INMET's latest forecast projects a maximum temperature of 28°C for São Paulo on May 2 under mostly cloudy skies, high humidity (55-95%), and minimums near 19°C, closely tracking trader consensus with 29°C at 36% implied probability, 30°C at 29%, and 28°C at 29%. Tight odds reflect inherent short-term forecast uncertainty, where variable afternoon cloud breaks could boost solar insolation for brief spikes to 29-30°C, while persistent overcast and moist air suppress peaks at 28°C—differentiated by model ensembles showing slight spread in boundary layer heating. Above May's climatological high of 23°C amid recent autumn warmth, resolution hinges on observations at Guarulhos Airport; watch INMET's May 1 update for refined guidance.
