Area and national borders

The Cook Islands cover a total land area of 240 km².

The islands, on the other hand, are spread over an area of water totaling around 2.3 million km². The Cook Islands can be divided into a southern and a northern group. The northern group includes:

  • Suwarrow

    With an area of 0.4 km², Suwarrow is the southernmost of the northern group and a pure atoll. This atoll has one of the best natural harbors in the entire Pacific. The first documented discovery of the island happened on September 17, 1814, when the crew of the Russian ship "Suvorov" landed here. The wife of the author of the novel "Treasure Island", Robert Louis Stevenson, is said to have exclaimed when she saw the atoll: "This is the most romantic island in the world!" Stevenson, who was born in Edinburgh on November 13, 1850, died on December 3, 1894 near Apia, today's Samoa.

  • Tongareva

    Tongareva has an area of 10 km² and is a flat atoll, which is hardly developed for tourism. It is an impressive example of a South Seas atoll. Located approximately 1,365 km north-northeast of Roratonga, it is the largest atoll in the Cook Islands. There are three entrances to the lagoon for ships (sailors), namely in the northeast and northwest. On August 8, 1788, Captain William Cropton Lever landed here with the "Lady Penrhyn" as the first European. Hence the other name of the island: "Penrhyn".

National borders

Due to their island location, the Cook Islands have no national border with any other country.


The Cook Islands have a total coastline of 120 km.

Tidal range in Avarua on Rarotonga

In Avarua on Rarotonda, the mean tidal range is around 2.5 m.


The world's highest tidal range can be found in the Bay of Fundy in Canada, where it is up to 16 m, and at spring tide even over 20 m. The Bay of Fundy is located on the Atlantic Ocean between the Canadian provinces of New Brunswick and Nova Scotia, which is called "Nova Scotia" in German and whose capital is Halifax.

On the German North Sea coast it varies between 1 m and 3 m. In the western Baltic Sea, on the other hand, the tidal range is only 0.3 m, while it is barely noticeable in the eastern Baltic Sea.

Longitude and latitude

The Cook Islands extend over the following geographical latitude (abbreviation Δφ) and geographical longitude (abbreviation Δλ):

Δφ = from around 8 S to around 23 S

Δλ = from around 156 W to around 167 W

You can find detailed information on this subject under: Geographical longitude and latitude.

Legal time

On the Cook Islands, the following value applies to Central European Time (CET), i.e. the time without summer time. A minus sign means that it is earlier there, a plus sign that it is later than CET:

Δt (CET) = - 11 h

More detailed explanations of the time can be found under: Time zones, time.

The highest point of the sun in Avarua

Avarua on the island of Rarotonga is located at a southern latitude of around φ = 21 , i.e. in the tropics. If the declination of the sun has a value of 21 , the sun is vertically above the city. This is about 10 days before December 21st and then again 10 days after December 21st. (see position of the sun).


Please note that the sun moves from east to north to west almost all year round. For example, on December 21st, the sun will be in the south at noon, as its declination of 23.5 S will be more southerly than the latitude of 21 S.


The highest point in the country is the Te Manga on the island of Rarotonga with a height of 652 m.

rivers and lakes

Due to the size of the individual islands, there are neither rivers nor lakes to speak of on the Cook Islands.

Pacific Ocean

The Cook Islands border the Pacific Ocean with a total coastline of 120 km - more precisely, the Cook Islands are located in the South Pacific, the so-called South Sea. This region of the Pacific Ocean includes the Polynesian Islands as well as parts of Melanesia and Micronesia.
