Weather and seasons in Antarctica

Dramatic seasons, harsh temperatures and impressive winds all help make the South Pole one of the most interesting weather locations on Earth.

Weather and seasons in Antarctica

If you've never visited a polar destination, you're probably wondering what you can expect weather-wise when you travel to Antarctica. Even if you've spent time in the Arctic Circle, the Antarctic is an entirely different experience. The high elevation and large landmass makes the south pole significantly colder than the north. Of course, temperature is only one piece of the antarctic weather puzzle. Here's an overview of what weather conditions are like on Earth's southernmost destination:

Seasons in Antarctica

Antarctica only has two seasons: summer and winter. Because it's located in the southern hemisphere, Antarctica's summer is from October to February. During this time, the sun is almost always in the sky. Days rapidly get longer there in summer, until, eventually, the sun doesn't set at all. This phenomenon is called the Midnight Sun. Although there are multiple places in the northern hemisphere that experience this perpetual sunlight during half of the year, Antarctica is the only southern location where it can be seen.

January is the warmest month in Antarctica, during which average temperatures climb all the way up to 0 degrees in the Antarctic Peninsula. However, the average temperatures ranges from -10 degrees celcius to -60 degrees, depending on how far into the continent you travel.

If anyone is in Antarctica once winter comes, they're staying until summer returns. Flights and ships cease travel to and from Antarctica once the weather starts to turn, as conditions become too treacherous for travel. Typically, researchers are the only people who brave the antarctic night. This is a valuable time for astronomers, who can use the complete darkness to get spectacular views of the universe. Climatologists are also busy during this time of year tracking and comparing the temperatures on and below the continent's surface.

Late Summer Cruising in Antarctica: February - March

If you choose to go on an Antarctica cruise in February or March, you will be seeing the continent during its late summer period. This provides a variety of benefits, including the ability to explore more thoroughly as the ice melts and breaks apart, allowing for a high chance of seeing whales on the Peninsula.

What whales might you see?

Late summer is the best time to see whales in Antarctica. It is most common to see humpback whales, minke whales and killer whales, though it's possible to see many other species as well. These can include blue whales, fin whales, sei whales, southern right whales and sperm whales. 

What about penguins?

By March, those adorable penguin chicks are growing up. They begin to fledge and grow into their adult feathers, while their parents may already have gone out to sea to begin to prepare for their own molting season. 

Why go during this season?

If you're an explorer who wants to see as much of Antarctica as possible, choose a late-summer cruise. As the polar ice melts, you'll have access to points much farther south than you would during other travel seasons. You will certainly see some wildlife, as well, and will get to know the untouched majesty of Antarctica in this particular form.
