National Weather Service forecasts for Miami on May 3 project a high temperature near 88°F under a persistent ridge of high pressure, driving trader consensus to price "73°F or below" at just a 2.5% implied probability. This outcome faces significant climatological barriers, as May daily highs average 84°F with readings below 79°F occurring on fewer than 5% of historical days, bolstered by warm sea surface temperatures in the 80s°F from the Gulf Stream and negligible cold air intrusion risk this time of year. No recent model runs from NOAA ensembles indicate cooling trends, with recent days already logging highs above 85°F amid moderate heat risk alerts. Traders await the next NWS forecast update tomorrow for any shifts in boundary layer conditions or sea breeze influences.
