What is the weather like in Argentina in April?

April in Argentina means shorter days, cooler nights, and the start of fall colors across the country. In Buenos Aires, the parks turn golden, and the pace of the city feels a little more relaxed. 

Further south, Patagonia starts to wind down for the season, with fewer crowds and colder mornings that make hiking more challenging. In the north, it’s still warm enough for comfortable travel, and places like Iguazú Falls remain accessible. Mendoza’s vineyards are in harvest mode, and it’s one of the best times to visit for wine tastings and valley views. Since summer tourism has tapered off, you’ll find fewer people at popular spots and better deals on hotels and transport. 

You’ll want to pack layers, especially if you’re crossing regions. If you’re after lower prices, beautiful landscapes, and manageable weather without peak-season crowds, April hits a pretty sweet spot across much of Argentina. This can be a great time to plan your Argentina itinerary.
