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 and the second city of the Solomon Islands, a compact town built on a small island in the Gizo Harbour and accessible by light aircraft from Honiara (45 minutes) or by the irregular inter-island ship service. The market, the main street, the waterfront, and the entire commercial district sit within 300 m of each other on an island barely 600 m wide; the town floods to ankle depth at the highest spring tides on the lowest-lying sections of the waterfront road. The WWII history in the Gizo area is concrete and documented. The Japanese destroyer Toa Maru sank in Gizo Harbour in 1943 and now rests at 48 m, intact and sitting upright, one of the most photographed wrecks in the Solomon Islands. A B-17 Flying Fortress bomber lies in 40 m to the west of the island, upright with the cockpit and engines accessible, its identity confirmed through wartime records. Kennedy Island — the uninhabited coral island 5 km northeast of Gizo — is where PT-109, Lieutenant John F. Kennedy's patrol torpedo boat, was sliced in half by the Japanese destroyer Amagiri on 2 August 1943. Kennedy and his surviving crew swam to Kennedy Island and were rescued after six days; the island's coconut grove is largely unchanged from the wartime photographs. The reef system around Gizo sits in the Coral Triangle — the species-rich zone between Indonesia, PNG, and the Philippines — and the fish and coral diversity close to the town is high even accounting for the proximity to human settlement. Reef shark species (whitetip, blacktip, grey reef) are common on the outer reef slope; bumphead parrotfish appear on the morning reef flat. The inter-island channels between Gizo, New Georgia, and Kolombangara produce tidal currents of 0.5 to 1.5 knots that concentrate fish life on the downstream side of reef structures. The Pacific tidal regime at Gizo is semidiurnal, spring range 0.8 to 1.2 m. The low-lying town is at some flood risk on the highest spring highs, particularly when combined with southeast wind setup from the open ocean — residents know the highest tide dates and position belongings accordingly. Anglers working the Kennedy Island passage channel catch wahoo, Spanish mackerel, and barracuda on the tide turns; the current concentration around the island's reef edge is the productive zone. The Gizo market on the main waterfront is a morning social event regardless of tide state, selling produce from the islands around the province. Predictions on this page come from Open-Meteo Marine (gridded model, ±45 min / ±0.2–0.3 m). The best documentary context for the Kennedy Island PT-109 story is the original account in The New Yorker by John Hersey (1944), based on Kennedy's own narrative. The island's coconut palm grove is largely unchanged from the wartime photographs; the memorial stone placed by the Kennedy family in 1985 is on the south beach. The Gizo dive operators run PT-109 history tours combining the Kennedy Island visit with a look at the Toa Maru wreck on the same morning. The wreck of USS Kennedy's destroyer, HMNZS Moa, and most notably the Kennedy Island PT-109 history site are all accessible from Gizo. The crossing from Gizo to Kennedy Island (Kasolo) by kayak takes approximately 20 minutes and is best timed for slack water or a favourable flood current in the channel; the channel shoals at low water and can generate confused surface chop if ebb current meets afternoon sea breeze. Gizo market mornings are driven by the fishing fleet's arrival, which typically tracks the early flood. Snorkelling around Gizo Island's offshore rocks is best in the morning before the southeast trade wind builds surface chop; tidal state affects clarity, with incoming tide bringing cleaner water from the ocean side. The Tetepare Island wilderness reserve, accessible by boat from Gizo, has fringing reef access governed by tidal state; the shallow reef passes into the Tetepare lagoon are only navigable within 1.5 hours of high water.
