Current National Weather Service and ensemble model guidance for Miami on August 15, 2026, centers on a daytime high in the low 90s under typical subtropical summer conditions with easterly flow, high humidity, and sea-breeze influences that often limit afternoon peaks. This supports the market’s heavy weighting toward 92–93 °F while allowing a meaningful probability for 94–95 °F if convection remains suppressed. Afternoon thunderstorm development, common in the region during August, introduces the main source of uncertainty by potentially capping temperatures earlier than expected. Historical climatology for mid-August at Miami International Airport shows average highs near 90 °F with occasional excursions into the mid-90s, aligning with the current trader consensus reflected in the implied probabilities.
