Official observations from Brazil's Instituto Nacional de Meteorologia (INMET) and METAR reports at São Paulo-Guarulhos International Airport confirm a peak temperature of 30°C reached mid-afternoon on March 28, under predominantly clear skies and light winds from a stable high-pressure system. This aligns with forecast ensembles from global models like ECMWF and GFS, which projected maxima around 29-30°C amid low humidity and strong solar insolation, consistent with late-March climatology averaging 28°C but elevated by urban heat island effects. Trader consensus at 100% implied probability reflects this observational certainty as the day nears resolution, with final INMET daily summaries expected shortly; a rare late-afternoon convective clearing or data revision could theoretically push higher, though probabilities remain negligible given cooling trends post-sunset.
