Wave starved east coast will finally see some larger swell

Angus McLean-Smith, Saturday August 18, 2018 - 14:25 AEST

The wave climate along the east coast of Australia has been on the tiny to small side of the scale in the last few weeks. However, thanks to a low pressure system expected to move into the southern part of the Tasman Sea, relief for surfers should arrive on Monday.

The southerly swell looks to peak on Monday, with Sydney expecting waves around three metres. Along the New South Wales coast, south swell magnets should see even larger waves. Waves on the south coast should be of a similar size, around three metres, however the peak of the swell should arrive earlier in the day. On the north coast slightly smaller waves are expected, generally between two and three metres, with a later peak in the swell.

This swell is due to strong southerly winds with a large fetch that are associated with a low pressure system moving eastward across southeastern Australia. As this system moves further east, winds looks to weaken leading to a declining swell from Tuesday.

You can't have swell without winds, on Monday most of the coast will see strong, predominantly southerly/southwesterly winds, weakening and becoming more southerly as the day goes on. Tuesday should see mainly westerly winds, weakest before lunch-time.
