Official observations from Brazil's National Institute of Meteorology (INMET) and supplementary airport weather stations confirm Sao Paulo's highest temperature on March 25 reached exactly 30°C, with daytime highs stabilizing around that mark amid partly cloudy skies and moderate humidity levels typical for late austral summer. Preceding 48-hour forecasts from global models like ECMWF and GFS converged on this outcome, projecting limited solar heating due to cloud cover and weak sea breeze influences, aligning with historical March averages of 28–31°C at key monitoring sites. Trader consensus at 100% implied probability reflects this verified data, backed by real-money positions. Revisions could only arise from rare post hoc measurement corrections or disputes over the official station's reading, though INMET protocols make such shifts improbable.
