**Forecast models from sources like the National Meteorological Service and international ensembles indicate a minimum temperature near 14–15°C for Buenos Aires on October 6, driven by persistent easterly flow, widespread cloud cover, and limited nocturnal radiative cooling under spring conditions.** This setup favors overnight lows in the mid-teens Celsius, consistent with climatological norms for early October where the coolest hour typically occurs near dawn. Market-implied odds remain closely balanced between sub-10°C and 19°C+ outcomes because of typical short-range forecast uncertainty in boundary-layer mixing and any late adjustments in cloud or wind fields. Traders appear to weigh the possibility of stronger cooling under clearer breaks or enhanced warming from advection against the current consensus favoring moderate temperatures. Updated model runs and official briefings over the next 48 hours will likely narrow the range as the event approaches.
