Forecast models for Buenos Aires on October 1 indicate a partly cloudy day with light southerly winds and possible morning showers under building high pressure, supporting a maximum temperature near 15–16 °C. Daytime heating will depend on cloud cover thickness and the timing of any clearing, while cool advection from the south limits warming potential compared to seasonal averages around 18–19 °C. Recent model runs show minor spread in peak values due to uncertainty in boundary-layer moisture and insolation, keeping market-implied odds closely split between 15 °C and 16 °C. Updated guidance from official sources ahead of the 24-hour period will clarify whether the high reaches 17 °C or stays at 14 °C.
