Antarctica in December: Midnight Sun, First Chicks and Peak Summer
Of all the months to visit Antarctica, December is the one that genuinely feels like summer — and antarctica in december delivers a combination of conditions that no other month can quite match. Near-continuous daylight. The first penguin chicks of the season. The Antarctic Circle becoming accessible as the sea ice retreats. Whale numbers building by the week. And the extraordinary experience of photographing icebergs in golden light at midnight. This is summer at the bottom of the world, and it’s remarkable.
December sits squarely in the heart of the Antarctic cruise season, which runs from November through March. It builds on the pristine early-season conditions of November — the fresh snow, the dramatic icebergs — and adds the wildlife theatre of chicks and increasing whale activity that peaks in January and February. For many travellers, it’s the best of both worlds. Our best time to visit Antarctica guide compares all five months, and our Antarctica weather by month breakdown provides full context.
Antarctica in December: Weather and Temperatures
December brings the warmest temperatures of the early-summer period. On the Antarctic Peninsula, averages run from −1°C to +2°C (30°F to 36°F), and in sheltered inlets on sunny days, you can occasionally see the thermometer touch +5°C or even slightly above. On deck with any kind of wind, it still feels cold — apparent temperatures with wind chill can drop to −5°C or below — but the difference between November’s −2°C to 0°C and December’s −1°C to +2°C is noticeable. You’ll be comfortable with slightly fewer layers.
Precipitation in December tends to be a mix of snow and light rain as temperatures hover around freezing. Snow showers are shorter and less frequent than in November, and clear sunny days are more common. The extended daylight — 20–24 hours around the solstice — means that when conditions are good, they’re good for an extraordinary number of hours. Expedition teams maximise this: Zodiac cruises at 11pm in flat light are not unusual in December.
Sea ice in December is retreating steadily from its November maximum. By mid-December, most Peninsula landing sites are accessible without significant pack-ice navigation, and by late December the Antarctic Circle (66.5°S) becomes reachable for ships with appropriate ice ratings. This is a significant development: the Circle is a symbolic and practical milestone that very few expedition cruises crossed in early November. For packing advice whatever the month, see what to pack for Antarctica.
The December Solstice: 24-Hour Daylight
The summer solstice falls on 21 or 22 December each year in the Southern Hemisphere. At this point, locations within the Antarctic Circle experience full 24-hour daylight — the sun circles the horizon without setting. On the Antarctic Peninsula, which lies just north of the Circle at its narrowest, you get approximately 20–22 hours of direct sunlight with a brief twilight that barely qualifies as dusk. At the South Pole, the sun has been continuously above the horizon since September and will remain so until March.
For travellers, this means you can be active at any hour. Wildlife doesn’t follow a conventional schedule — a humpback whale bubble-netting at 1am is just as visible as one at 1pm, and penguin colonies are busy around the clock. The practical upshot is that expedition schedules can be more flexible, taking advantage of calm early-morning conditions or late-evening light. Many passengers find the continuous daylight initially disorienting — blackout curtains or an eye mask is essential kit — but within a day or two most people adapt and start treating it as a licence to stay up as late as the naturalists will allow. For more on this extraordinary phenomenon, see our Antarctica daylight hours guide.
Wildlife in Antarctica in December
December is when Antarctica’s wildlife season shifts from anticipation to action. The penguin chicks begin hatching in mid-to-late December on the Peninsula — Gentoos first, followed by Adélies and chinstraps. In early December you’ll find adults on nests in advanced incubation; by late December, the first fluffy grey chicks are demanding food from exhausted parents who must make near-constant feeding trips to the sea. The contrast between the adults — sleek, upright, and efficient — and the chicks — round, grey-brown, and perpetually indignant — is one of the great visual treats of Antarctic travel.
Whale sightings build through December. Humpbacks, minkes, and the occasional orca are present in increasing numbers as they follow the krill blooms south. By late December, multi-whale sightings in a single day are becoming common. Seals are highly visible throughout — Weddell seals on remaining ice floes, leopard seals patrolling penguin colony edges, and fur seals beginning to establish beach territories. Seabirds are particularly abundant: albatrosses, petrels, skuas, and sheathbills follow the ship and provide constant background action.
