The National Sea Rescue Institute (NSRI) has issued a warning for beachgoers, anglers, and coastal hikers to exercise extra caution this weekend due to a full moon spring tide coinciding with the school holidays and Heritage Day long weekend. The full moon is set to occur on Saturday, September 26, at 18h48. According to the NSRI, the strongest spring tides are expected from Saturday, September 26, to Tuesday, September 29.
The spring tide is also occurring shortly after the September 23 equinox, when spring tides tend to be among the strongest of the year. An equinox is a moment when the sun sits directly above the equator, resulting in roughly equal day and night lengths everywhere on Earth. This alignment of the sun, moon, and Earth strengthens the pull on the ocean, leading to spring tides that can last for several days.
The NSRI has advised families heading to the coast to plan around the tides. They recommend checking tide times, swimming at lifeguard-protected beaches, and wearing a life jacket when fishing from rocks. Andrew Ingram, NSRI Communications Manager, emphasized the importance of taking precautions. He suggested that beachgoers should be aware of the tide times and take extra care on the outgoing tide, when rip currents are often at their strongest.
During a spring tide, higher high tides and lower low tides can be expected, resulting in a bigger tidal range. This can lead to stronger tidal flows, making rip currents stronger and putting swimmers at risk. Additionally, coastal paths and hiking trails may be cut off or become dangerous at high tide, and rock and shoreline fishing can become hazardous as waves can reach beyond areas that are usually safe.
To stay safe, beachgoers are advised to swim only at lifeguard-protected beaches and between the lifeguards' flags. They should also check the South African Weather Service forecast and local tide tables before heading out. Coastal hikers and anglers should plan routes around local high-tide times, avoid trails that may be cut off, and keep a safe distance from the water's edge.
The NSRI has also provided safety tips for boating and paddling. They recommend wearing a life jacket, carrying essential safety equipment, and keeping a cellphone charged and stored in a waterproof pouch. The free NSRI SafeTrx app allows users to log their trip and call for help quickly. Furthermore, the NSRI advises people to not drink alcohol before swimming, boating, or fishing, and to ensure a responsible adult is always watching children in and near the water.
In addition to the spring tide safety warnings, the NSRI has urged families to take extra care around beaches, swimming pools, rivers, and dams during the school holidays. This includes supervising children and learning how to respond in emergency situations. By taking these precautions, beachgoers, anglers, and hikers can minimize the risks associated with the strong spring tide and enjoy a safe and enjoyable Heritage Day weekend.
