Port Master, Hakaumotu Fakapelea who is an experienced sailor and familiar with the seas in Tonga says the south Sub-tropical current lies parralel to Tongatapu and runs to Samoa across Ha’apai and Vava’u and is the strongest current in our waters.
According to Port Master Hakaumotu Fakapelea the Current travels at a speed of half to 1 knot per hour between Ha’apai and Tongatapu and could be stronger during high winds at sea.
The current Fakapelea said is at most times in harmony with Tonga’s trade wind direction which blows from south east.
