Enjoy Austral Summer

During the summer months when expedition cruising takes place (November-March) the winds abate considerably and the weather is surprisingly comfortable, averaging between 20 and 50 degrees F. Summertime in Antarctica also means 18-24 hours of sunlight, which allows life to flourish for a brief summer period and allows for our extensive exploration by small ship cruise.

Avoid Antarctic Winter

Antarctica travel is not available in the winter, as temperatures near the South Pole range from -40 to -94 F and winds can reach up to 200 miles per hour. The lowest Antarctic temperature ever recorded is -129F, the coldest temperature ever recorded on Earth. Weather in Antarctica is a lesson in extremes. Antarctica is the world’s coldest, windiest and driest continent.

Ushuaia Weather

Ushuaia, Argentina, is one of the southernmost cities in the world with a maritime climate that is tempered by in the influence of coastal mountains and the ocean. The snow-free summer is October through May with average lows of 40 and average highs of 60 degrees F.  This is the best climate in Ushuaia for hiking and trekking. Winter sees colder weather with more snow.

November to Early December

During November to early December, late spring/early summer in Antarctica, colder temperatures prevail with more ice. Scenery is pristine, white and otherworldly with frequent giant iceberg and pack ice encounters. Courting season for penguins begins during this time, and seals become visible on ice flows. Elephant and fur seals establish breeding territories. Spring wildflowers are in bloom in the Falklands and South Georgia.

Mid-December & January

Mid-December and January (mid-Summer in Antarctica) are typically Antarctica’s warmest months. Days get longer with increased amounts of sunshine. Penguin chicks are abundant. Seal pups become visible on South Georgia & Falklands. Receding ice allows for more inland exploration.

February & Early March

During February and early March (late Summer in Antarctica), whale sightings are at their peak. More snow-free beaches allow for sightings of large penguin rookeries. Penguin chicks start to fledge. Receding ice allows ships to explore further south.
