Recent forecast models from agencies like the Met Office and local observations point to a cool southerly airflow and extensive cloud cover suppressing daytime warming in Buenos Aires ahead of October 10. Persistent onshore winds advect milder maritime air while limiting solar insolation, with showers further moderating maximum temperatures. This setup favors market-implied highs clustered at 16–17°C, consistent with current ensemble guidance showing limited diurnal rise under overcast skies. Historical October averages near 19–20°C highlight the anomalously cool pattern, though small shifts in steering winds or cloud breaks could allow brief warming toward 18°C. Updated model runs over the next 48 hours will clarify resolution thresholds.
