Forecast models from the National Weather Service and other agencies point to a peak temperature in the upper 80s for Miami on August 5, driven by typical subtropical summer conditions featuring a strong Bermuda High, light winds, and high boundary-layer moisture that favors scattered afternoon thunderstorms. These convective cells often develop by early afternoon, limiting solar heating and capping the daily maximum near the long-term early-August normal of 89–91°F at Miami International Airport. Recent model runs show minimal deviation from climatology, with no incoming tropical moisture surge or clear-sky high-pressure ridge to push readings into the low 90s or above. Trader consensus, reflected in the 49.5% implied probability for 88–89°F, aligns closely with this guidance, while the secondary weighting on 90–91°F accounts for residual uncertainty in storm timing and coverage.
