Weather Warnings

**Strong Winds:** Patagonia is renowned for its intense, persistent winds, especially during summer. Be prepared for gusts exceeding 100 km/h, which can impact hiking stability and feel much colder.

**Rapid Weather Changes:** Mountain weather can shift dramatically within hours. Sunny mornings can quickly turn into cold, rainy, or even snowy afternoons.

**High UV Index:** During summer, even on cloudy days, the UV radiation can be very strong. Always apply high-SPF sunscreen, wear sunglasses, and a hat.

**Winter Hazards:** From May to September, expect heavy snow, icy conditions, and sub-zero temperatures. Backcountry travel requires specialized equipment and experience; avalanches are a risk in some areas.

**Sudden Storms:** Convective storms can develop quickly, bringing heavy rain, hail, and lightning, particularly in the summer and shoulder seasons.

Layering Guide

Layering is paramount when visiting Parque Nacional Lanín due to its unpredictable mountain climate. Start with a moisture-wicking base layer (synthetic or merino wool) to keep sweat away from your skin. Add an insulating mid-layer like a fleece jacket or lightweight down vest for warmth. The critical outer layer should be a waterproof and windproof shell jacket to protect against the region's strong winds and sudden downpours. Depending on the season, you might also need insulated mid-layer pants or waterproof over-pants. Always bring a warm hat, gloves, and a buff/scarf, as even summer evenings can be chilly, and winds can make any temperature feel colder.