The Falkland Islands, if your itinerary includes them, are at peak breeding season in December — Rockhopper and Magellanic penguins with eggs and early chicks, Black-browed albatross colonies in full swing, and the dramatic coastal scenery at its most vivid green. South Georgia in December has King penguin colonies with large brown chick creches alongside newly hatched smaller chicks, and the elephant seal beach scenes are extraordinary. For a species-by-species breakdown of when to see specific wildlife, see Antarctica wildlife and best time to see penguins in Antarctica.
Ice Conditions and Landing Sites in December
Ice in December presents a progressive story through the month. Early December looks more like late November — substantial ice still in some channels, large dramatic icebergs everywhere, some landing sites requiring careful ice navigation. By late December, the ice has retreated significantly and the range of accessible landing sites is at its broadest of the season to that point. The Antarctic Circle becomes navigable for ice-rated ships in late December, allowing the symbolic and photogenic crossing that many travellers specifically target.
The number and quality of icebergs in December is extraordinary. The summer’s warmth has begun to calve new ice from glaciers and ice shelves, adding to the population of older bergs that have been drifting since winter. Colours range from brilliant white through translucent blue to deep jade green (caused by algae in ice that has been submerged and compacted over centuries). The blue is the most striking — caused by light scattering in dense, ancient ice — and December’s low-angle sun turns these blues almost electric. Our Antarctica regions guide covers the key landing sites accessible in December.
December Cruise Prices and Booking
| Period | Relative Price | Conditions | Availability |
|---|---|---|---|
| Early Dec (1–10) | Moderate | Transitioning from Nov, ice clearing | Good selection |
| Mid Dec (11–20) | Moderate–High | First chicks, clearing ice | Popular, book early |
| Dec 21–31 (Solstice/NY) | Peak | 24hr daylight, active colonies | Books out fastest |
December is a step up in price from November but generally slightly below January peak. The Christmas and New Year period (roughly December 20–January 5) is the most expensive window of the entire season — demand from travellers wanting a once-in-a-lifetime holiday experience pushes prices up, and ships depart full. If December is your month, early December offers the best value, and late December requires booking 18+ months ahead for preferred cabin categories. See Antarctica trip cost for the full pricing breakdown and when to book for timing strategy.
December Activities and Experiences
The core expedition programme in December is excellent in every respect. Zodiac cruising through iceberg fields is available throughout, and the improving conditions through the month progressively open up more areas. Kayaking becomes more consistently available from mid-December as ice conditions stabilise. Camping on the ice — a magical experience offered by some operators — runs in December for appropriate weather windows, and sleeping under the perpetual Antarctic twilight in a bivouac on the Peninsula ice is a story you’ll be telling for decades.
The ship’s lecture programme in December typically covers glaciology (highly relevant as you watch calving events), marine biology (the krill ecosystem that supports everything from penguins to blue whales), ornithology (albatrosses and petrels), and Antarctic history (the Heroic Age expeditions of Scott, Shackleton, and Amundsen). These lectures transform what you’re seeing from interesting wildlife into a complex ecological story. Our things to do in Antarctica guide covers the full activity menu.
December vs Adjacent Months
- November vs December: November has pristine snow and courtship; December adds first chicks and 24-hour solstice daylight. November is cheaper; December is worth the premium if chick-watching matters to you.
- December vs January: January has more chicks, warmer temperatures, and peak whale activity. December has more dramatic ice, the solstice experience, and slightly lower prices than peak January. If the midnight sun is a priority, December is the only month where it’s absolutely guaranteed around the solstice.
- December vs February: February has the best whale watching and lower prices, but misses the solstice and the first chicks. The two months suit different priorities.

Frequently Asked Questions
Is December a good time to go to Antarctica?
Yes — December is excellent. You get near-continuous daylight around the solstice, the first penguin chicks of the season, improving ice conditions through the month, building whale activity, and access to the Antarctic Circle by late December. It combines elements of early-season drama with peak-season wildlife.
What wildlife can I see in Antarctica in December?
