Gizo tide times

Predictions: Open-Meteo Marine (MeteoFrance SMOC, 0.08° grid) — heights relative to MSL (not chart datum / LAT). Model-derived.

Model-derived from a global ocean grid. Useful indication; expect about ±45 minutes on average vs. a local harmonic gauge, individual stations vary widely. See /methodology for per-region detail. Not for navigation.

The angler tradition for major/minor fishing windows: major ≈3-hour windows around moon transit and opposition; minor ≈2-hour windows around moonrise and moonset. Times are Pacific/Guadalcanal local. Folk tradition, not a scientific forecast.

Gizo is the capital of Western Province, Solomon Islands, sitting on Ghizo Island in the New Georgia group of islands. The town is the regional hub for the Western Province's scattered island communities, serving as the administrative centre, main market, and transport junction for the region. It is also the dive base for one of the richest concentrations of WWII wrecks and undisturbed reef in the Western Pacific. The tidal regime at Gizo is mixed semidiurnal, with a spring range of approximately 1.0 to 1.5 metres. The channels between the islands of the New Georgia Group — Blackett Strait, Vella Gulf, Kula Gulf — have tidal currents of 1 to 3 knots at spring tides, driven by the exchange between the Solomon Sea and the Coral Sea through the island passages. Dive operators in Gizo plan their reef and wreck dives around these currents; the walls of the channels have some of the best current-fed coral communities in the Solomons, and timing the dive to the current is essential for the soft coral and sea fan communities that depend on sustained water flow. The WWII history of Western Province is centred on Blackett Strait, the narrow passage between Kolombangara and New Georgia Island. In August 1943, the Japanese destroyer Amagiri rammed and sank the American PT-109, commanded by Lieutenant John F. Kennedy (later the 35th US President). Kennedy led the surviving crew through several days of open-water swimming and island-hopping before a coastwatcher network organised rescue. Kennedy Island (Plum Pudding Island) — where the crew sheltered for the first night — has a memorial marker and is visited by boat tour from Gizo. The PT-109 wreck itself has not been conclusively located. Diving around Gizo targets a combination of reef, reef wall, and WWII wreck sites. The Toa Maru, a Japanese freighter sunk in 1942 in 40 metres, is considered one of the best wreck dives in the Solomons. The Hellcat wreck (a WWII Grumman F6F fighter aircraft) lies in 30 metres near Gizo Harbour. Uepi Island Resort in Marovo Lagoon, southeast of Gizo, is the operational base for divers targeting the outer lagoon wall and Marovo passage dives. For non-divers, the Gizo market on the waterfront has a daily fish and vegetable market where Solomon Island produce — betelnuts, sweet potato, taro, and fresh reef fish — is traded. The market fish supply reflects the tidal rhythm: local fishers arrive by dugout canoe on the morning falling tide, having worked the reef overnight with lamps and hand lines. Snorkelling directly from Gizo Harbour is possible at high water when the harbour water is clearest. The inner harbour is shallow (2 to 5 metres) with moderate coral and fish presence. The outer passage walls, reached by boat in 10 minutes, have significantly better coral and fish density. Predictions on this page come from Open-Meteo Marine, a gridded global ocean model. Accuracy is typically within plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height — model-derived, not from a local gauge. The local tide authority is the Solomon Islands Meteorological Service.
