Official observations from Ministro Pistarini International Airport (Ezeiza), the market's resolution source, confirm Buenos Aires' highest temperature on May 5 reached exactly 24°C, aligning with trader consensus at 100% implied probability and driving the dominant positioning. This matches pre-event forecasts from Argentina's Servicio Meteorológico Nacional (SMN) projecting a maximum around 24°C under partly cloudy skies, light winds, and a stable high-pressure system suppressing further warming despite May's typical autumn highs of 18–20°C. Model ensembles like GFS and ECMWF showed consensus for mild conditions without significant heat advection. Realistic challenges would require a rare data revision from official METAR reports or sensor recalibration, though such post hoc adjustments are infrequent in verified aviation-grade measurements. Final SMN bulletin expected within 24 hours.
