Before diving into all of the different things to do in Buenos Aires in September, let’s take a look at the overall vibe and weather that this month brings.
🤔 Is September a Good Time to Visit Buenos Aires?
Yes! September is a great time to visit Buenos Aires, especially if you want to experience the city as it transitions from winter into spring. The beginning of the month can still be a little chilly, but the weather gradually gets warmer and you’ll start seeing more people enjoying the city’s parks and outdoor spaces.
Spring officially begins on September 21st, which is also Día de la Primavera in Argentina. This is a fun time to be in Buenos Aires, with locals heading outdoors to celebrate, especially around Bosques de Palermo.

☀️ What is the Weather Like in Buenos Aires in September?
Buenos Aires in September is a bit of a transition month, so you can get a mix of cooler mornings, comfortable afternoons, and occasional rain. Early September can still feel like winter, while the second half of the month generally starts feeling much more spring-like.
Spring is also one of the wetter seasons in Buenos Aires, although rain doesn’t necessarily mean you’ll lose an entire day to bad weather. We’d recommend packing layers, including a light jacket or sweater for the cooler mornings and evenings, plus clothes that you can comfortably wear when temperatures warm up during the day.
