Latest short-range forecasts from meteorological services project São Paulo's highest temperature on April 6 at around 28°C (83°F), with highs of 83–86°F across models like those powering Time and Date and Weather Underground, reflecting trader consensus in the tightly clustered 27–29°C outcomes. This positioning stems from a persistent subtropical high-pressure ridge promoting morning sunshine and peak heating, tempered by potential afternoon thunderstorms that could cap maxima via increased cloud cover and reduced solar insolation. Recent days featured similar 29°C highs amid light winds and moderate humidity, slightly above April's climatological average of 26°C influenced by sea breezes and urban heat effects. Inherent forecast uncertainty arises from thunderstorm timing and model divergences; watch daily INMET updates and GFS/ECMWF runs for shifts ahead of resolution.
