Official meteorological observations from São Paulo stations on August 4 confirmed a daily maximum of 26°C, aligning with the market's complete consensus at that outcome. This reflects typical subtropical winter conditions in the region, where August averages hover near 23–24°C under stable high-pressure systems and minimal frontal activity, as tracked by INMET data. The result sits comfortably within historical ranges without exceeding climatological norms for the period. While official records carry high reliability, rare post-event quality-control revisions or station-specific discrepancies could theoretically prompt reassessment, though such adjustments remain uncommon for near-real-time surface temperature readings.
