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.
