Latest forecasts from Brazil's Instituto Nacional de Meteorologia (INMET) and Climatempo project São Paulo's highest temperature today at 26–27°C under partly cloudy skies with low rain chances, aligning with trader sentiment favoring 27°C (44% implied probability), 28°C (26%), and 26°C (23%). This reflects consensus among GFS and ECMWF models showing moderate diurnal heating after a cold front earlier in the week dissipated, with light winds and humidity around 80–90% limiting extremes. April historical averages hover at 25°C highs amid autumn cooling trends, but current conditions support a mild rebound. Uncertainty stems from potential irregular showers capping peaks; hourly updates from São Paulo-Guarulhos International Airport observations will clarify resolution later today.
