How Warm Does It Get in Antarctica?

Antarctica is not associated with balmy weather, but a few instances of pleasant temperatures on the continent have been recorded since the middle of the 20th century. On 5 January 1974, a record high of 59° Fahrenheit (15° Celsius) was confirmed at Vanda Station. The record low in Antarctica also is the coldest recorded temperature of anywhere on Earth. On 21 July 1983, the temperature in Vostok, Antarctica, was logged as minus-128.5° Fahrenheit (minus-88.3° Celsius).

More facts about weather in Antarctica:

• Dry air is the norm in Antarctica. The little water vapor that might develop when temperatures increase above freezing is quickly turned to frost as the temperatures drop again.


• In rare situations, small amounts of water vapor in the air might remain suspended as ice crystals. When sunlight reflects off the crystals, it can create a wide array of visual displays.


• The Drake Passage is a narrow stretch of ocean between the southernmost tip of South America and the northern tip of Antarctica. Navigating this passage is extremely dangerous because of strong winds and currents. The English name for the passage is in honor of Sir Francis Drake, a 16th-century English explorer. In many Latin American nations, the passage is known as the Mar de Hoces, after Spanish navigator Francisco de Hoces, who is believed to have viewed the passage a half-century before Drake.

Frequently Asked Questions

What is the highest temperature ever recorded in Antarctica?

The highest temperature in Antarctica was recorded at the Argentine research base Esperanza on the northern tip of the Antarctic Peninsula, reaching a balmy 18.3°C (64.9°F) on February 6, 2020. This record-breaking warmth indicates a trend of rising temperatures in the region, which scientists attribute to climate change.

How does the summer temperature in Antarctica compare to winter temperatures?

Antarctic summers are relatively mild with coastal temperatures averaging around 0°C (32°F), while the interior remains colder. In contrast, winter temperatures can plummet to -60°C (-76°F) or lower, especially in the interior. The coast is somewhat warmer in winter but still experiences severe cold, often dropping below -20°C (-4°F).

Does the temperature in Antarctica vary by region?

Yes, temperatures in Antarctica vary significantly by region. The Antarctic Peninsula, which extends towards South America, experiences the mildest climate with temperatures occasionally rising above 0°C (32°F) in summer. The East Antarctic Plateau, conversely, is home to the coldest temperatures on Earth, due to its higher elevation and distance from the moderating influence of the ocean.

Are there any animals that thrive in the warmest parts of Antarctica?

While 'warm' is relative in Antarctica, some species are well-adapted to its milder regions. Antarctic krill flourish in the Southern Ocean, supporting a diverse food web. Penguins, seals, and seabirds also thrive along the coast, particularly where temperatures are less extreme, such as the Antarctic Peninsula.

How is climate change affecting temperatures in Antarctica?

Climate change is having a profound impact on Antarctic temperatures, particularly on the Antarctic Peninsula, where warming has been most pronounced. According to research, the region has warmed by nearly 3°C over the last 50 years, leading to retreating glaciers, reduced sea ice, and changes in wildlife populations and behavior.

What implications do rising temperatures in Antarctica have for global sea levels?

Rising temperatures in Antarctica have significant implications for global sea levels. As the continent's ice sheets, particularly the West Antarctic Ice Sheet, melt at an accelerated pace, they contribute to sea-level rise. Scientists estimate that if the West Antarctic Ice Sheet were to collapse completely, it could raise global sea levels by several meters, with catastrophic consequences for coastal communities worldwide.
