NSRI are urging the public to be extra cautious this weekend with the Full Moon Spring Tide that will cause stronger than normal rip currents around the coast.
Swimmers and shoreline anglers are most at risk and extreme caution is advised
Spring Tide happens twice every month, at full moon and at new moon.
Spring Tides bring a higher than normal high tide and a lower than normal low tide, causing stronger rip currents.
Rip Currents are caused when the water reaching the shoreline in waves, swells and sea currents needs to find a way to retreat back into the sea and this is achieved in rip currents (a river of water retreating through the incoming swells back out into the sea).
There are two types of rip currents, permanent rip currents, found alongside islands, rocky outcrops jutting into the sea, at river mouths, in between reefs and alongside harbour walls and piers, are found constantly occurring in the same place allowing the water reaching the shoreline to retreat back into the sea in the permanent rip current.
Temporary rip currents, found along beach fronts (along the shoreline), are forever changing their position and are unpredictable and can form suddenly along a beach front without warning at different places along the shore front throughout the day.
