**Forecast models from multiple sources indicate a high temperature in Buenos Aires on October 12 most likely in the 16–17°C range, aligning with the market’s leading 40% implied probability for 17°C.** Persistent easterly to southeasterly flow, combined with extensive cloud cover and periods of light drizzle or overcast conditions, is limiting daytime warming under the current spring setup. Recent model runs show modest thermal recovery from cooler air earlier in the week, with highs constrained near or slightly above seasonal norms for mid-October. Key variables include the exact timing of any breaks in cloudiness and boundary-layer moisture, which could shift the daily maximum by 1–2°C. Updated guidance expected overnight and early on the 12th will provide the final observational constraints before market resolution.