Penguin courtship continues into early December, with first chicks hatching from mid-month. Humpback, minke, and occasional orca whales are present in increasing numbers. Seals are active on ice and beaches, and seabirds are abundant. By late December colonies are highly active with both incubating adults and new chicks.
How many hours of daylight does Antarctica have in December?
Around the December 21 solstice, the Antarctic Peninsula has approximately 20–22 hours of daylight with a brief twilight. At locations south of the Antarctic Circle, the sun does not set at all for several weeks either side of the solstice. Bring an eye mask and blackout curtains for your cabin.
What temperature is Antarctica in December?
Average temperatures on the Antarctic Peninsula in December range from −1°C to +2°C (30°F to 36°F). Wind chill can reduce apparent temperatures significantly on exposed decks or Zodiacs. Sheltered inlets on sunny days can occasionally reach +5°C or slightly above.
Can I reach the Antarctic Circle in December?
Yes, by late December. As the sea ice retreats, the Antarctic Circle becomes accessible to ice-rated expedition ships. Not all itineraries include the Circle — check with your operator — but late-December departures have the best chance of a Circle crossing outside of January.
How does December compare in price to January?
December is generally slightly cheaper than January, except for the Christmas/New Year period (roughly December 20–January 5) which is the most expensive window of the season. Early December offers the best value within the month.
Are penguin chicks visible in December?
Yes — from mid-to-late December. Early December has adults in late incubation; by mid-December the first chicks appear on the Peninsula, and by late December colonies have a mix of recently hatched chicks and incubating adults. January has the largest number of chicks.
What itineraries work best for December in Antarctica?
Classic Peninsula itineraries (10–12 days), South Georgia and Peninsula combined (18–22 days), and Antarctic Circle crossings all work excellently in December. The combined itinerary with South Georgia is particularly rewarding as both sites are at peak breeding activity simultaneously. See Antarctica cruise itineraries for options.
Final Thoughts
Antarctica in december is one of the most compelling times to make this trip. The combination of near-perpetual daylight around the solstice, the first chicks of the season, the progressive opening of the ice as the month advances, and the building whale activity creates a destination that changes dramatically from week to week within a single month. It’s expensive in the Christmas window, genuinely excellent value in early December, and always breathtaking.

Our Antarctica expedition ships guide will help you choose the right vessel for a December cruise. Whatever you decide, Antarctica in summer is one of the great travel experiences of a lifetime.
The Drake Passage in December
Your December voyage begins with the Drake Passage crossing from Ushuaia, and December conditions in the Drake are generally slightly calmer than November or March — though “calmer” in the Drake is a relative term. The westerly winds that funnel between Cape Horn and the South Shetland Islands can generate 4–6 metre swells at any time of year, and the two-day crossing each way is an experience in itself. The albatrosses that follow the ship — wandering albatrosses with three-metre wingspans banking effortlessly in the wind while the ship rolls — are unforgettable, and the slow building of anticipation across two days of open ocean creates an arrival at Antarctica that no other mode of transport can replicate.
Fly-cruise options are available for some December departures: fly from Punta Arenas over the Drake to King George Island, board your ship there, and cruise back to Ushuaia. This eliminates one Drake crossing and is popular with travellers for whom the sea crossing is a concern. In December, however, the Drake is at its most navigable relative to other months, and many veteran Antarctica travellers specifically prefer the sea crossing for the full experience it provides. See our Drake Passage guide and flights to Antarctica for both options in detail.
Photography in Antarctica in December
December is exceptional for photography. The light quality around the solstice is unlike anything available at other latitudes: 20+ hours of sun means the golden hour at each end of the day is extended to multiple hours, and the rest of the daylight is bright without being bleached. Iceberg colours — blue, green, white — are at their most saturated in the clear polar air, and penguin colonies provide constant close-range wildlife subjects. If you’ve ever seen a dramatic Antarctica photograph, odds are good it was taken in December or January.
Practically: bring a weather-sealed camera body, multiple batteries (cold drains them rapidly — keep spares in an inner pocket), and more memory cards than you think you need. A mid-range telephoto (200–400mm equivalent) is ideal for penguins at colony range, while a wide-angle is essential for landscape and iceberg shots from Zodiacs. The ship will have an onboard photo guide for most operators; these are genuinely useful resources, particularly for people new to cold-weather photography.
