Buenos Aires in December
Not the best time
December brings holiday excitement but also the return of summer heat and crowds. It's festive and fun but you'll pay premium prices and start feeling the heat that peaks in January.
Weather
December starts the summer heat buildup with temperatures climbing to 27°C and humidity beginning to feel oppressive. Late in the month, the heat becomes more intense as locals prepare for summer vacation season.

All Months
March through May delivers perfect weather — warm days, cool nights, and fewer crowds than summer. The jacaranda trees bloom purple along every street, making even mundane walks feel magical. September through November works just as well, with spring energy and outdoor tango shows returning to the plazas. Summer (December-February) gets brutally hot and humid, plus half the city evacuates to the coast. But if you can handle the heat, hotel prices drop and you'll have restaurants to yourself. Winter (June-August) stays mild by Northern Hemisphere standards — think 50-60°F — but the gray skies can feel endless. The upside? Theater season peaks, tango shows move indoors to intimate venues, and you'll experience the city like a local. Avoid January if possible — it's peak tourist season, everything costs more, and many family-run restaurants close for vacation. Plan around the seasons, not the calendar.
