Beachgoers are urged to beware of spring tides due to the new moon, which is expected to bring in higher and lower than usual tides, and stronger rip currents expected to last over the next few days.
According to Lifesaving South Africa, the stronger tides and currents were expected to start from this week.
While beach conditions were set to improve with offshore winds, there were other challenges, including blue bottles and sandblasting winds, that affected beachgoers, said Lifesaving South Africa.
The National Sea Rescue Institute (NSRI) has also issued a warning urging coastal communities and visitors to exercise caution during the new moon spring tide and said this phenomenon significantly impacted tidal conditions.
“This natural phenomenon occurs when the sun, moon, and Earth align during the new moon phase, amplifying the gravitational pull on Earth’s oceans. Higher high tides, where water levels will rise significantly, reaching further up the shoreline and lower low tides, where more of the seabed will be exposed as water levels dip below average, can be expected.
“There is also an increased tidal range and the difference between high and low tide levels will be at its maximum. Spring tides often result in stronger tidal currents, particularly in narrow inlets. This natural phenomenon can present potential dangers such as rip currents. Stronger tidal flows intensify rip currents, posing a risk to swimmers. Shoreline anglers should exercise extra caution, as higher waves may reach beyond usual safe zones,” said Andrew Ingram, communications manager for the NSRI.
Ingram said the effects of spring tides could last several days.
“By adhering to these safety measures, you can minimise risks and enjoy the natural beauty of the ocean responsibly. The NSRI remains committed to safeguarding lives and promoting awareness of coastal hazards. We urge people to stay safe, stay informed, and respect the power of nature,” he added.
Safety measures
To ensure safety while enjoying coastal activities, the NSRI recommends the following precautions:
Beach and swimming safety
– Swim at lifeguard-protected beaches: To avoid rip currents, swim between lifeguard flags.
– Be aware of rip currents: Rip currents are particularly strong during spring tides, especially during outgoing tides.
– Stay informed: Check daily weather forecasts from the South African Weather Service (SAWS) and consult tide timetables.
Coastal activities
– Hiking: Plan your hikes carefully, avoiding trails that may be cut off during high tide.
– Fishing: Shoreline anglers should maintain a safe distance from the water. When fishing from rocks or cliffs, they should wear a life jacket and carry flotation equipment (for example, a 2litre cool-drink container with a rope attached) that can be thrown to someone in the water.
– Boating and paddling: Always wear life jackets, carry essential safety equipment, and keep your cell phone fully charged in a waterproof pouch. The free NSRI SafeTrx smartphone app allows you to log your trip and call the NSRI for help quickly and easily.
General water safety
Alcohol and water do not mix: Drinking alcohol before doing an activity in or near water may put your life at risk.
– Supervise children: Ensure children have responsible adult supervision in and near the water.
– Inland water caution: Be cautious around rivers, lakes, and dams, especially during heavy rainfall.
– Weather awareness: Monitor adverse weather conditions such as strong winds and fast-flowing rivers.
