**Latest numerical weather prediction models from sources including the ECMWF and GFS indicate a minimum temperature for Buenos Aires on October 13 most likely in the 12–14 °C range.** Persistent easterly to southeasterly flow, extensive low- to mid-level cloud cover, and light drizzle or showers are expected to limit nocturnal radiative cooling and hold overnight lows above typical early-spring values. Ensemble spreads remain modest, with few members dipping below 10 °C or exceeding 16 °C, reflecting stable steering patterns and the absence of a strong cold-air advection event. Historical October minima average near 11–12 °C, providing context for the current mild outlook. Traders appear divided between the possibility of a brief colder outlier versus warmer boundary-layer mixing, with fresh model runs and local observations the next key inputs likely to refine implied probabilities.
