Official observations from the Ministro Pistarini International Airport (Ezeiza, SAEZ)—the market's resolution authority—confirm the highest temperature on April 19, 2026, peaked at 26°C during mid-afternoon hours, per Servicio Meteorológico Nacional (SMN) bulletins and archived METAR reports. This outcome aligns with pre-event consensus from GFS and ECMWF forecast models, which projected mid-20s highs amid a stable high-pressure ridge, partly cloudy skies, light southerly winds, and above-average autumn warmth influenced by lingering La Niña transition effects. Trader sentiment at 100% implied probability reflects this robust observational evidence, with negligible risk of revision barring rare sensor anomalies or data audits uncovering higher peaks elsewhere, though airport readings govern resolution.
