Trader consensus on Polymarket has locked in 29°C as the highest temperature at São Paulo-Guarulhos International Airport on May 2, 2026, with near-100% implied probability, driven by official midday observations peaking at 29°C amid partial cloud cover and low relative humidity dipping to 30%, aligning with INMET and CPTEC ensemble forecasts predicting a maximum in that range under a dominant mass of dry air suppressing clouds and precipitation. This outcome reflects real-time METAR reports from the airport station, the market's resolution source via Weather Underground historical data, confirming no higher readings through evening. While data finalization is typically firm, a rare post-audit revision by INMET—such as sensor recalibration—could challenge this, though historical precedents show such adjustments under 0.5°C and infrequent after 24 hours.
