What defines cold water diving?

Cold water diving is characterized by diving in water temperatures that are typically below 10°C (50°F). This definition is important because diving in colder conditions requires specific training and equipment to ensure divers can maintain their body heat and manage the physiological effects of the cold water, such as hypothermia and reduced mobility.

In colder temperatures, divers often wear thicker wetsuits or drysuits to provide insulation, and they need to be aware of the increased risks associated with cold-water diving, such as impaired dexterity and the potential for more rapid depletion of body heat. Understanding the thermal dynamics of cold water is essential for safety and effective diving practices, making the correct identification of cold water diving crucial for divers planning their dives in various environmental conditions.
