Recent meteorological forecasts for Buenos Aires on August 21, 2026, center on a daily maximum near 12°C, reflecting the dominant influence of persistent cloud cover and cooler maritime air under a typical late-winter synoptic pattern in the city's humid subtropical climate. Official guidance and ensemble models show limited diurnal warming, with highs constrained by reduced insolation and light easterly or variable winds rather than strong cold advection. Historical August averages place daytime maxima around 15–17°C, but current conditions align more closely with the lower end of the climatological range, supporting the market's emphasis on 12°C and 13°C outcomes. Updated model runs and observational data through the preceding 24–48 hours have reinforced this consensus, with minimal upward revision expected absent rapid clearing.
