In a statement released on June 20, the National Sea Rescue Institute (NSRI) and the emergency services appealed to bathers, boaters, paddlers, sailors, shoreline anglers, and coastal hikers to be cautious around the coastline as the full moon spring tide causes the daily two high tides to be higher than normal and the daily two low tides to be lower than normal.
NSRI spokesperson, Craig Lambinon, said the effect that spring tide has on the coast, caused by the gravitational effect that the moon has on the earth which causes the two daily high tides to be higher than normal and the two daily low tides to be lower than normal will already be noticeable around the coastline increasing in intensity towards the full moon peak, June 22, and then gradually declining in intensity towards the middle of next week.
He said the spring tides pose a potential hazard to bathers around the coastline, especially during the outgoing tide.
“With school vacation now in full swing we are appealing to coastal water users to be cautious during this full moon spring tide phase and the effect spring tide has around the coast,” said Lambinon.
“Be aware of coastal hiking trails that can be cut off during high tide.”
Lambinon said rough seas, brought on by winter storms and cold fronts, may contribute to hazardous conditions around the coastline during this spring tide phase.
“Inland water users are also urged to be cautious bathing, boating, and paddling on rivers, lakes, and dams where heavy rainfall is forecast for places,” said Lambinon.
He further advised people to follow the South African Weather Service (SAWS) daily forecasts and follow daily tide time tables around the coastline.
“Be aware of adverse weather, strong winds, fast-flowing rivers, and sea currents and drifts,” said Lambinon.
“Boaters, paddlers, and sailors, we are appealing to you to wear life jackets when your craft is underway, carry safety equipment, and download and use the free NSRI SafeTrx smartphone app.”
“We appeal to parents to ensure your children have responsible adult supervision in and around water.
“To everyone, we are appealing to you to be cautious during the remainder of the school vacation. Let us keep each other safe.”
