Official meteorological observations from Buenos Aires stations on September 16, 2026, recorded a daily maximum of 14°C under clear to partly cloudy skies with light to moderate northeasterly winds and low precipitation. This aligns with seasonal norms for mid-spring in the region, where average highs hover near 17°C but cooler air advection can suppress readings. Trader consensus at 100% implied probability for exactly 14°C reflects verified station data from sources like the Servicio Meteorológico Nacional, with minimal model uncertainty post-event. Minor revisions to archived readings or discrepancies between airport and urban stations remain the only realistic factors that could shift resolution, though historical patterns indicate such adjustments are rare for this threshold.
