What are the swimming risks in Da Nang, and what should you do if a current carries you offshore?

An eyewitness described a designated swimming area marked with flags and buoys, with at least two lifeguards on duty.

According to the eyewitness, a current carried a swimmer offshore and sideways despite his attempts to fight it. The lifeguard was slow to respond; the swimmer escaped the current after drifting sideways, and another swimmer nearby helped keep him afloat.

The eyewitness recommended swimming parallel to the shore without sudden movements and avoiding panic if carried offshore. They emphasized that being carried away from shore does not, by itself, mean the current is pulling you underwater.
