Recent forecasts from multiple models indicate a cool, unsettled day for Buenos Aires on September 29, with a strong southerly flow and widespread cloud cover limiting daytime heating amid showers and thunderstorms. Official guidance points to a maximum near 18–20 °C, consistent with late-September climatology but tempered by the passage of a frontal system that has already produced alerts for heavy rain across the region. Trader consensus clusters tightly around 18–21 °C because small differences in the timing of any partial clearing or wind gusts can shift the daily peak by 1–2 °C. Updated model runs and official Servicio Meteorológico Nacional briefings over the next 48 hours will likely refine the precise maximum before resolution.
