Official observations from Argentina's Servicio Meteorológico Nacional at Ministro Pistarini International Airport—the market's resolution authority—confirm Buenos Aires' highest temperature on May 3, 2026, peaked at 17°C around 4:00 p.m. local time under partly cloudy skies with light northerly winds and no precipitation. This outcome matched pre-event forecast consensus from SMN models predicting subdued autumn highs amid a cool air mass over the Pampas region, where May climatology averages 18–19°C but synoptic patterns like weak high-pressure ridging often cap peaks. Trader-implied odds at 100% for 17°C reflect this skin-in-the-game validation of precise, WMO-standard measurements. Realistic challenges are minimal, limited to rare data revisions from instrument audits, with negligible probability post-quality assurance.
