Climate Characteristics of Buenos Aires

General Overview

Buenos Aires features a humid subtropical climate. The city experiences four distinct seasons, with hot, humid summers and relatively mild winters. As it is located in the Southern Hemisphere, the seasons are reversed compared to Europe or the Middle East.

Summer and Warm Months (December to February)

Summer in Buenos Aires is hot and often characterized by high, sometimes oppressive humidity. Daytime temperatures range between 28°C and 30°C (82-86°F), though heatwaves can push them above 35°C (95°F). This is the busiest tourist season despite the humidity. Short, intense summer rainstorms (thunderstorms) are very common and help to briefly cool the air.

Winter Season (June to August)

Winter in Buenos Aires is mild and cool, but rarely freezing. Daytime temperatures average around 15°C (59°F), while nighttime lows drop to 7°C-9°C (45-48°F) on average. Grey, rainy days are more common during this season, but snow is an extremely rare event, occurring only once every few decades.

Transition Seasons (March-May and September-November)

Autumn and spring are considered the best times to visit the city. The weather is generally clear and very comfortable for walking (around 20°C to 22°C / 68-72°F). In October and November, the city is filled with the spectacular purple blooms of Jacaranda trees, making the avenues particularly beautiful.
