Forecast models from the National Weather Service and private sources project overnight lows of 80–82°F in Miami on August 26 amid high humidity, persistent cloud cover, and a 70% chance of showers and thunderstorms driven by typical late-summer Atlantic moisture. These conditions limit radiational cooling compared to drier nights, keeping minimum temperatures above the long-term August average low near 78°F. Trader emphasis on the 80–81°F and 78–79°F bins reflects uncertainty in exact timing of any clearing or rainfall, with southeast winds of 5–10 mph offering little relief. Upcoming model runs and evening observations will refine whether localized downpours push the minimum slightly lower or sustain the warmer range.
