Why should divers be aware of underwater currents?

Divers should be aware of underwater currents because these currents can significantly affect navigation and contribute to increased fatigue during a dive. Understanding the behavior of currents in a dive site enables divers to plan their route effectively, ensuring they can maintain control and safely return to their exit point. If a diver is caught in a strong current without proper awareness, they may find themselves drifting off course, which can lead to challenges in returning to the dive boat or shore. Additionally, fighting against a current requires more physical exertion, leading to quicker exhaustion and increased air consumption, posing safety risks. Awareness and knowledge of currents are therefore essential components of safe and enjoyable diving practices.
