Trader consensus on Polymarket favors a high of 29°C in São Paulo on March 28 at 34% implied probability, aligning with the latest forecasts from Brazil's National Institute of Meteorology (INMET) and global models like ECMWF and GFS, which project daytime highs of 28–30°C amid partly cloudy skies and morning fog. Recent model runs over the past 48 hours show stable consensus, driven by persistent high-pressure patterns and minimal rainfall threats following last week's scattered showers that tempered earlier heat. Key variables include urban heat island effects amplifying city readings, southerly sea breezes potentially capping peaks at 28°C (11.5%), or unexpected insolation pushing toward 30–31°C (41% combined). New INMET updates and model refreshes expected today could refine these odds ahead of the evening resolution based on official airport station data.
