What is the recommended surface interval between dives?

The recommended surface interval between dives is crucial for allowing the body to eliminate excess nitrogen absorbed during the first dive, thereby reducing the risk of decompression sickness (DCS). A surface interval of 2 hours and 38 minutes is both practical and within safety guidelines established by diving organizations. It gives the body adequate time to off-gas nitrogen and return to a normal state before making another descent.

Maintaining a proper surface interval not only enhances safety but also helps divers manage their dive profiles effectively, allowing for a more enjoyable experience without compromising their health. While various factors such as depth and time of the previous dive play into determining the exact necessary interval, 2:38 is a conservative and appropriate duration for most scenarios, particularly for recreational diving.
