Current forecast models from sources including timeanddate and the Met Office indicate a high near 13°C for Buenos Aires on August 22 under sunny conditions with light southerly winds, aligning with the market's emphasis on 13–15°C outcomes. In Southern Hemisphere winter, radiative cooling overnight and modest daytime insolation typically produce highs of 12–16°C; recent August observations show averages around 15°C with normal variability of several degrees driven by high-pressure systems and limited moisture. Clear skies and stable steering patterns favor the current consensus range, while any shift in cloud cover or wind could alter the exact maximum recorded at official stations.
