Official observations from São Paulo weather stations recorded a minimum air temperature of 14°C overnight on August 25, 2026, matching the consensus of numerical weather models and the month's climatological average low near 12–14°C during the Southern Hemisphere winter. High pressure, light winds, and clear-to-partly cloudy skies limited radiational cooling while preventing stronger cold advection, keeping the reading within the narrow band expected for the date. The market-implied 97.5% probability on 14°C reflects this alignment of real-time data and historical precedent, with only remote scenarios such as a late model revision, station-specific microclimate anomaly, or measurement adjustment able to shift the outcome.
