Vigorous westerly winds, associated with a low pressure system over the southern Tasman Sea, are moving over south eastern and central eastern parts of NSW.
Winds will turn southerly on Saturday, August 19 and remain gusty along the coast as the low moves further east.
Interaction between a deep low pressure system near New Zealand ana a high pressure over southeastern Austraia with a ridge to the south will bring large seas along the New South Wales on Saturday.
Very heavy surf of around six metres which may lead to localised damage and coastal erosion is likely between Ulladulla and Port Macquarie during Saturday afternoon and evening.
Rock fishers, swimmers, surfers, and recreational boat users are being urged to exercise caution in the water this weekend as the forecast of hazardous conditions prompted surf lifesavers and the Bureau of Meteorology to issue a warning to beachgoers.
The warning extends over the entire coastline and is expected to be in place for at least the next 48 hours.
Offshore conditions are likely to be significantly stronger while southern facing beaches and exposed rock platforms are expected to bear the brunt of the weather.
At this stage it is anticipated that the hazardous swell conditions will continue well into Sunday before gradually easing into next week.
Rock fishers in particular are encouraged to wear a lifejacket and be aware of the swell period, especially as they get on and off exposed rock platforms.
With most of the state’s beaches remaining unpatrolled for another month, SLSNSW Lifesaving Manager Matt Du Plessis is urging the public to be aware of the changing conditions.
“It’s important that anyone looking to head to the beach this weekend is aware of these hazardous conditions and factors it into their planning.
“A great first port of call is the BeachSafe App or website which provides an overview of all patrolled beaches, beach closures and other important safety information which is particularly handy in winter,” said Mr Du Plessis.
“While we do have emergency assets on call, it does take time for them to get to you, so if you have any doubt about your abilities to handle the conditions it’s safer not to go out.”
