Gan's diving is defined by strong channel currents, dramatic wall topography, and an exceptional shark presence. Drift dives dominate the site mix, with outer reef walls and channel corners funnelling water to attract Tiger Shark, Whale Shark, and Grey Reef Shark consistently across the area. The sunken oil tanker British Loyalty adds a substantial wreck to the repertoire, rated for advanced divers. A handful of calmer, shallower reef sites suit beginners, while the majority of sites reward intermediate to advanced divers comfortable with current.
Monthly water temperature across Gan's sites, from satellite sea-surface data corrected for depth. The band shows the site-to-site spread.
Water temperature stays warm year-round with negligible variation between the coolest and warmest months, making thermal comfort a constant. The best-months data points strongly to January through April as the prime window, likely reflecting calmer seas and stronger visibility on the outer reefs. The remaining months see a dip in favourable conditions, though the sites remain diveable.

Across Gan's dive sites, January, February, March and April are most often reported as the best months to visit.
Tiger Shark, Whale Shark, and Grey Reef Shark are all observation-backed and rated very common across the sites in Gan. Whitetip Reef Shark and Bull Shark have also been recorded, though less frequently. The channel and outer reef sites, where currents concentrate prey, tend to offer the most reliable shark encounters.
Most sites are rated intermediate, driven by the drift conditions on outer reef walls and channel entrances. However, Marc's Dream and Maakandu Outside are both listed as beginner-friendly, offering sheltered or gentler conditions. Divers new to drift diving should work with one of the local operators to match sites to their current handling skills.
All sites in Gan are accessed by boat. There are no shore-entry sites in the data. Multiple operators are based in the area, including Addu Scuba Dive, Diverland Gan, and Maldives Technical Diving, so arranging guided boat dives is straightforward.
The British Loyalty is a sunken oil tanker resting on a sandy bottom, making it the only dedicated wreck site in the area and one of the few requiring advanced certification. It functions as an artificial reef and sits deeper than most of the surrounding reef dives. Penetration of the structure and its greater depth demand careful buoyancy and navigation skills.
