Cape Town - The National Sea Rescue Institute (NSRI) has urged the public to be cautious around the coastline from Saturday until after next weekend - September 27 and 28 - as the full moon spring tide that peaks on Tuesday has begun to increase in intensity as it builds towards the peak.

Bathers, anglers, coastal hikers, and beach strollers were urged to be cautious and to heed the safety alert and be aware of the spring tide phenomenon, the NSRI said in a statement.

Bathers should only go to beaches where and when lifeguards were on duty and swim within the safe demarcated swimming zones that lifeguards posted, using their red and yellow flags.

The NSRI also urged parents to ensure that their children had responsible adult supervision around inland and coastal waters.

Spring tide occurs at the full moon and again at the new moon and brings with it a higher than normal high tide, a lower than normal low tide, and stronger than normal rip currents.
