The search is expected to continue on Monday for a man from Alice who was swept out to sea at Eastern Beach in East London.
NSRI spokesperson, Craig Lambinon, says despite an extensive search for the 24-year-old man on Sunday, no sign of him had been found.
Meanwhile, Lambinon says a Plettenberg Bay fisherman rushed to rescue two children who had been been knocked over by currents in the Keurbooms River.
He says a family had been trying to cross the river when the parents lost hold of their five year old boy and eight year old girl.
Lambinon says the fisherman had witnessed the incident and rushed to help, hauling the children out from under the water and bringing them to safety.
Earlier, Plett NSRI volunteers also rushed to assist a woman on a jet ski who had landed in trouble.
Lambinon says with the holiday season upon us people should take care around water.
“Sadly, rip currents are the greatest cause of drowning accidents around the South African coastline. Rip currents are a river of water flowing out to sea against the incoming waves and are caused when the waves reach the shoreline. Rip currents allow water to be dispersed back into the ocean,” he said.
Lambinon says the NSRI is urging the public to visit beaches where life-guards are on duty.
He also says people launching any kind of craft on to water to wear their life jackets at all times, carry safety equipment and inform a responsible person about the time of departure and anticipated time of return.
Lambinon says the people should also visit the NSRI website for more safety tips.
