Antarctica’s temperatures average between 28°F and 44°F (-2°C to 6°C), often surprising visitors with their mildness. Expedition cruises only operate between the Austral summertime months of October to March, providing a far more pleasant climate than the harsh winters. You might even find yourself overheating while trekking uphill through snowy terrain!
However, Antarctica is full of extremes, and strong winds can quickly bring down the temperature with a biting wind chill. This is particularly noticeable when you're out on deck whale watching or admiring the icebergs. Thankfully, with proper preparation – waterproof, windproof outerwear and insulating layers to retain heat – you can stay warm and dry.
