Activities to Enjoy in Patagonia During December

Rainfall, Humidity, and Cloud Cover in December
Rainfall in December is moderate across most of Patagonia. The northern Argentine regions (like Bariloche or El Bolsón) are generally drier, while Chilean destinations such as Puerto Varas or Coyhaique experience more rainfall and cloud cover. Southern areas like Punta Arenas or Ushuaia may have intermittent showers and strong winds — especially in the afternoon.
Humidity is usually comfortable, which makes hiking and outdoor activities pleasant. You can expect a mix of sunny days, partial cloud cover, and the occasional rain shower — a perfect balance for exploring.
Climate Variability: What Influences December Weather in Patagonia?
The weather in Patagonia is influenced by powerful natural forces: the Andes mountains, cold ocean currents, glacial fields, and vast steppes all shape the region’s microclimates. Conditions can change dramatically over short distances.
A day that starts sunny in El Chaltén could turn cloudy and rainy by the afternoon. Similarly, Puerto Natales may be clear and calm while Torres del Paine faces high winds just a few miles away.
Understanding these patterns is key to preparing for your trip and choosing the right clothing, gear, and activities.
Cultural Events and Christmas in Patagonia
Experiencing Christmas in Patagonia is unlike anywhere else in the world. Instead of snowy rooftops, you’ll find festive barbecues, artisan markets, and other cultural celebrations held under the summer sky.
In Bariloche, families gather for lakeside dinners and roast lamb.
In Puerto Natales, you’ll find holiday lights and seafood feasts with a local twist.
In rural estancias, Christmas Eve may include live folk music, storytelling, and regional wine.
The combination of holiday warmth and scenic beauty makes for a magical end-of-year celebration.
