Trader consensus on Polymarket heavily favors a Sao Paulo high of 31°C (29%) on March 28, driven by the latest ECMWF and GFS ensemble forecasts projecting peaks near 30-32°C under a dominant subtropical high-pressure ridge fostering clear skies and radiative heating. Recent model runs show slight divergence, with GFS trending hotter (32°C+) and ECMWF cooler (29-30°C), amplifying uncertainty reflected in the spread across 27-33°C outcomes. Key variables include urban heat island effects boosting city readings 2-3°C above rural stations, Atlantic sea breeze timing that could temper afternoons, and risk of isolated thunderstorms capping peaks below 29°C. Historical late-March averages hover at 28°C, but this year's warmer autumn pattern tilts odds upward.
