Current forecast models from multiple sources indicate overnight lows near 12–13°C in Buenos Aires on October 9 amid persistent cloud cover, light rain or drizzle, and southeasterly winds of 15–25 km/h that limit radiative cooling. These conditions align with typical early-spring patterns where average October minima hover around 13°C, though stronger southerly flows or clearer breaks could push readings lower toward single digits or allow modest warming. The closely matched market-implied odds between sub-10°C and 19°C+ outcomes reflect trader emphasis on forecast uncertainty in short-range guidance, with resolution hinging on the precise minimum recorded by official stations during the overnight period. Updated model runs and local observations will refine probabilities ahead of the date.
