What aspect of dive conditions should divers assess before each dive?

Assessing the entire environmental and safety conditions before each dive is crucial for ensuring the safety and enjoyment of the dive experience. This comprehensive assessment includes factors like water temperature, visibility, current strength, wave conditions, and the presence of marine life, as well as potential hazards like boat traffic or underwater obstacles.

Evaluating all these factors allows divers to make informed decisions about their dive plans, such as adjusting their routes, choosing appropriate dive gear, and determining whether the dive can proceed safely. Focusing solely on one aspect, such as visibility, temperature, or the number of other divers, could lead to overlooking critical safety information that could impact the dive. Therefore, a thorough assessment helps divers prepare for varying conditions, ensuring a safer and more enjoyable diving experience.
