**Forecasts from the National Weather Service and other models project a low temperature for Miami on August 23, 2026, in the upper 70s to low 80s°F, consistent with typical late-summer subtropical conditions.** Official NWS guidance shows a projected overnight low near 79°F for Miami under partly cloudy skies with a chance of evening showers and thunderstorms, while point forecasts and ensemble models indicate minimal overnight cooling due to high dew points (around 76–78°F) and light southerly winds. This setup limits radiative cooling, keeping the daily minimum elevated compared to drier or clearer nights. Trader sentiment, with the strongest implied probabilities on 78–81°F bins, aligns closely with this consensus and historical August climatology (average lows near 76–80°F at Miami International Airport). Recent model runs show little divergence, with no incoming fronts or significant moisture shifts expected to alter the outcome before resolution. Thunderstorm activity could slightly suppress or enhance the low depending on timing and coverage, but current guidance supports the narrow range dominating market odds.
