Current forecast models from agencies like the Met Office and timeanddate.com indicate a daytime high near 28°C for São Paulo on August 8, consistent with the market’s leading 28°C outcome at 36.5% implied probability. Southern Hemisphere winter conditions, including typical August dryness and moderate northwesterly flow, support temperatures 3–4°C above the monthly average of 23–25°C without triggering stronger warming. Recent model runs show limited variability, with possible peaks to 29–30°C if cloud cover remains minimal, aligning with the combined 43% probability on those bins. No significant cold front or heat anomaly has emerged in the past 48 hours to shift consensus away from this narrow range, though final resolution hinges on official INMET observations.
