Trader consensus on Polymarket heavily favors 30°C (37%) as Sao Paulo's highest temperature on March 24, driven by the latest INMET and ECMWF model runs projecting a daytime peak near 30°C amid moderating southerly winds following a recent heatwave. These odds reflect a cooling trend after early March highs exceeded 32°C, with urban heat island effects tempered by Atlantic sea breezes and post-El Niño stabilization. Historical March maxima average 28-29°C, but current ensemble forecasts show low dispersion around 29-31°C, sidelining extremes like 35°C+ (3.1%) or sub-25°C (0.8%); watch tomorrow's 12Z GFS update for potential shifts.
