Latest forecast models from sources including the National Meteorological Service of Argentina and international ensembles indicate a maximum of 12–13°C in Buenos Aires on August 8, driven by a transient high-pressure ridge suppressing warmer northerly flow and allowing cooler southerly advection under partly cloudy skies. Typical August climatology features daytime highs near 16–17°C, but recent model runs show a 2–4°C negative anomaly tied to a passing cold front and reduced solar insolation, narrowing the range between leading 13°C and 14°C outcomes. Resolution hinges on the official Servicio Meteorológico Nacional observation at the central station, with minimal precipitation expected to limit diurnal variability. Traders weigh ensemble spread in boundary-layer mixing and wind direction as the key uncertainties separating these closely matched probabilities.
