CURRENTS
The currents are monsoonal in character. During the SW monsoon there is a branching, towards the NE, from the northern flank of the general SE´ly flow across the entrance to Gulf of Mannar. This continues as a N´ly flow through the narrow channels connecting the northern part of the Gulf with Palk Strait in December and January (NE monsoon) the flow is southward through these channels which implies a mainly SW´ly flow across the Gulf. For further information see also Sailing Directions, Admiralty Currents Atlases etc. The currents may on occasions, be markedly different from these average conditions and rates upto 2 kn may occur with prolonged strong winds.
