Weather Warnings

Patagonian Winds: Be prepared for strong, persistent winds year-round, especially in spring and summer (November-February), with gusts frequently exceeding 70-80 km/h. They can make hiking challenging and increase the perceived cold.

Sudden Weather Changes: Mountain weather is unpredictable. Conditions can shift rapidly from sunny to rainy or snowy, even within the same day. Always carry layers.

UV Radiation: Due to clear skies and the ozone layer thinning over Patagonia, UV radiation is very high, particularly in summer. Use high-SPF sunscreen, wear sunglasses, and a wide-brimmed hat.

Winter Conditions: From May to September, expect snow and ice, potentially leading to road closures and requiring snow chains for vehicles. Backcountry travel in winter requires expertise and proper gear.

Hydration: The dry Patagonian air and constant wind can lead to dehydration quickly. Drink plenty of water, even on cool days.

Layering Guide

Dressing in layers is paramount for Aluminé's variable Patagonian climate. Start with a moisture-wicking synthetic or merino wool base layer to manage sweat. Add an insulating mid-layer like a fleece or lightweight down jacket for warmth. The crucial outer layer should be a high-quality windproof and waterproof shell jacket and pants to protect against wind, rain, or snow. Always carry a warm hat, gloves, and a neck gaiter, even in summer, as conditions can change rapidly or temperatures drop in the evenings. Adapt the thickness of your layers based on the season and activity.
