Current meteorological models and observational data position a maximum of 22°C as the most probable outcome for São Paulo on May 17, reflecting typical late-autumn conditions with daytime highs averaging 22–23°C. Stable high-pressure systems and moderate humidity levels have limited convective activity, keeping temperatures from exceeding seasonal norms or dropping sharply overnight. Recent model consensus from global ensembles shows minimal day-to-day variability, with wind patterns favoring gradual warming rather than rapid shifts. Traders’ heavy weighting toward 22°C captures this steady baseline, while the modest probability for 23°C or higher accounts for any localized urban heat effects or slight forecast adjustments before resolution.
