Quick answer: The only time to visit Antarctica is the austral summer, roughly late October to March — the season when expedition cruises operate. Outside those months the continent is locked in darkness and sea ice, and no voyages run. The “best” month within the season depends on what you want to see: November for pristine snow and penguin courtship, December–January for the warmest weather, long days, and penguin chicks, and February–March for the best whale watching. Browse our Antarctica cruises for ideas.
Is it a good time to visit right now? Only if it is the southern summer. Antarctic voyages sail from Ushuaia (and occasionally other gateways) between about November and March; from April to September there are no trips at all. So unlike anywhere else in this guide, the question is less “what is the weather like” and more “is the season open” — and which wildlife you most want to see.
The season is short and changes fast. Here is what each part of it offers:
| Month | Season Phase | Wildlife & Conditions | Best For |
|---|---|---|---|
| October | Season opening | South Georgia king-penguin courtship; heavy pack ice further south | South Georgia & the Falklands |
| November | Early season | Pristine snow, dramatic pack ice, penguins courting & nest-building | Untouched landscapes, photography |
| December | Peak season | Warmest; up to 20+ hours of daylight; first penguin chicks | Long days, mild weather |
| January | Peak season | Warmest; penguin chicks hatching; busiest departures | ★ Penguin chicks, best weather |
| February | Late season | Whales arrive, chicks growing, receding ice opens routes further south | ★ Whale watching, fur seals |
| March | Season closing | Best whale numbers, dramatic light, fewest ships | ★ Whales, quieter voyages |
| April–September | Closed | 24-hour darkness, sea ice, extreme cold — no voyages | (no trips) |
★ = late-season months are best for whales. See our full Antarctica weather guide for more detail.

“The Antarctica tourist cruise season is from October to March - but the best time to visit Antarctica is in December and January when the ice has broken down and ships can go further. My personal opinion is that you should try and book a cruise with an itinerary that crosses the Polar Circle to get the full Antarctica experience. For those cruises, you'll need to plan your trip from January to February. If you're looking for the best deal, the beginning and the end of the season may have lower prices. Antarctica tourism is growing rapidly, so the best time to go is now before it gets too crowded!”

In late October, cruises start to operate and travelers have the opportunity to be the first explorers of the Antarctic tourist season. Also during this time, guests to the southernmost continent have a chance to see the penguins of South Georgia and the Falkland Islands as it is the beginning of the mating season.
Late October and November is a beautiful time to visit Antarctica as the winter ice starts to break up and guests can venture into areas that were inaccessible earlier in the year. Also during this time grand ice sculptures and icebergs are visible, and wildflowers are in bloom in South Georgia and the Falkland Islands.
Note: In November it’s rarer to see baby animals in Antarctica because it’s too cold for seal pups and penguins.
Antarctica’s weather in the Spring results in increased temperatures, though it never gets quite “warm” in the southernmost continent. In September, temperatures rise from -7F to 0F and rarely fall below -20F. As October gets closer, temperatures rise to 14F and in November, temperatures rise from 14F to 28F.
The cruises begin their departures in late October. Aboard the ship, it is one of the best times to see the grand icebergs of the area. Travelers can also enjoy spotting penguins of South Georgia and the Falkland Islands as it is the start of the mating season.
Antarctica in the “summer season”, from December to January is the peak season for travel. During this time of the year, the days are very long and the temperatures are at their warmest (which is not saying much - it’s Antarctica!). For explorers interested in penguins, seals, and seabirds, visiting Antarctica from December to January is great as there is an abundance of active wildlife.
Travel tip: Pack some sunscreen if you’re traveling to Antarctica from December to January. The sunlight reflecting off the snowy, white terrain will expose travelers to a higher chance of sunburn.
Note: Keep in mind that travel to Antarctica in December and January is very busy as it coincides with Christmas and New Year. Be sure to book at least a year in advance if you’re looking to travel during this time.
