model guidance from the National Weather Service, WeatherBug, and others project highs near 88–91 °F amid high humidity, east-southeast winds, and a 50–70 % chance of afternoon showers or thunderstorms. These convective clouds and rain frequently limit peak solar heating, keeping temperatures from climbing into the mid-90s or higher. Recent model runs and short-term updates show stable patterns with no major tropical systems or unusual steering features expected to alter the setup. Historical August averages for Miami hover around 89–90 °F, providing context for the current outlook. The market’s heavy weighting on the 90–91 °F bin (59 %) and nearby ranges reflects this narrow forecast envelope, with lower probabilities assigned to cooler outcomes if storms arrive earlier or to warmer ones only if skies clear more than anticipated. Updated NHC/NOAA briefings and afternoon model runs remain the key near-term data points that could shift implied probabilities before resolution.
