**Forecast consensus points to a mild spring day in Buenos Aires on October 3, with official and ensemble models from sources like the Servicio Meteorológico Nacional and international guidance showing daytime highs most likely between 15–17 °C under cloudy skies and scattered showers.** Northeasterly winds and high humidity are expected to limit daytime heating, while any breaks in cloud cover or delayed frontal passage could push readings toward 18–19 °C; conversely, heavier rain or stronger southerly flow would cap them nearer 14–15 °C. The tight clustering of market-implied probabilities around 13–20 °C reflects this model spread and typical early-October variability in the region, where spring transitions often produce 2–4 °C day-to-day swings. A potentially strong El Niño pattern may enhance moisture but is not yet exerting a dominant temperature signal. Updated model runs and official briefings over the next 48 hours will be the key catalysts for any sharp shifts in trader positioning.
