Extreme tidal conditions are expected at local beaches over the long weekend, considering the full moon spring tide.  

The National Sea Rescue Institute (NSRI) advised that higher high tides, lower low tides and strong rip currents can be expected for the next few days. Conditions will peak on Thursday, 2 April. 

“This natural phenomenon occurs when the sun, moon, and Earth align during the full moon phase, amplifying the gravitational pull on the Earth’s oceans,” said the NSRI in a statement.  

The NSRI warns of the effects of the spring tide and urges beachgoers, anglers and hikers to be vigilant.  

“Water levels will rise significantly, reaching further up the shoreline; more of the seabed will be exposed as water levels dip below average; the difference between high and low tide levels will be at its maximum.” 

The NSRI said these conditions will result in stronger-than-usual currents posing risks in certain areas, especially areas like the Knysna Heads.  

NSRI Communications Manager Andrew Ingram encourages beachgoers to swim at lifeguard-protected beaches and remain between designated flags, while advising anglers to keep a safe distance from the water and to wear flotation gear when fishing from rocks or cliffs. 

“Follow tide timetables, stay informed with local weather updates from the South African Weather Service and always prioritise safety. For emergencies, dial 112,” said Ingram.  

The NSRI also cautioned against alcohol consumption before taking part in water activities and urged close supervision of children near the water.
