What should divers do in case of a sandstorm or rough surface current?

In the event of a sandstorm or rough surface current, staying anchored or secure at the dive site is the most prudent course of action. This approach minimizes the risks associated with potentially dangerous conditions.

When surface currents are strong, attempting to swim against them can lead to exhaustion, increased air consumption, and a higher risk of panic or disorientation in conditions that are already challenging. Leaving the dive site can further expose divers to risks such as losing their way back or getting caught in dangerous conditions away from the security of the dive site.

By remaining anchored or secured, divers can wait for conditions to improve and maintain better control over their situation. It also allows for a better ability to manage ventilation and energy levels while avoiding unnecessary risks associated with moving through hazardous environments. This choice emphasizes safety and situational awareness, which are critical components of dive training and practice.
