Trader consensus at 20°C reflects verified post-event observations from meteorological networks, including Open-Meteo and NASA POWER data, which recorded a daily maximum of 20.3°C in Buenos Aires on October 14 amid typical spring variability. Regional conditions featured moderate drizzle, southeasterly winds around 12 km/h, and a temperature range of roughly 13–20°C, consistent with historical October baselines near 19°C. Official station reports and model analyses converged on this peak without notable discrepancies. Resolution hinges on precise measurement criteria such as station selection or rounding thresholds; minor revisions in final datasets or alternative monitoring sources could theoretically shift outcomes, though current evidence strongly supports the market-implied result.
