Trader consensus has settled decisively on an 88-89°F high for Miami on May 20, driven by National Weather Service observations and short-range model output that placed peak readings squarely in this interval. South Florida’s subtropical regime in late May typically features afternoon highs near 87°F under a persistent Bermuda high, with light easterly flow and moderate moisture limiting extreme surface heating. Current data from Miami International Airport and surrounding ASOS stations show no evidence of localized warming from urban heat islands or delayed sea-breeze effects that would push readings into the low 90s. Only a sharp, unanticipated shift in post-processing or an undocumented station bias could alter the outcome, scenarios viewed as improbable given the tight agreement across official datasets.
