The ocean is one big washing machine today, with strong onshore winds and swell coming from all over the place.

But things should improve as the weekend progresses.

The south-easters should swing to the south-west as the east coast low heads towards New Zealand, and the forecast is for west to south-westerlies by Sunday.

There should also be plenty of swell.
