If you’re heading to Patagonia in January or February then be prepared for surprising heat in the north, in places like Peninsula Valdés, as well as rain in the south, Tierra del Fuego, for example.
Temperatures dip across the region pretty much from March through to October with nights, especially, proving particularly chilly.
April and May are both thought of as the best months to visit Patagonia due to the colourful autumn foliage and fewer crowds, with northern regions still retaining some warmth against the milder climes of the south.
May, June, July and August are cold and wet in and around Tierra del Fuego with many areas becoming frozen and often inaccessible to tourists.
That said, winter months in Patagonia have plenty of clear blue sky days and less wind but more southerly national parks, such as Torres del Paine National Park and Isla Magdalena, are usually shut.
September and October bring spring to Patagonia, and are also one of the best times to visit if you want to steer clear of the amassing crowds and don’t mind wrapping up against harsh winds.
As temperatures start to rise during November and December popular parks and natural landmarks start to get busy. However, this is a massive area and if you don’t mind sharing, booking well in advance or getting further off the beaten track there are a great many Patagonia adventures to go round.
