How do currents affect wreck diving safety?

Strong currents can significantly impact wreck diving safety by introducing hazards at various stages of the dive, including approach, ascent, and exit. When divers approach a wreck in a strong current, they may struggle to maintain control and orientation, increasing the risk of accidents. During ascent, currents can make it difficult to return to the surface safely, potentially leading to delayed safety stops or even decompression sickness if divers are pulled away from their planned ascent route. Exiting the water can be equally challenging, as currents can push divers away from their exit point, making it hard to safely return to the boat or shore.

Understanding the influence of currents helps divers prepare adequately, which includes choosing appropriate entry and exit points, planning dive profiles considering the strength of the currents, and recognizing when conditions may be too dangerous for a dive. Proper planning and awareness of currents are crucial for ensuring a safe wreck diving experience.
