**Forecast models from sources including the BBC and regional meteorological services indicate a highest temperature in Buenos Aires on August 10, 2026, most likely between 11–13°C.** This aligns with the market's heavy weighting toward 12°C (52.5% implied probability) and 13°C (35.5%), reflecting trader consensus on stable winter conditions. In the Southern Hemisphere winter, Buenos Aires experiences typical daily highs near the long-term August average of about 14–17°C, with recent observations showing values around 13–15°C on preceding days. Current guidance points to clear or mostly clear skies, light southerly winds, and no significant warm advection or frontal systems, keeping the daily maximum in the low-to-mid teens Celsius. Ensemble forecasts emphasize limited variability, with minimal risk of outliers above 14°C or below 11°C under the prevailing high-pressure influence. Recent cold anomalies noted in July (including rare snowfall in parts of Argentina) have moderated into early August, supporting near-normal or slightly cooler conditions without major shifts. Updated model runs and official briefings in the next 24 hours will refine exact values, but current data reinforce the concentration of probability around 12–13°C.
