Official meteorological observations from São Paulo on August 15 confirmed a daily maximum of 22°C at primary stations, consistent with typical mid-winter conditions in the region where average highs range 23–25°C under stable high-pressure systems and minimal cloud cover. Trader consensus at 100% reflects verified data from agencies like INMET, with no model revisions or measurement discrepancies reported. Realistic challenges remain limited to rare post-hoc adjustments for station calibration or localized microclimate anomalies, though such revisions are infrequent once preliminary readings align across networks.
