The National Sea Rescue Institute (NSRI) is urging beachgoers, anglers and coastal hikers to exercise extra caution as strong spring tides are expected along South Africa’s coastline over the Heritage Day long weekend and school holidays.
The NSRI says the spring tide will begin on Saturday and continue for about four days, with the strongest tidal conditions expected through to Tuesday.
NSRI spokesperson Andrew Ingram says the full moon will reach its peak on Saturday night, contributing to some of the strongest tidal ranges of the year.
He says the timing of the spring tide, shortly after the equinox, could result in hazardous coastal conditions.
“This means stronger rip currents at beaches, fast tidal currents in estuary mouths like Knysna Heads, and waves reaching further up the rocks than usual,” Ingram says.
The NSRI is advising anglers fishing from rocks to wear life jackets and carry appropriate flotation equipment.
Coastal hikers are also being warned that some paths could become hazardous or be cut off completely during high tide.
The public is encouraged to check local tide times before heading to the coast and to remain alert to changing conditions.
The NSRI says swimmers should use lifeguard-protected beaches, remain between the designated flags and keep a close eye on children near the water.
The warnings come as the Heritage Day long weekend coincides with the school holidays, with thousands of South Africans expected to travel.
Motorists are also being urged to exercise caution, as traffic volumes are expected to increase on major routes and around popular holiday destinations.
