Official observations from Argentina's Servicio Meteorológico Nacional (SMN) at the Aeroparque station confirm Buenos Aires' highest temperature on May 9 reached exactly 13°C, anchoring trader consensus at a 100% implied probability for this outcome as the market nears resolution. This result matches SMN's pre-event forecast of 7–13°C maxima under overcast skies and a cool autumn air mass from polar outflows, corroborated by global model ensembles like ECMWF and GFS projecting subdued highs below the month's 18°C climatological average. Recent cooling trends over the prior week, including May 8's low-teens readings, reinforced this positioning. Scenarios challenging this near-certainty—such as a rare data audit or station-specific measurement dispute—are improbable given SMN's rigorous verification protocols, with final validation expected imminently.
