When selecting the final decompression stop depth, what is the primary consideration?

Choosing the final decompression stop depth is crucial for ensuring the safety and effectiveness of the dive. The primary consideration should be the environmental surface conditions at the site. These conditions can significantly impact the diver's safety during the ascent and decompression phases.

For example, adverse weather conditions, strong currents, or poor visibility can make it challenging for divers to navigate to the final decompression stop safely. Unfavorable surface conditions might also require a more conservative approach to decompression to mitigate risks associated with emergencies during ascent.

While factors such as dive site popularity, the diver's experience, and the time of year can play a role in planning a dive, they are secondary to the immediate and tangible risks posed by environmental conditions. Safe diving practices always prioritize the current status of the dive environment to ensure the diver can complete their ascent safely and follow required decompression procedures.
