Recent model consensus from sources including GFS and regional forecasts points to a maximum of 17–18°C in Buenos Aires on October 1, driven by southwesterly flow and extensive low- to mid-level cloud cover that limits insolation during peak heating hours. Late September observations show daytime highs near 19°C under partly cloudy skies, but an approaching frontal boundary and increased marine influence from the South Atlantic are expected to suppress temperatures by 1–2°C. Historical early-October averages hover around 19–20°C, yet the current synoptic setup favors values closer to seasonal norms or slightly below. With resolution only two days away, traders are weighting the latest deterministic and ensemble runs heavily, as minor shifts in cloud timing or wind direction could still nudge the daily maximum across the 16–18°C thresholds.
