Trader consensus on Polymarket closely splits between 30°C (32%) and 29°C (30.5%) as Sao Paulo's highest temperature on March 28, driven by converging forecast models amid lingering summer warmth in Brazil's southeast. INMET's latest guidance projects a daytime max near 29-30°C under partly cloudy skies with moderate humidity around 70%, while ECMWF and GFS ensembles show minor divergence—ECMWF leaning 29°C due to potential afternoon sea breeze moderation, GFS edging toward 30°C with stronger solar heating. Urban heat island effects in Sao Paulo amplify peaks by 1-2°C above rural stations, but timing of convective showers remains uncertain, per recent 00Z model runs. Official hourly updates from INMET expected midday could sharpen resolution before evening close.
