Spring Tide and Coastal Safety Precautions

The National Sea Rescue Institute (NSRI) urges beachgoers to exercise caution during the full moon spring tide, which peaks on Thursday, 2 April 2026, as it will affect tidal conditions over the Easter weekend. 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.

The effects of this full moon spring tide will be felt over the long weekend and for the next few days. The NSRI is advising holidaymakers, beach visitors, rock and surf anglers, and those walking on coastal paths to be aware of the larger tidal variation typical of spring tides.

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 Spring Tide:

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

This natural phenomenon can present potential dangers:

• Rip Currents: Stronger tidal flows intensify rip currents at beaches, posing a risk to swimmers.
• Rip Tides: Stronger tidal flows of water, especially in places like the Knysna Heads.
• Coastal Hiking Hazards: Some hiking trails near the coast may become inaccessible or hazardous during high tide in the afternoon over the Easter weekend.
• Fishing Precautions: 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:

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 in the late afternoon and early evening.
• 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 in the late afternoon.
• 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, an empty 5L water container with a rope attached) to throw 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 lets you log your trip and quickly and easily call the NSRI for help.

General Water Safety

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

Additional Precautions

• Time your activities: Be cautious during tide changes, especially when high tide recedes to low tide for beach visitors (in the late afternoon) and on the incoming tide for rock anglers.
• Stay informed: 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.
