This border, that is located at Latitude 66° 33′ South, marks the Antarctic Territory according to one of the definitions.
The Antarctic Circle experiences a period of 24 hours where the Sun is above the horizon during the summer solscice on 21st December. The reason for this phenomenon is that the axis of the earth is tilted by 23.5 degrees.
South of the Polar Circle at Detaille Island in Crystal Sound is the farthest south that we will probably reach at Latitude 66°52' South.

Antarctic Circle FAQ
Where is the Antarctic Circle Located?
The Antarctic Circle, which is also referred to as a polar circle, is one of the five latitude circles that are used to divide maps of Earth. An expedition cruise to the Antarctic Circle will take travelers south of the Equator to the 66°33′45.9″ coordinates. The Antarctic Circle is between the Southern Temperate Zone and the Antarctic. This polar circle crosses through Antarctica, the Southern Ocean and the Balleny Islands.
What is the Average Temperature and Weather of the Antarctic Circle?
Due to the range of the Antarctic Circle, the average weather conditions can vary greatly. However, most expedition cruises that go near the Antarctic Circle stop at Detaille Island. This area can be warmer than many travelers would imagine. For example, in October, the temperature usually ranges from -7 to 0 degrees Celsius (19.4 to 32 degrees Fahrenheit). Of course, the Antarctic Circle can also be extremely frigid, depending on the time of year.
How Big is the Antarctic Circle?
The Antarctic Circle is slowly moving southward. This movement changes its exact coordinates by approximately 15 meters (49 feet) every year. At the current time, the entire area beneath the Antarctic Circle takes up 20 million square km (7.7 million square miles), which accounts for 4 percent of the Earth’s total landmass.
Who Discovered the Antarctic Circle?
Although we do not know which individual determined the existence of this Polar Circle, history does tell us that James Cook was the first person to travel to the Antarctic Circle. Cook reportedly crossed the circle via boat in 1773 as part of his second voyage to discover new regions.
What Wildlife Can Be Seen in the Antarctic Circle?
The exact area of the Antarctic Circle that you visit will directly impact the type of wildlife that you might encounter. During a cruise to the Antarctic Circle, it is possible that you will see a variety of penguin species, along with whales, seals and seabirds.
What Are the Unique Features of an Antarctic Circle Cruise?
A cruise to the Antarctic Circle is definitely a unique experience, and you may see a variety of photo-worthy things. Examples include wildlife, glaciers and icebergs.
One of the most intriguing facts about the Antarctic Circle is the region’s 24 hours of daylight and nighttime that take place once a year. To explain, December is filled with a full 24 hours of daylight to mark the solstice, and the opposite event occurs in June.
