🇬🇺 Guam

Guam is an island territory in the North Pacific, where most scuba diving happens in the surrounding seas, with access to coral reef habitats and coastal drop-offs. Water temperatures are generally warm, and visibility can be good around reef edges, though conditions vary with currents and weather. Divers commonly find a mix of reef-associated fish, sandy slopes, and wall-like profiles, plus the occasional historic wreck in the wider region, depending on local operators’ site choices. Because Guam is small, dive options are more limited than in the broader Micronesian area, so many travelers focus on a short, guided trip with a local dive center and plan dives around tides and current flow.
