Is December Right for You?

Weigh the advantages and considerations before booking

Advantages
  • + Peak penguin chick season. Adelie, Gentoo and Chinstrap chicks hatch and waddle in creches. Photography gold. Snap away.
  • + Solid sea-ice lets ships reach the rarely visited Ross Sea side and Snow Hill Emperor penguin colony. Go now.
  • + Midnight sun removes all time pressure. You can zodiac-cruise at 2 am under blazing sunshine. No rush.
  • + Whales are back in force. Humpback, Minke and the season's first Orca pods feast on krill swarms. Spectacular.
  • + Icebergs are freshly carved and bluest of the year, before January summer algae tints them. Catch the color.
Considerations
  • It's the most expensive window. Every berth sells out 12-18 months ahead
  • Katabatic winds can spike above 38 knots (70 km/h) and ground helicopter flights for days. Pack patience.
  • You share deck space with 200-500 other passengers. Solitude is almost impossible in December. Expect crowds.

Best Activities in December

Top things to do during your visit

Ross Sea Historic Huts & Icebreaker Voyages

Only December-January ice conditions let strengthened ships reach Shackleton's and Scott's preserved huts, plus the world's largest Adelie penguin rookeries at Cape Adare. Days are 24-hour bright, so landings aren't rushed and you can photograph huts with alpenglow at 3 am. Shoot late.

Booking Tip: Book 14-18 months out. Look for voyages carrying under 200 passengers to maximize landing time. Helicopter-equipped vessels give Plan B if sea-ice shifts. Plan ahead.
Snow Hill Island Emperor Penguin Colony Fly-Cruise

Emperor chicks are fledging. Helicopter from the ship lands you within 1 km (0.6 mi) of 4,000 pairs. December's stable floes mean the colony is still tight, chicks squealing like rusty gates. Listen close.

Booking Tip: Choose operators with two helicopters. Weather can ground one for days. Trips are 11 days, fly from Punta Arenas to ship at King George Island, shaving 2 sea days off the Drake. Save time.
Sea-Kayak Among Icebergs in Wilhelmina Bay

Water is mirror-calm, brash ice at 0°C (32°F) but kayaks put you eye-level with curious leopard seals. Midnight sun means glassy reflections of bergs last all 'night'. No wind chop before afternoon katabatics kick in. Paddle early.

Booking Tip: Dry-suit certification required by most ships. Reserve kayak slot when you book cruise. Only 8-12 spots per sailing. Act fast.
Citizen-Science Penguin Count on Deception Island

Researchers tag chicks. Passengers help weigh them with spring scales. December chicks are football-sized and vocal, great for kids or data-minded travelers. Volcanic black beach steams when cold air hits geothermal vents. Feel the heat.

Booking Tip: Ask if your vessel partners with Polar Citizen Science Collective. You'll get data sheets and a follow-up report after you go home. Stay involved.
Polar Plunge & On-board Sauna Circuit

December water is -1°C (30°F). Ships heat outdoor saunas to 90°C (194°F) so you can oscillate between extremes. Med staff monitor for after-drop. Once you dry off, midnight sun decks are warm enough for T-shirts. Brave the swing.

Booking Tip: No extra fee but sign-up early. Slots fill when everyone wants bragging-rights footage. Beat the rush.

December Events & Festivals

What's happening during your visit

21 December
Midwinter Day Broadcast (for expedition staff)

Ship crews exchange live radio greetings with Antarctic bases on 21 Dec. Passengers often invited to listen in as McMurdo, Rothera and Concordia trade music requests and jokes. A quirky slice of station life. Tune in.

Mid to Late December
Snow Hill Emperor Chick Hatching Peak

Last 2 weeks of December see most chicks on their feet. Photographers get grey-fluff balls against adults' orange throats. Guides limit group to 15 people at a time to avoid stressing birds. Respect the limit.

Essential Tips

Insider knowledge and common pitfalls to avoid

Insider Knowledge
Ask bridge officers for 'ice watch' schedule. Standing a 2 am watch with them is legal and memorable. Stay awake. Download StarWalk before departure. Sun never sets so apps show real-time satellite passes against pale sky. Track the sky. Ships run on Chilean time. Sync watch to ship, not to Ushuaia port when you embark to avoid missing zodiac calls. Reset early. Bring a 2 m (6.5 ft) lightweight cloth tape measure. Guides need chick flipper lengths; you'll get credited in research notes. Measure up.
Avoid These Mistakes
Booking flights home before 2 pm on disembarkation day. Drake delays can push arrival 24-36 hours. Buffer wisely. Walking onto penguin highways (brown-grey paths in snow). One careless step can crush an egg. Watch your feet. Skipping the ship's provided rubber boots. Your fancy hiking boots have poor traction on wet steel gangways. Wear the ugly ones.
