Recent National Weather Service guidance points to Miami highs near 89–91 °F on August 8, driven by typical mid-summer subtropical ridging, moderate easterly flow, and afternoon sea-breeze convergence that can trigger convection. These factors limit peak solar heating when thunderstorms develop before maximum temperatures are reached, while clearer periods allow readings to approach or exceed the 91 °F August normal. Model spread centers on the precise timing and coverage of showers, which explains the near-even market split between the 90–91 °F and 92–93 °F bins. Updated short-range runs and local soundings will refine whether boundary-layer moisture or subsidence dominates the final maximum.
