Latest forecasts from Climatempo and INMET indicate a maximum temperature of 29°C at São Paulo-Guarulhos International Airport on April 4, reflecting trader consensus with 29°C at 33.5% implied probability, narrowly ahead of 28°C (25.5%) and 30°C (20.5%). A high-pressure ridge delivers dry southeasterly winds and low morning humidity (around 50-60%), enabling rapid solar heating above the April climatological average of 25-27°C, but afternoon convective showers (80-90% chance per models) introduce uncertainty—earlier onset favors 28°C by capping peaks, while delays could push to 30°C via prolonged insolation and weak sea breeze. GFS and ECMWF ensembles show this tight spread, with INMET hourly updates through midday pivotal for resolution.
