A period of unusual and powerful waves are predicted across the country on Tuesday, June 30. Although the waves may be hard to see, they could spell danger for members of the public.

“The South African Weather Service have predicted unusual wave periods for Tuesday, the 30th of June, which may result in relatively large powerful waves in between smaller waves. Because of this predicted unusual wave period, a quick glance at the sea during the lull in waves may not reveal the hidden danger of a larger wave that may suddenly break the pattern of the smaller waves,” said NSRI spokesperson Craig Lambinon in a statement.

“The concern is for anglers, beach-goers and coastal hikers who may be caught off guard by an irregularly large wave that could potentially sweep them off the rocks along the shoreline.”

On Tuesday, paddlers, boaters and surfers may also be caught off guard by a wave that is more powerful than the norm in the surfline along the coast.

According to the NSRI, these large waves may have the potential to damage some vulnerable coastal infrastructure.

TheĀ NSRI are appealing to boaters, paddlers, beachgoers, surfers, coastal hikers and anglers and the public to be cautious around the coastline and to follow SAWS forecasts. NSRI are appealing for caution and extra vigilance on Tuesday around the coast.
