Oahu Dive Sites
Our goal at Deep Ecology is to provide our divers and student divers with top notch dive sites during the best conditions. We are constantly reviewing the conditions to provide an extraordinary experience.

Our six passenger propane fueled boat takes divers to the best possible sites depending on what the conditions are. We are at the whim of the ocean, so schedules are fluid based on what the ocean is doing.

Generally speaking, we dive the North Shore from May through September and the West, South and South East shores during the winter months. The North Shore is the only seasonal diving locale; when the big waves arrive, we dive in calmer waters.
