Best time to visit
Buenos Aires sits in the Southern Hemisphere: summer runs December to February and winter June to August, the reverse of the northern calendar. When you travel changes everything from what to pack to which day trips are worth it. Here is a month-by-month overview of weather, crowds and typical prices.
Mild temperatures, manageable crowds and comfortable conditions for walking the city and taking day trips; jacarandas bloom across Buenos Aires in late October.
Long, warm days suit the Delta and river life, though January and February bring high humidity, heat and many locals away on their own holidays.
Argentine winter school holidays push up domestic travel and prices in early-to-mid July, even though the city itself stays mild rather than cold.
