Official observations from Argentina's Servicio Meteorológico Nacional (SMN) confirm the highest temperature in Buenos Aires reached exactly 23°C on April 15, 2026, primarily at Aeroparque Jorge Newbery station, driving trader consensus to 100% implied probability on this outcome. This measurement aligns with a cooling trend following April 14's near-25°C peak, as a passing frontal system ushered in southerly winds, extensive cloud cover, and scattered light rain that suppressed daytime heating despite lingering humidity. Forecasts from NOAA and SMN models had converged on 21–23°C ranges amid typical autumn variability, with historical April maxima averaging 22°C. Scenarios challenging this would require a rare post hoc data revision from sensor recalibration or dual-station discrepancies, though preliminary SMN reports render such shifts improbable.
