Tidal range

In the Northern Mariana Islands, the mean tidal range is around 1 to 2 m.


The world's highest tidal range can be found in the Bay of Fundy in Canada, where it is up to 16 meters, and at spring tide even over 20 meters. The Bay of Fundy is located on the Atlantic 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 one and three meters. In the western Baltic Sea, on the other hand, the tidal range is only 0.3 meters, while it is barely noticeable in the eastern Baltic Sea.

Longitude and latitude

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

Δφ = from around 13 to around 20 north latitude

Δλ = at around 14 east longitude

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

Legal time

For the Northern Mariana 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) = + 9 h

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

High sun

For the sake of simplicity, we assume a north latitude of 15 to calculate the midday high sun on the islands.

If the sun or its image point is exactly at a latitude of 15 , the sun will be exactly perpendicular to the sky at noon. This happens exactly twice a year, roughly 58 days after March 21st and 58 before September 21st.

Mountains or elevations

The highest mountain in the country is an unnamed location on the island of Agrihan, with a height of 965 m.

Other high mountains are:

  • Mt. Tapotchau on Saipan, with a height of 474 m.
  • Mt Sabana is the highest mountain on Rota, with a height of 480 m.
  • Mt. Lasso on Tinian, with a height of 163 m.
  • Mt. Taipingot on Rota, with a height of 141 m.
  • Kastyu Hill is the highest mountain on Tinian, with a height of around 185 m.

There are four other smaller rivers on Rota.

There are no rivers on the other islands.
