Recent forecasts from the National Weather Service and AccuWeather place Miami’s August 15 high near 90–93 °F, aligning with the market’s heavy weighting toward the 92–93 °F bin. Typical mid-August steering patterns feature light easterly flow and daytime sea-breeze convergence that caps extreme heating while afternoon convection can shave a degree or two from peak readings. Model consensus shows no significant tropical moisture surge or upper-level ridge strengthening that would push readings into the mid-90s or higher, keeping the upper tail of the distribution slim. Historical normals list a 91 °F daily maximum, and the past several days have run 1–3 °F above that baseline under similar synoptic conditions, supporting the current implied probabilities. Updated NWS guidance and any late-day model runs will be the next key inputs traders monitor before resolution.
