**Trader consensus has converged on 14°C as the lowest temperature recorded in São Paulo on August 24, 2026, reflecting official station observations placing the daily minimum near 13–14°C amid cooler-than-average winter conditions.** Data from São Paulo monitoring sites show a minimum of approximately 13.2°C with an average of 14.3°C and maximum of 16.3°C under mostly cloudy skies, consistent with seasonal norms for late August where overnight lows typically range 12–15°C. This outcome aligns with verified measurements from authoritative sources such as INMET-affiliated stations, where slight variations in microclimate or rounding protocols support the 14°C threshold over adjacent values. The market-implied odds exceeding 99% indicate high confidence in these post-event reports, with minimal uncertainty from model revisions or data adjustments expected at this stage. Scenarios that could challenge the resolution remain limited, primarily involving final quality-controlled updates from primary weather agencies that might shift the exact minimum by 1°C.
