NO. The market is fundamentally mispricing the climatological reality for Miami. A lowest temperature of 80-81°F on April 28th is an extreme, near-impossible scenario, wildly deviating from established norms. KMIA's 30-year average low for April 28th is 73.5°F, with 95th percentile minimums typically not exceeding 76-77°F. For the *lowest* temperature to register 80°F+, we would require an unprecedented confluence of persistent, robust nocturnal longwave radiation trapping, an exceptionally deep, stagnant tropical airmass maintaining dew points consistently above 78°F, and a complete absence of any diurnal cooling in the boundary layer due to an anomalously strong, sustained subsidence inversion. Neither the GEFS nor the ECMWF EPS extended ensemble prognostics for late April show any signal for the necessary synoptic ridging or advective patterns that could support such extreme minimum temperatures. Current model runs project KMIA lows firmly in the 70-76°F range. This isn't a high temperature bet; it's a lowest temperature bet. 99% NO — invalid if a Category 5 hurricane makes landfall directly over Miami between midnight and 3 AM on April 28th, generating anomalous latent heat release and extreme heat advection in the lower troposphere.