Antarctica’s summer season is considered the “peak season,” as temperatures reach their highest during this time of the year. In December, the peninsula can reach 30F, South Georgia can reach 41F, and the Falkland Islands can get as warm as 46F. Once January hits, it is the height of summer in Antarctica. Travelers can enjoy consistent days of blue skies and sunshine, with the Peninsula reaching 32F and South Georgia reaching 43F.
During Antarctica’s summer season, travelers can do it all. The weather is ideal for visits to the Falkland and South Georgia islands. Guests also have the opportunity to sail across the Antarctica Circle as conditions at this time typically make this journey accessible. It’s also a great time to spot wildlife and go ice trekking. There are plenty of things to do during Antarctica’s summer season.
Visiting Antarctica in February and March is perfect for wildlife enthusiasts. The silver lining of the cooler temperatures is that whales can be seen more regularly. While on the cruise ship, try and spot the humpback and orca whales. It’s also during this time that travelers can see penguins hatch.
In February, warm(er) weather may occur leaving explorers plenty of opportunities to spot wildlife such as whales, and you have the chance to sail across the Antarctic Circle.
In March, Antarctica’s weather begins to cool. Guests can experience temperatures around 20 to 30F. It is possible during this time of year, the weather can be colder than the temperatures listed. It is also possible during this time that travelers can enjoy slightly warmer, sunnier days - nothing is certain in Antarctica!
March is really the last suitable month for travelers to experience Antarctica. From late February through March, whale watching is the top thing to do. Explorers have the greatest opportunity to spot killer and orca whales. March is also a great time to spot penguins hatching and to sail through the Antarctic Circle before the season to visit Antarctica comes to a close.
From April to September, you are unable to visit Antarctica because well, it’s absolutely freezing - in fact, below freezing (temperatures below zero!). From April to September, Antarctica begins to form “sea ice” which doubles its area and ships aren’t able to push through. In addition to the sea ice and below-freezing temperatures, during this time of the year, there are very strong winds and little to no daylight. These months of darkness are not suitable for any traveler, no matter how adventurous you are!
Antarctica’s weather from April to September is below freezing. Temperatures drop to lows of -20F / -29C. Cruise ships do not operate during this time due to the large amounts of sea ice that form.
There’s nothing to do in Antarctica at this time of year - because you can’t even get there!
Antarctica can only be visited in the austral summer, roughly November to March, when expedition cruises operate. The best month depends on your priority: November for pristine ice and penguin courtship, December–January for the warmest weather, longest days, and penguin chicks, and February–March for the best whale watching.
The Antarctic cruise season runs from about late October to March — the southern-hemisphere summer, and the only window when sea ice and daylight allow ships to sail. Most Antarctic Peninsula voyages depart between November and March; longer trips taking in South Georgia can start in October. There are no voyages between April and September.
Penguin chicks begin hatching in the rookeries around late December and January, which is also the warmest, brightest part of the season. Visit in December–January to see eggs and newly hatched chicks; by February and March the chicks are larger and beginning to fledge.
February and March are the best months for whales, when humpback and minke whales are most numerous in the food-rich summer waters and the receding ice lets ships travel further south. Late-season voyages also tend to be quieter, with fewer other ships at the landing sites.
December and January are the warmest and brightest months, with up to 20+ hours of daylight and temperatures on the Antarctic Peninsula often hovering around or just above freezing (roughly 32–41°F / 0–5°C at the coast). It is still cold and you need proper expedition gear, but these are the mildest conditions of the year.
No. From April to September Antarctica is in near-total darkness, wrapped in sea ice and battered by extreme cold and storms, and no tourist voyages operate. Tourism is limited entirely to the summer season of roughly November to March.
October and November are prime for South Georgia, when the vast king-penguin colonies are in full courtship and elephant seals crowd the beaches. South Georgia is visited on longer expedition voyages, often combined with the Falkland Islands and the Antarctic Peninsula.
A classic Antarctic Peninsula cruise runs about 10 to 12 days round-trip from Ushuaia, including two days each way crossing the Drake Passage — the famously changeable stretch of ocean between South America and Antarctica. Travelers short on time (or wary of the crossing) can choose a fly-cruise that flies over the Drake to join the ship. See our Antarctica cruises.
