Official measurements from São Paulo’s meteorological stations confirm a daily maximum of 22°C on May 17 under typical mid-autumn subsidence and light easterly winds that limited cloud cover and daytime heating. This observed value aligns precisely with the market’s 100% implied probability for the 22°C outcome, reflecting verified station data rather than model projections. Historical May averages hover near 22°C, providing climatological context for the result, while minor afternoon variations in insolation or wind shifts could have nudged readings toward 23°C. With the day concluded, trader consensus now rests on finalized observational records from Brazil’s national monitoring network, leaving negligible room for revision unless post-processing adjustments alter the official peak.
