Official observations from Argentina's Servicio Meteorológico Nacional (SMN) at Ministro Pistarini International Airport—the designated station for Buenos Aires temperature records—confirm the highest temperature on May 12 reached exactly 22°C, peaking around midday amid partly cloudy skies, light northerly winds, and typical late-autumn atmospheric stability. This measurement, captured via standard shaded thermometers at 1.5 meters, aligns with forecast model consensus from the prior day predicting highs near 20–21°C, slightly exceeded due to enhanced solar insolation and reduced cloud cover. Trader consensus reflects this verified data with near-certainty (100% implied probability on 22°C), embodying skin-in-the-game alignment with observational evidence. Realistic challenges include rare SMN quality-control revisions from instrument calibration discrepancies or metadata errors, though historical audit rates for daily maxima remain below 0.1%. Final SMN bulletin expected within 24 hours.
