Experienced boardriders along the east coast of Australia have been, and still are, in for a treat. However, swimmers and inexperienced boardriders should take care, as conditions may become rough at times. An East Coast Low that formed off the NSW coast on Thursday has delivered some great waves over the past few days to much of the central and southern coasts of New South Wales. A southerly swell has combined with westerly winds to create these epic conditions. Offshore wave buoys were commonly recording significant wave heights of around four metres at Sydney and up to five metres down in Eden today. Northern coasts have not yet experienced the same size waves as southern coasts, with Coffs Harbour and Byron Bay only recording around two metres offshore. These great wave riding conditions will continue over the next few days with continued westerly winds and significant wave heights of around three to four metres expected in central and southern coasts of NSW until Thursday. The southerly waves will then continue further north into southern parts of Queensland, building waves to similar heights experienced in southern NSW. The slow movement, position and size of the low have generated these great waves. The low also combined with a high pressure ridge over inland NSW and QLD to create favourable winds to accompany the waves.
