Traders have settled overwhelmingly on 18°C as the highest temperature recorded in Buenos Aires on May 31, reflecting verified maximum readings from official Servicio Meteorológico Nacional stations that closed the observational period. Late-autumn climatology in the region features typical daily maxima of 15–20°C under stable high-pressure systems, and the absence of any significant warm advection or urban heat-island anomalies supports this precise outcome. Because the date has passed, forecast uncertainty no longer applies; only an improbable post-publication correction to the primary station data or an unrecognized station discrepancy could alter the recorded value.
