Indian Ocean is the third largest ocean of the world in terms of area. A very less part of it lies to the north of the equator. According to its shape, its expansion towards north is less and more in the south. On this basis, the currents of Indian Ocean are classified into North Indian Ocean Currents and South Indian Ocean Currents. 

Their description is as follows:

Currents of North Indian Ocean:

1. North – East Monsoon Drift: It is also called North – East Monsoon Runoff. This drift starts from Malacca Strait and enters the Arabian Sea flowing along the coast of the Bay of Bengal. 

2. Counter Equatorial Current: This current starts near Zanzibar Island in the west and flows eastward.

Currents of South Indian Ocean:

1. South Equatorial Current: This current flows from east to west in the south near the equator. 

2. Madagascar Warm Current: The branch of the South Equatorial Current flowing on the eastern coast of Madagascar Island is called Madagascar Current. 

3. Mozambiqe Warm Current: On reaching Madagascar Island, the South Equatorial Current divides into two branches. One of the branches flows towards the south along Madagascar Island and the other branch enters into Mozambiqe Channel.

4. Agulhas Warm Current: The Madagascar Current and the Mozambiqe Current in south along Madagascar Island merge and become united. This joint current is called Agulhas Current. 

5. West Winds Drift: This flows from west to east in the south of Indian Ocean and reaches near the southern tip of west coast of Australia. 

6. West Australian Cold Current: One branch of the West Winds Drift flows through the south of Australia and the other branch turns to the north from the western coast of Australia. This second branch is called the West Australian Cold Current.
