Climatempo's latest forecast pegs São Paulo's high temperature at Guarulhos International Airport on April 4 at 29°C, with morning sun giving way to afternoon showers amid an 88% precipitation chance and 12 mm expected rain, aligning with trader consensus favoring 29°C (32.5% implied probability) over 28°C (26.5%) and 30°C (20.5%). This positioning reflects INMET's recent orange alert for intense Southeast Brazil rains through Saturday, introducing cloud cover and instability from a moist northwest flow that caps peak warming despite above-average autumn conditions (historical April highs average 25-26°C). Model ensembles like GFS and ECMWF show tight spread around 28-30°C, with differentiation hinging on shower onset timing—earlier clouds favor 28°C, delayed ones 30°C—prior to final observations resolving the market.
