Recent forecasts from meteorological agencies indicate a daytime high of 11–13°C for Buenos Aires on August 12, reflecting typical mid-winter Southern Hemisphere conditions with light easterly maritime flow from the Atlantic and persistent cloud cover that restricts solar heating. Model consensus highlights limited diurnal temperature rise under overcast skies and possible light rain, suppressing maxima below the month’s climatological 15–17°C average. These factors create tight uncertainty between 12°C and 13°C outcomes, as small variations in cloud timing or wind strength could shift the observed peak by 1°C. Traders weigh official guidance from agencies like the Servicio Meteorológico Nacional against historical analogs for cool, stable winter patterns in the region.
