Foveaux Strait M2 Tidal Component

Foveaux Strait M2 Tidal Component

This animation shows the chief tidal current in Foveaux Strait. Tidal currents on the west coast of Stewart Island are small, but around the northern and southern coasts of the island and in Bluff Harbour and Oreti Estuary there are strong tidal currents. Overall currents (not shown here) in Foveaux Strait however, are strongly wind-driven with the prevailing wind being from the west. The Southland current, which carries water from the subtropical convergence west of New Zealand, flows through Foveaux Strait.
