**Trader consensus centers on 90–91°F (64.5% implied probability) as the most likely daily high for Miami on August 7, 2026, followed by 88–89°F (19.5%) and 92–93°F (11.0%).** These odds align closely with National Weather Service guidance calling for a high near 89°F under partly sunny skies with a 40–50% chance of afternoon showers and thunderstorms. In South Florida’s typical August regime, abundant moisture, light easterly flow, and sea-breeze convergence promote scattered convection that frequently limits afternoon temperature peaks near or slightly below model guidance. Recent model runs and local observations show highs in the upper 80s to low 90s, consistent with the long-term August average of roughly 88–90°F at Miami International Airport. The just-ended 56-day streak of 90°F+ readings (snapped on August 6 with an 88°F high) provides climatological context that traders weigh against today’s forecast. Uncertainty remains modest because thunderstorm timing and intensity can still shift the realized maximum by a degree or two, keeping secondary bins (88–89°F and 92–93°F) in play while rendering extremes well below 10% probability. Updated NWS discussions and afternoon model guidance will be the next key inputs likely to influence any late adjustments in market-implied odds.
