Official meteorological observations from Brazil’s INMET and supporting global models confirm a daily maximum of exactly 22°C in São Paulo on May 31 under stable late-autumn conditions of limited moisture, weak pressure gradients, and moderate subsidence. This outcome aligns with climatological norms for the city at roughly 800 meters elevation, where late-May highs most often range 20–23°C. Trader consensus at 100% for 22°C reflects the completed observational record and absence of measurement uncertainty. Only a rare post-event data revision or station-specific discrepancy could alter resolution, though such adjustments remain statistically improbable given established verification protocols.
