Fig 1 shows the ocean currents off the coasts of Australia. Meridional (north-south) currents may have a large effect on coastal climates: southerly currents are usually relatively cool. There are obvious seasonal differences, but it is surprising that they are largest in the north of the continent, i.e. in the tropics.
Fig 1. Sea-surface currents (1), in terms of their speed and direction. The numbers by the arrows show velocities in km/day: 1 km/d equals 1.16 cm/s. The arrow thickness indicates the frequency of such a direction, according to the key in the top figure.
