Current forecasts from regional models point to a maximum temperature of 17–19°C in Buenos Aires on August 16, aligning with the market's leading outcomes at 18°C (49%) and 19°C (32.5%). Typical Southern Hemisphere winter conditions feature moderate north winds, persistent cloud cover, and limited solar heating that cap daytime peaks near the long-term August average of 15–18°C. Recent observations show stable mild air masses with no strong warm advection or clear-sky radiative warming to push values higher, while official guidance notes possible light precipitation that further suppresses maxima. Traders appear to weight these ensemble outputs heavily, with lower probabilities assigned to outliers beyond 20°C given the season's climatological constraints and short-term stability.
