**Traders have converged on 12°C as the lowest temperature in Buenos Aires on October 14, 2026, reflecting verified observational data from official Argentine meteorological stations.** This outcome aligns with real-time surface measurements showing the daily minimum reached exactly that threshold amid mild spring conditions, moderate cloud cover, and light southeasterly winds that limited overnight radiative cooling. Official records from the Servicio Meteorológico Nacional and stations such as Buenos Aires Observatory provide the authoritative ground truth used for market resolution, consistent with nearby model analyses reporting lows near 13°C before final verification. The near-100% implied probability underscores strong consensus on the recorded value. Only an unexpected post-event data revision or station-specific discrepancy could realistically shift the result, though such adjustments are rare once preliminary observations are confirmed.