Responsible Travel in December
December’s increasing visitor numbers make responsible travel principles particularly important. IAATO (the International Association of Antarctica Tour Operators) sets strict guidelines: no closer than 5 metres to wildlife, single-file walking in colonies to avoid disruption, biosecurity decontamination of boots before every landing to prevent the introduction of non-native species. These aren’t bureaucratic obstacles — they’re the reason Antarctic wildlife is still so extraordinarily habituated to humans. A Gentoo penguin that walks between your legs while you hold very still is one of the highlights of any trip, and that habituation is earned by decades of respectful visitor management.
The guidelines also protect you: a leopard seal hauled out on a beach looks inactive but can move with surprising speed, and colony penguin highways through your path need to be respected on their own terms. Your expedition team will brief you thoroughly before every landing. Follow the guidelines and you’ll have a richer experience — the wildlife comes closer when you’re calm and respectful. For more on planning responsibly, see our Antarctica for every traveller guide and Antarctica facts.
December Practical Planning
Book Ushuaia accommodation for at least two nights before embarkation. Flight delays on the Buenos Aires–Ushuaia route are common, and the only buffer between a delayed flight and a missed ship is those extra days. Most operators recommend arriving in Ushuaia by early afternoon on embarkation day; anything later is cutting it fine. The city has excellent accommodation at various price points, good food (lamb, king crab, and a surprisingly robust wine scene given the latitude), and a frontier atmosphere that makes an appropriate prologue to the voyage.
For trip insurance: Antarctica-specific coverage is essential. Standard travel insurance often excludes polar regions or emergency evacuations from remote locations. Look specifically for coverage that includes medical evacuation from the Southern Ocean, trip cancellation for weather-related delays, and gear coverage for expensive camera equipment. Our Antarctica travel tips guide covers insurance specifics in detail. For how to get to Ushuaia from your home country, see how to get to Antarctica.
The Best December Itineraries
A standard Peninsula cruise in December runs 10–12 days from Ushuaia, covering the South Shetland Islands (King George, Deception, Half Moon Islands), the Antarctic Peninsula proper (Paradise Harbour, Neko Harbour, Lemaire Channel, Petermann Island, Marguerite Bay on longer itineraries), and the Drake crossing each way. This gives you approximately 6–8 days of actual Antarctic time, with 2–3 landings or Zodiac cruises most days. For the South Georgia and Falklands addition, allow 18–22 days.
The Antarctic Circle crossing itinerary — targeting the 66.5°S line in late December — typically runs 12–14 days and requires either an ice-strengthened vessel or exceptionally favourable ice conditions. Not all itineraries guarantee the crossing; check the operator’s language carefully, as some promise to “attempt” the Circle while others guarantee it weather and ice permitting. See Antarctica cruise itineraries and best Antarctica cruises for specific itinerary recommendations and Antarctica cruise season for the full seasonal calendar.
Health and Fitness for a December Antarctica Cruise
Antarctica in December requires a moderate level of physical fitness. Zodiac boarding and disembarking involves stepping over an inflatable tube onto a moving tender — not physically demanding, but requiring balance and confidence. Shore landings typically involve a short walk over rocky, sometimes snowy, terrain and standing for extended periods. Kayaking add-ons require paddling endurance. None of this is extreme, but it’s not a passive cruise-ship experience either. Operators generally specify a minimum fitness level in their terms and conditions; read these carefully if fitness is a concern, and consult your GP before booking if you have any health conditions that might be relevant to cold-weather exertion.
Altitude is not a factor — Antarctica’s highest points are in the remote interior, and the Peninsula and islands you’ll visit are at or near sea level. The main health considerations are cold exposure, seasickness (for the Drake crossing), and the minor injuries associated with rocky terrain landings. All expedition ships carry a doctor and a medical facility. Declare any health issues at booking; the ship’s medical team appreciates advance notice and the good ones will reassure you thoroughly about what to expect. See Antarctica for every traveler for age, fitness, and accessibility considerations in detail.
