Official measurements from the Servicio Meteorológico Nacional (SMN) and stations at Aeroparque Jorge Newbery and Ezeiza International Airport confirm Buenos Aires reached a maximum temperature of exactly 21°C on May 7, 2026, anchoring trader consensus at 100% implied probability for this outcome. Persistent cloud cover, scattered showers, and an advancing cyclogenesis—intensifying low-pressure systems with southerly winds—severely limited solar insolation and daytime heating, consistent with SMN advisories for unstable conditions. This aligns with May climatological norms, where highs average 19°C amid autumnal cooling. Realistic challenges are negligible absent rare data revisions from preliminary to final SMN records, expected within days.
