THE National Sea Rescue Institute (NSRI) has urged beachgoers to exercise caution during this full moon spring tide, which peaked from December 4.

According to the NSRI, this natural phenomenon occurs when the sun, moon, and Earth align during the full moon phase, amplifying the gravitational pull on Earth’s oceans.

What to expect during a spring tide 

• Higher high tides: Water levels will rise significantly, reaching further up the shoreline.
• Lower low tides: More of the seabed will be exposed as water levels dip below average.
• Increased tidal range: The difference between high and low tide levels will be at its maximum.

Impacts and hazards of a full moon spring tide 

Spring tides often result in stronger tidal currents, particularly in narrow inlets.

This natural phenomenon can present potential dangers

1. Stronger tidal flows intensify rip currents, posing a risk to swimmers.
2. Some hiking trails near the coast may become inaccessible or hazardous during high tide.
3. Shoreline anglers should exercise extra caution, as higher waves may reach beyond usual safe zones.

Safety measures to follow 

To ensure your safety while enjoying coastal activities, the NSRI recommends the following precautions:

• 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

• Plan your hikes carefully, avoiding trails that may be cut off during high tide.
• 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 5L water container with a rope attached) that can be thrown to someone in the water.
• 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

• Drinking alcohol before doing an activity in or near water may put your life at risk.
• Ensure children are under the supervision of a responsible adult in and near the water.
• Be cautious around rivers, lakes, and dams, especially during heavy rainfall.
• Monitor adverse weather conditions such as strong winds and fast-flowing rivers.

Additional precautions

• Be cautious during tide changes, especially when high tide recedes to low tide for beach visitors and on the incoming tide for rock anglers.
• Follow local safety alerts and warnings issued by authorities.

Enjoy coastal activities responsibly
The effects of spring tides can last several days. By adhering to these safety measures, you can minimise risks and enjoy the ocean’s natural beauty responsibly.

The NSRI remains committed to safeguarding lives and promoting awareness of coastal hazards.
