Trader consensus on Polymarket tilts toward 29°C (39%) as Sao Paulo's highest temperature on March 24, driven by the latest ECMWF and GFS ensemble forecasts projecting a midday peak of 28-30°C under partly cloudy conditions with light northeasterly winds moderating urban heat buildup. Recent INMET updates and Climatempo models show minimal spread, with 30°C viable if sea breezes weaken, while 28°C reflects higher cloud cover scenarios from ICON runs. Historical March maxima average 28.5°C, but this week's warm anomaly—fueled by subsiding high pressure—nudges odds upward; key uncertainty lies in afternoon convection potentially capping the high, per NOAA satellite data.
