Recent forecasts from meteorological agencies point to a daily maximum in São Paulo around 27–29 °C on August 6, aligning with the market’s near-even split between 28 °C and 29 °C. In the Southern Hemisphere winter, regional high pressure and modest subsidence warming are supporting daytime peaks several degrees above the 23–25 °C August climatological average. Key variables separating the top outcomes include the timing and extent of any passing cloud cover or light showers, urban heat-island amplification in the city center versus official airport observations, and slight differences among numerical weather prediction runs. With resolution hinging on the single highest verified reading from Brazil’s national network, traders are closely tracking the latest model consensus and real-time station data through the afternoon heating period.
