Ensemble forecasts from global models like GFS and ECMWF indicate a tight clustering of maximum temperatures around 27–28°C for São Paulo on April 2, driving the near-tie in trader odds at 29.5% each for those outcomes, amid typical early autumn conditions with highs averaging 26°C historically. Recent late-March stability under high-pressure systems has kept Southeast Brazil warmer than seasonal norms, but fading influences introduce uncertainty in cloud cover and sea breeze penetration, which could cap peaks at 26°C (18% implied probability) or push toward 28°C via enhanced solar heating. INMET guidance highlights low precipitation risk, though daily model updates may shift consensus; resolution hinges on official airport station readings.
