The Somosomo Strait, off Taveuni in Fiji, is defined by strong currents, dramatic wall topography and prolific reef life. The Great White Wall anchors the site mix, with drift dives threading through lava tubes and along vertical drop-offs. Shallower reef and pinnacle sites like Annie's Bommie and Cabbage Patch serve beginners, while The Corner and The Great White Wall itself demand advanced buoyancy and current management. Grey Reef Shark, Giant Moray and Chromodoris Nudibranch are among the consistently observed highlights across the strait.
Monthly water temperature across Somosomo Strait's sites, from satellite sea-surface data corrected for depth. The band shows the site-to-site spread.
Water stays warm throughout the year, with the coolest period running from August through October and peak warmth in April. The best-months data points to May through October as the most popular window, broadly aligning with calmer, drier conditions when visibility on the walls can be excellent. Currents run strong year-round, which is precisely what draws marine life to these sites, so divers should expect drift conditions regardless of season.

The strait hosts a wide range of observed species. Giant Moray and Chromodoris Nudibranch appear at the vast majority of sites, while Grey Reef Shark and Whitetip Reef Shark are regularly encountered on the walls and reef edges. Signature species include Zebra Shark, Napoleon Wrasse and Regal Angelfish, and the reefs are busy with Twoband Clownfish, Dot And Dash Butterflyfish and Swallowtail Angelfish.
All sites listed in the Somosomo Strait are boat-access only. Operators including Dolphin Bay Divers Retreat, Dive Academy Fiji, Viani Bay Resort and Sau Bay Resort and Spa Rainbow Reef run boat trips to the sites. There are no shore-entry dives recorded in this area.
The strait mixes wall, reef, pinnacle, cavern and drift site types. The Great White Wall is the signature experience, entered through a lava tube and dropping to significant depth along a white soft-coral wall. Sites like Yellow Tunnel add cavern topography, while Cabbage Patch is characterised by its distinctive cabbage coral formations. Shallower pinnacle sites such as Annie's Bommie offer a different pace for those wanting a less current-driven dive.
