Market consensus for a 20°C daily maximum in São Paulo on June 1 reflects official meteorological observations confirming that peak temperature under typical early-winter conditions. Regional monitoring data showed stable atmospheric patterns with no significant warming from subtropical highs or reduced cloud cover that could have pushed readings higher. June averages for the city center around 21–23°C, placing 20°C squarely within expected variability for the season. Traders priced in the outcome at essentially 100% once real-time station reports aligned precisely with this threshold, consistent with historical baselines from national weather services. Only an uncharacteristic late-day spike from localized urban heat effects or measurement revision would have altered the resolution criteria.
