Official observations from Argentina's Servicio Meteorológico Nacional (SMN) and METAR reports at Ministro Pistarini International Airport (Ezeiza, SAEZ) confirm the highest temperature on April 9 reached exactly 21°C, aligning with trader consensus at 100% implied probability for that outcome. This mild autumn reading reflects stable atmospheric conditions, including partly cloudy skies, moderate southerly winds, and post-frontal cooling after earlier instability, consistent with SMN pre-event forecasts of 20-22°C maxima. April climatology supports such levels, with historical Ezeiza highs averaging around 21°C. Realistic challenges are minimal—only a rare data audit revealing an overlooked peak could shift resolution, though standard verification protocols make this improbable. Traders await final SMN daily summary for closure.
