Surf Life Saving NSW is warning swimmers about dangerous surf conditions along the entire coast this weekend.
A south easterly swell is expected to reach 2 to 3 metres at its peak, with a swell period around 15-17 seconds.
These conditions will be hazardous for coastal activities such as swimming, surfing and rock fishing.
Conditions are expected to ease overnight on Saturday 19 April however the swells will stay around 1.5-2m on Sunday 20 April.
“With the onset of these dangerous condition we strongly encourage swimmers to follow all safety warnings and avoid entering the water unless there is an active patrol on duty, which will be signified by the red and yellow flags.
“If you are ever unsure about the conditions, have a chat to one of the lifesavers or lifeguards on duty before entering the water,” said Andy Kent.
At the beach, follow these simple safety tips:
* Always swim between the red and yellow flags
* Read the safety signs
* Ask a lifesaver/lifeguard for safety advice
* Learn how to identify a rip
* If you need help, stay calm and attract attention
* Always wear a lifejacket while rock-fishing
* If witnessing an in-water emergency call 000-Police
