Recent forecasts from sources including timeanddate and Ventusky indicate a maximum of roughly 11–12 °C for Buenos Aires on August 21 under mostly sunny skies, cooler than the long-term August average high near 16 °C. This stems from wintertime radiative cooling combined with a transient cold-air advection pattern that limits daytime warming despite clear conditions. Model consensus supports a narrow range centered on 12 °C, with modest uncertainty from exact boundary-layer mixing and local urban effects. Traders have priced 12 °C (54.5 %) and 13 °C (37.5 %) as the clear leaders, reflecting the tight clustering of official guidance and the low likelihood of significant deviation before resolution.
