Official observations from the Servicio Meteorológico Nacional (SMN) stations, including Ezeiza Aerodrome—the primary reference for Buenos Aires—confirm the highest temperature on April 17 reached exactly 25°C amid partly cloudy skies and moderate southerly winds capping daytime heating. This outcome matched pre-event consensus from numerical weather prediction models like GFS and ECMWF, which projected highs near 24–25°C following recent frontal passage and typical autumn cooling trends in the region, where April averages hover around 22°C. Trader consensus at 100% implied probability reflects this verified data, with negligible risk of revision barring an extraordinary audit uncovering overlooked urban heat island effects or secondary station discrepancies. No further updates expected as the market nears resolution.
