Official observations from Argentina's Servicio Meteorológico Nacional (SMN) at Ministro Pistarini International Airport—the market's resolution source—confirm Buenos Aires' highest temperature on April 20 reached exactly 19°C, driving trader consensus to 100% implied probability on this outcome. This reading aligns with autumn climatology for the region, where April averages hover around 20–22°C, but persistent cloud cover, high humidity above 90%, and an unstable low-pressure system with scattered showers capped daytime heating despite earlier forecasts near 22–23°C. Model consensus from SMN and international sources had anticipated mild conditions, yet real-time surface data reflects suppressed solar insolation. With data finalized, no realistic challenges remain barring rare measurement revisions.
