Trader consensus on Polymarket overwhelmingly assigns 100% implied probability to 29°C as São Paulo's highest temperature on May 5, 2026, reflecting official observations from the São Paulo-Guarulhos International Airport (SBGR) meteorological station, where METAR reports confirmed this peak amid partly cloudy skies and light winds. Instituto Nacional de Meteorologia (INMET) data aligns, showing daytime highs reaching 29°C during a brief autumn warm spell driven by high-pressure subsidence and minimal cloud cover, exceeding typical May averages of 23–25°C. Model forecasts from INMET and Climatempo had anticipated 27–28°C, with actual readings slightly warmer due to enhanced solar heating. Scenarios challenging this include rare post-event data revisions from quality control or discrepancies between automatic and manual station records, though such adjustments are infrequent for resolved daily maxima. Final INMET bulletin expected within 48 hours.
