Kimbe is the provincial capital of West New Britain, on the north coast of West New Britain island 1,000 kilometres northwest of Port Moresby by sea. The town of roughly 20,000 people is surrounded by palm oil plantations — West New Britain is PNG's primary palm oil province — but the bay it faces, Kimbe Bay, is a world-class marine environment that has been systematically surveyed by marine biologists and documented as having the highest recorded coral and fish biodiversity of any bay in the Pacific. The survey data is precise: over 860 coral species (out of a global total of approximately 1,000 known coral species) and over 1,000 fish species have been recorded within Kimbe Bay. The concentration of species is explained by the bay's geographic position at the convergence of the Bismarck Sea and the Pacific Ocean circulation systems, its deep-water connectivity through the bay floor (which prevents thermal stratification and maintains oxygen levels), and its isolation from the commercial fishing pressure that has depleted comparable systems in the Philippines and Indonesia. The palm oil industry has not, to date, discharged significant pollutant loading into the bay — a situation that could change with expansion of processing infrastructure on the bay margin. The tidal range at Kimbe is 1.2–1.5 m on spring tides, mixed semidiurnal. The bay is semi-enclosed by the West New Britain coast on three sides, with the open Bismarck Sea to the north. Tidal current in the inner bay is moderate — 0.5–1.0 knots on spring tides near the offshore sea mounts and reef structures that are the primary dive sites. The sea mounts, rising from 200–400 m depth to within 5–15 m of the surface, are the defining feature of Kimbe Bay's dive environment: their isolated summits attract pelagic species — hammerhead sharks, mantas, ocean sunfish — that move up from deep water onto the shallow summits on the current. The dive sites cluster around the offshore sea mounts and the fringing reefs of the small islands in the bay. Kimbe Island (Garove Island is the largest island in the bay), Restorf Island, and the Witu Islands are the most frequently dived locations. Restorf Island's reef is consistently cited by dive operators as the bay's most diverse single site — a wall that drops from 3 m to beyond 50 m, covered in gorgonian sea fans 2–3 m across and clouds of anthias fish. Visibility at Restorf regularly exceeds 30 m on calm days; current over the wall is 0.5–1.5 knots on spring tides, sufficient to keep the gorgonians extended and the fish aggregations active. Hammerhead sharks aggregate on the Kimbe Bay sea mounts between November and March, when the thermocline deepens and nutrient-rich cool water upwells over the summits. The aggregations are most reliably encountered at the Patience Rock and Kimbe Island sea mount sites. The observation window for hammerheads is typically the first 60 minutes of a dive, starting at dawn (06:00 entry), when the sharks are most active near the summit before descending to deeper water as the day warms. This timing aligns with the slack water before the flood tide, when current over the summit is minimal and divers can hold position on the shallow summit. For kayakers, the calm waters inside the bay on the eastern and southern margins — sheltered from the northwest monsoon by the bay's geometry — offer flat-water paddling with reef access. The inner bay mangroves south of Kimbe town are navigable by kayak on the upper half of the tidal cycle. Current in the inner bay is minimal on neap tides; spring tides increase the inner bay flow to 0.5–0.8 knots, which is manageable but noticeable on longer crossings. Anglers targeting the Kimbe Bay pelagic fishery find the bay's sea mounts and current lines productive for dogtooth tuna, wahoo, and giant trevally throughout the year. Black marlin pass through the outer bay on the June–October migration. The inner bay reef system produces consistent catches of snapper, coral trout, and grouper from the fringing reefs around the bay's offshore islands. Walindi Plantation Resort (established 1983) on the south side of the bay is the sole dedicated dive base. Its boats access all main bay sites; liveaboard trips reach the more distant Witu Islands. Accommodation in Kimbe town is basic — the resort is the primary infrastructure for marine-focused visitors. All tide predictions for Kimbe come from the Open-Meteo Marine gridded model. Timing accuracy is ±45 minutes; height accuracy is ±0.3 m above Chart Datum.
