**Extreme Winds:** Patagonia is famous for its fierce winds, which can reach gale force (70-100 km/h) especially in spring and summer. These winds can make hiking difficult, increase the perceived cold, and stir up dust. Always carry windproof gear.
**Sudden Weather Changes:** Weather in Patagonia can change rapidly, with sunny skies turning to rain or even snow in a matter of hours, particularly in spring and autumn. Be prepared for all four seasons in one day.
**Strong UV Radiation:** Despite often mild temperatures, the UV index can be very high, especially in summer due to the clear air and proximity to the ozone hole. Always wear sunscreen, a hat, and sunglasses.
**Winter Hazards:** During winter (June-August), expect icy roads, heavy snowfall, and potential road closures. Extreme cold can pose hypothermia risks. Check forecasts and road conditions constantly if traveling during this period.
Layering Guide
Due to Patagonia's famously variable weather and persistent winds, a multi-layering system is crucial year-round. Start with a moisture-wicking base layer (synthetic or merino wool). Add an insulating mid-layer like a fleece or lightweight down jacket. The most critical layer is a windproof and waterproof outer shell jacket, even in summer, to protect against sudden squalls and the relentless wind. For legs, convertible hiking pants are good for summer, while waterproof and windproof overtrousers are recommended for cooler months or when rain is expected. Always bring a warm hat, gloves, and a neck gaiter, as heat loss from extremities is significant, especially with wind.
