Recent forecasts for São Paulo indicate the highest temperature on August 31 will likely fall between 31–34 °C amid a warm, dry air mass driving northerly flow, though model runs diverge on the exact timing of an approaching cold front that should bring cooler air and showers by September 1. Official guidance from sources such as the Met Office and Yr.no centers near 32 °C, while some ensembles project peaks near 34–37 °C if daytime heating persists under partly cloudy skies with limited moisture. Trader consensus reflected in the closely bunched probabilities around 29–32 °C captures this forecast uncertainty, as small shifts in front speed, wind direction, or cloud cover can alter maximum readings by several degrees on the Celsius scale. Updated model outputs and INMET briefings expected over the next 48 hours will likely refine the range.
