CURRENTS The currents are complex and often strong, particularly in this vicinity where rates of up to 6 knots have been experienced. They are subject to large changes in speed and direction during the course of the year due to the seasonal reversals of the monsoon system of winds. Mariners are warned to watch for indications of abrupt changes in currents and to exercise due caution. Admiralty Sailing Directions should be consulted for further details.
