Climate of Antarctica

Antarctica is known worldwide for its icy temperatures and dry conditions. Because of its proximity to the icy Southern Ocean and relatively high altitude, Antarctica has a year-round polar climate. In fact, Antarctica has areas where the thermometer regularly drops below -50 degrees Celsius.

Climate averages for the whole year

  • Day: the average daily temperature during the day is between -53°C and -28°C
  • Night:the average nighttime temperature is between -57°C and -37°C
  • Rain: it rains 0 days and there is a total of approximately 12 mm rainfall
  • Snow: it snows an average of 12 days per year
  • Sun hours: throughout the year there are 99 sun hours
Maximum temperature: between -53°C and -28°C
Warmest month: -28°C in January
Coldest month: -53°C in June
Night temperature: between -57°C and -37°C
Dry days: 353 days
Days with rain: 0 days
Days with snow: 12 days
Total rain sum: 12 mm
Hours of sunshine: 99 hours

As a geographically isolated continent, Antarctica experiences some of the worst climatic conditions in the world. Because the continent is so far from the equator, it sees very little sun due to its latitude. Constantly low temperatures result from the continent's high altitude and lack of sunlight.

Seasonal temperature swings are a reality in Antarctica, despite the continent's image as a permanent ice sheet. Below is an overview of the continent's seasonal weather by time of year:

Spring (September-November)

Temperatures in Antarctica begin to slowly rise to -20 to -30 degrees Celsius across the continent in spring. There are more clouds and more rain showers in spring, as the polar front has begun its northward migration.

Spring in Antarctica is still quite dry, and most of the continent receives less than 100 mm of precipitation annually, despite the increase in clouds and rainfall.

Summer (December-February)

Some parts of Antarctica reach temperatures near 0 degrees Celsius throughout the summer. However, cold temperatures of -10 to -20 degrees Celsius persist around the continent's coastlines.

Although it is summer in Antarctica, the continent is still covered in snow because the absence of sunshine in winter prevents the ice from melting. Since this is the case, snow covers the ground all year round.

Autumn (March-May)

Temperatures in the autumn months of Antarctica hover around -20 degrees Celsius, making them quite close to spring temperatures. In autumn, the polar front begins its southern movement, resulting in cloudy skies and more rain than usual.

Although there are more clouds and rain in the fall, much of Antarctica still has a dry season, with annual rainfall of less than 100 millimeters.

Winter (June-August)

Extremely low temperatures of -40 to -50 degrees Celsius are common during the winter months in Antarctica. In winter, wind gusts can reach speeds of up to 200 mph.

Despite the icy temperatures, Antarctica experiences the least rainfall during the winter. The polar front, a band of clouds surrounding the continent, is weakest in winter, which explains this phenomenon. As a result, Antarctica receives very little precipitation in winter. Much of the continent receives less than 50 millimeters of rainfall each year.

Different regional climates

The Antarctic climate is very consistent across the continent, with the exception of the coastal areas, which are slightly warmer and wetter than the interior. Low summer temperatures of 10 to 20 degrees Celsius and low winter temperatures of 30 to 40 degrees Celsius characterize the coastal areas.

Differences in precipitation occur alongside temperature differences in Antarctica. Some coastal areas can receive up to 500 millimeters (mm) of precipitation annually, much more than inland areas.

In short, Antarctica has a severely cold and dry climate, with temperatures regularly dropping below -50 degrees Celsius. Nevertheless, the continent undergoes seasonal changes in temperature and precipitation.

Best time to visit Antarctica

Only a small number of daredevils visit the unusual and distant continent of Antarctica each year. If you're considering a trip to this frozen continent, you'll want to know when to go for the best experience. You'll find below the ideal time to visit Antarctica based on several variables, including weather, wildlife and accessibility.

Average Antarctic weather

All year round, Antarctica has cold, dry weather with typical highs and lows of -10 to -30 degrees Celsius. However, minima of -70 degrees Celsius have been recorded in winter in several regions of the continent. In terms of weather, the summer season, which lasts from November to March, is the ideal time to travel to Antarctica. The days are longer and the weather is slightly warmer during this period, with the sun rising around 6 a.m. and setting around 8 p.m.

Wild Animals

Penguins, seals and whales are just some of the unusual wildlife found in Antarctica. The breeding season, which lasts from November to February, is the ideal time to travel to Antarctica if you want to see these animals up close. Seals give birth during this time and penguins are busy reproducing and raising their young. In addition, several whale species migrate to the waters around Antarctica during this time to feed.

Only boats or planes can travel to Antarctica, and most tourists arrive there on cruises from South America or the Falkland Islands. Because the peak months are December and January, these cruises usually depart from November through March. It is best to book your cruise far in advance if you are considering visiting Antarctica, as they often sell out quickly.

The best time to visit by area

Although the summer months are often the ideal time to visit Antarctica, there are several exceptions depending on where you want to travel.

Ross Sea area

At the eastern edge of the continent, the Ross Sea area is known for its beautiful landscapes and diverse wildlife. The best months to visit this area are November through January, when days are longer and temperatures are a bit milder. Many different species of whales travel to the region around this season to feed.

Regional Peninsula

The Peninsula, located on the western half of the continent, is known for its rocky coastline and extensive penguin colonies. From November to February, when the penguins are actively breeding and raising their young, is the optimal time to explore this area. In addition, several species of seals give birth to their pups during this period.

Conclusion

The optimal time to travel to Antarctica depends mainly on your own interests and travel goals. The summer months from November to March are the best times to visit if you want to experience milder temperatures and longer days. Mating season, which runs from November to February, is the perfect time to come if you want to view the continent's unusual wildlife. Regardless of when you decide to travel there, Antarctica is a truly remarkable location that will undoubtedly offer an amazing encounter.
