Buenos Aires may be a world-class city and top destination in South America, but it seems everyone in the world already knows that. What everyone really wants to know now about, based on our research (and the very frequently-asked-questions we receive), is: the weather. It's not as riveting as details on the city's best flea markets, maps of architecture you can't miss, or food-porn-worthy photos of steak and pasta, but fine, we're here to give the people what they want! (We have those other things though if you're interested). Here we have for you the type of weather you'll experience each time of year, and what exactly that means for you and your trip to this chic capital city.

Buenos Aires Weather By Season & Month

Because it's in the Southern Hemisphere, the seasons of Argentina are opposite what most of us English-speakers are used to. Overall, temperatures in Buenos Aires throughout the year are considered moderate, but the levels of rainfall and average temperatures vary enough to impact the type of trip and crowds you'll experience.

Spring (Mid-September through mid-December)

Weather in September, October, November, December.

Average Temperatures: Moderate temperatures range from the upper 60s to mid-70s in the day, dropping to low 60s at night.

Spring (like Fall) sees the highest amount of rainfall (usually short, sporadic showers). The weather is perfect for outdoor events most days, and the city gets little hotter and a little stickier as summer approaches.

Summer (Mid-December through mid-March)

Weather in December, January, February, March.

Average Temperatures: Daily reaching highs in the low 80s, cooling off only slightly in the evenings.

As it gets hotter, the weather gets a bit humid. Everything is open, and this is a great time if you're hoping to also sneak down to the colder Southern part of the country.

Fall (Mid-March through mid-June)

Weather in March, April, May, June.

Average Temperatures: Temperatures range from the upper 60s to the mid-70s, dropping lower at night, especially as the season goes on.

Like Spring, Fall is the other rainy season. The temperature drops slowly with each month as it rains on and off.

Winter (Mid-June through mid-September)

Weather in June, July, August, September.

Average Temperatures: Highs are usually in the 50s, lows can drop a bit. Evenings and mornings are always noticeably cooler.

The coldest season. You'll get a wind chill in certain parts of the city, being a port and all, but you won't have the rain of the slightly warmer Fall or Spring. It gets extremely cold in other parts of the country at this time.


Peak Tourist Seasons

Summer is the most popular time to visit. Prices increase and things begin to book full as everyone flocks to the city. Cruise ships arrive, people from the colder areas come to visit, and there are outdoor events taking place almost every day. (Christmas, New Years & Abierto de Buenos Aires in February pull in ).

Spring is the second most popular time to visit due to the warmer weather, but slightly less crowded (and expensive) than summer.

Fall and Winter are the low season, as visitors avoid the dropping temperatures. Prices are lower, and you'll find the best deals beginning at the end of Summer and Fall in preparation.


The Best Time to Visit

Obviously this is a very subjective one, but we love Spring and Fall (especially the tail ends closer to Summer). The streets are bustling but you can still do everything you want without waiting forever or planning far in advance. If you catch the ends of either season closer to Summer, you probably won't see too much rain, but you'll still be getting the cheaper costs that come with it not being Summer. Spring will be more crowded and expensive than Fall, but it usually has nicer weather.

Budget travelers will find a happy medium in Fall, before the weather is too chilly but prices and crowds have already dropped to "low season" levels. This is when we visited most recently, and even though we experienced rain it never interrupted our plans.


What to Pack

Your Buenos Aires packing list will include anything you would take to a stylish, modern city, just catered to the season. In general, that means to make sure to have nicer outfits if you plan to go out in the evenings, but can wear anything you want during the day. You'll probably do a decent bit of walking as you sightsee, but most activities will be city exploring versus outdoorsy and nature excursions.

If you're visiting in the summer, bring your warm-weather best. We recommend a light jacket for the evenings, but you'll hardly need it. Plan on spending a decent amount of time in the sun, and make sure to check if your hostel/hotel has air conditioning. Hats, sunglasses, everything. Even though there is no beach, locals often lay out in parks on sunny days so you may want to bring a bathing suit anyways.

If you're visiting in the Spring or Fall, you'll need to pack the most. Often moderate, the weather can also be very back and forth. Sometimes you'll get that hot in the sun, freezing in the shade experience, and you may have alternating days of chilly and overcast (or rainy) with sunny and summer-like. For this, we recommend layers. Layers, layers, layers. When it rains, you'll want decent boots of closed-toe shoes, a coat with a hood and full pants. You'll probably also want a thick sweater for when it gets windy. But, when it's sunny you'll start stripping down to your tee-shirt and sometimes that full pants will feel like too much. To avoid feeling like you need to return home to change, utilize layers. In the evenings, you'll definitely want a jacket but don't be surprised if you find a use for a sundress or shorts some days as well. Also, bring an umbrella because when it starts raining vendors will charge you and arm and a leg, but when it's sunny the umbrellas for sale are nowhere to be found.


How the Weather & Seasons Will Impact Your Plans

In the Spring & Summer, everything is open. Everything! But, as stated above, it will be crowded and you may have to settle for hotels or tour times that aren't your first choice if you aren't a huge planner.

If you visit in the Fall or Winter, most things will be open but outdoor markets, parks, and walking tours will become less enjoyable when it rains (obviously) and very rarely some of these things will be cancelled (most carry on no matter what, but we don't want any surprises). If you're all about aimlessly wandering the city by foot, this maybe isn't the time for you.

If you plan to visit elsewhere in the country, then the seasons will matter more. For starters, Iguazu Falls are known for being much more beautiful (and bigger) in the Winter and Fall (wet seasons), but Patagonia and colder spots are often preferred in the Spring & Summer because the weather gets shockingly cold in the winter (and sometimes extreme conditions will lead to cancellations).
