Season and Clothing

Summer: December to March

Summer in Buenos Aires is hot and humid with temperatures averaging around 23 degrees Celsius. January and February are the hottest and humid months with many travellers escaping the heat by retreating to the air-conditioned comfort of shopping malls, museums and the El Ateneo library, which is a fantastic hangout in the cool. Another great place to be in summer is Buenos Aires Playa, a series of artificial beaches set up in the city's parks and along the river. Enjoy the sun, cool off in the fountains and revel in the novelty of a beach in Buenos Aires. Many Porteños also vacate the city for the coast during this time, so be aware that some museums and attractions may be closed for the summer. Carnaval may be on a smaller scale than how the Brazilians do it, but nevertheless drummers and dancers still take to the streets in Entre Rios before Lent.

Don't forget: Sunscreen, sunglasses and a hat.
