Buenos Aires has a temperate climate with four distinct seasons, meaning your packing list depends entirely on when you go. The live forecast above gives today’s conditions, but for trip planning you need to know that summer (December–February) is hot and humid, while winter (June–August) is cool and damp.
What is the best time to visit Buenos Aires?
For Canadian travellers, the sweet spot is spring (October–November) and autumn (March–May). These shoulder months offer warm, sunny days in the low 20s °C, far fewer crowds than peak summer, and lower accommodation rates. Snowbirds often target July–August (their winter, our summer) to escape Canadian cold, but be prepared for highs around 15°C and occasional rain. March break falls in early autumn, when the city is still pleasant with average highs near 26°C – ideal for sightseeing without the oppressive humidity of January.
What should I pack for Buenos Aires?
If you’re visiting between December and February, pack light cottons, a rain jacket for sudden thunderstorms, and a light sweater for air-conditioned restaurants. For June–August, bring layers – a medium-weight jacket, scarf, and closed shoes – as temperatures can dip to 8°C at night. Year-round, comfortable walking shoes are essential for exploring the city’s wide avenues and historic neighbourhoods.
Does Buenos Aires get cold enough for a winter coat?
Yes, especially in June–August when overnight lows can hit 5°C. A medium-weight jacket or fleece is sufficient for daytime, but you’ll want a warmer layer for evenings, particularly if you plan to be out late.
What is the weather like in Buenos Aires in December?
December is the start of summer, with average highs around 29°C and high humidity. Expect occasional afternoon thunderstorms. It’s a popular time for locals to vacation, so book accommodation early and pack light, breathable clothing.
Is Buenos Aires humid all year?
Humidity is consistently high, ranging from 60% in winter to 80% in summer. The dampness can make summer heat feel more intense and winter chill feel raw. A compact umbrella is a good idea any month.
