Recent forecasts from multiple models indicate a highest temperature in Buenos Aires on October 9 most likely between 16–17°C, driven by persistent overcast skies, southeasterly winds advecting cooler maritime air, and light drizzle that limits daytime heating. These conditions follow heavy rainfall on October 7 and a cooling trend, with surface pressure rising and reduced solar insolation keeping maxima below seasonal averages. Minor model differences in cloud thickness, exact wind speeds around 8–10 m/s, and precipitation timing create the tight spread between 16°C and 17°C outcomes, while stronger onshore flow or clearer breaks could push readings toward 15°C or 18°C. Updated runs from agencies like the National Meteorological Service will refine these variables ahead of market resolution.
