Weather Warnings

Extreme and unpredictable winds are common year-round, often reaching gale force. Always check forecasts and secure belongings.

Weather can change rapidly from sun to rain, sleet, or snow within hours, regardless of the season. Always dress in layers and carry waterproof gear.

Even on cloudy days, UV radiation can be strong, especially in summer. Wear sunscreen, sunglasses, and a hat.

Hypothermia risk: Cold temperatures combined with wind and precipitation can lead to rapid heat loss. Always be prepared for cold conditions.

Icy conditions: In winter and early spring/late autumn, roads and trails can be slippery due due to ice and packed snow.

Layering Guide

Dressing in layers is paramount for Ushuaia's variable climate. Start with a moisture-wicking base layer (merino wool or synthetic) to manage sweat. Add an insulating mid-layer like fleece or a light down jacket for warmth. The crucial outer layer should be a high-quality waterproof and windproof shell jacket and pants to protect against wind, rain, and snow. Always include a warm hat, gloves or mittens, and a scarf or neck gaiter. Waterproof hiking boots with good ankle support are essential for all seasons.
