Banks Peninsula M2 Tidal Component
The tidal current shown here is the main component of currents around Banks Peninsula.
Peak tidal currents in and out of Lyttelton and Akaroa Harbours are in phase with each other but out of phase with the maximum tidal currents around the peninsula. The total circulation (not shown here) also contains significant wind-driven currents from offshore winds. At times the Southland current may form an eddy behind Banks Peninsula in Pegasus Bay.
