Recent forecasts from multiple models indicate a high near 17–18°C for Buenos Aires on October 11 under overcast skies and light southerly to southeasterly flow. Persistent cloud cover from a broad trough and cooler maritime air advection has suppressed daytime heating after several days of below-normal maxima, keeping trader-implied odds tightly split between the two leading outcomes. Light winds and minimal precipitation risk limit mixing or warming, while model spreads in boundary-layer temperature reflect modest uncertainty in exact peak values. Historical October averages near 20°C provide context for the current cooler regime. Updated model runs and surface observations in the next 24–48 hours will likely narrow the distribution ahead of resolution.
