During these periods, you'll find comfortable temperatures, typically ranging from 60°F to 80°F (15°C to 27°C), with moderate humidity and less rainfall. This makes it ideal for exploring the city's outdoor attractions, such as the waterfront along the Uruguay River or enjoying a stroll through the downtown area. Travelers seeking a relaxed experience without extreme heat or cold will appreciate these seasons.
Summer, from December to February, can be quite hot and humid, with temperatures often exceeding 90°F (32°C), and occasional thunderstorms. While suitable for those who enjoy warm weather, it might be less comfortable for extensive sightseeing.
