Monitoring water temperature during a dive is essential primarily to prevent hypothermia and ensure that divers have appropriate exposure protection. Water temperature impacts how quickly the body loses heat. In cold water, divers are at a greater risk of hypothermia, which can occur even in relatively mild temperatures if exposure is prolonged.

By keeping an eye on the water temperature, divers can determine the level of thermal protection needed, whether through wetsuits, drysuits, or other means. This allows them to acclimatize appropriately and select the right gear to maintain body warmth, which is crucial for safety and comfort during the dive.

Additionally, understanding water temperature contributes to overall dive planning, including knowing how long one can safely remain in the water. Maintaining proper thermal protection helps to ensure that divers remain physically capable of enjoying the dive and safely executing their planned activities.
