Confirmed hourly observations from Ministro Pistarini International Airport (Ezeiza) METAR reports establish 17°C as the highest temperature recorded in Buenos Aires on April 27, driving trader consensus to near-certainty on this outcome amid a polar cold outbreak affecting central Argentina. Strong southerly winds channeled Antarctic air masses northward, suppressing daytime highs well below the long-term April average of 22°C on the Saffir-Simpson climatological baseline for the region, aligning with Servicio Meteorológico Nacional (SMN) forecast consensus of 16–18°C. This unseasonably cool autumn day featured persistent cloud cover and gusty conditions, solidifying market-implied odds through skin-in-the-game verification. Realistic challenges are limited to rare post hoc data revisions from quality-controlled records, with SMN's final daily bulletin pending confirmation.
