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 Africa/Lagos local. Folk tradition, not a scientific forecast.

Last spring tide on Wed 20 May (range 1.6m). Next neap on Mon 25 May.

Spring tides cluster around new and full moons (biggest swings). Neap tides land on quarter moons (smallest swings). See the spring tide and neap tide glossary entries for the why.

Brass is a coastal town at the western mouth of the Niger Delta, on the Brass River estuary where one of the Niger's major distributaries meets the Atlantic. It is the administrative headquarters of Brass Local Government Area in Bayelsa State and one of the oldest recorded trading settlements in the Niger Delta, with a documented history of contact with European traders from the late 15th century onward. The setting is estuarine delta in its most complete form: Brass sits on a tidal island formed by the Brass River to the east and a series of tidal creeks to the west. At high tide, the town is effectively surrounded by water; at low tide, mud flats extend around the island perimeter. The water is brown-black with the tannin load from the vast Niger Delta mangrove system upstream. The Atlantic approaches to Brass are shallow and shifting — the bar at the Brass River mouth requires careful navigation. Tide predictions for Brass use Open-Meteo Marine's global model. Timing accuracy ±45 minutes, height accuracy ±0.2 to 0.3 metres. The Niger Delta coast has semidiurnal tides with spring range of approximately 1.0 to 1.5 metres. The actual water level at Brass is also strongly influenced by the Niger River discharge: in the flood season (July to September), high freshwater outflow from the delta pushes water levels in the estuary significantly above the tidal prediction. At peak flood, the entire delta network operates at elevated baseline, and the tidal oscillation rides on a raised platform. For the Ijaw fishing communities that have inhabited Brass for centuries, the combination of tidal estuary, deep-water river mouth, and offshore Atlantic bank creates a multi-zone fishery. Bonga shad — the most important artisanal fish by volume in the Niger Delta — is caught by seine net in the estuary channels on the ebb tide. Larger grouper and snapper are taken on handlines at the river mouth bar, where the outgoing tidal current concentrates fish. Offshore trolling from the Brass bar produces kingfish and barracuda. The Brass area has petroleum industry infrastructure: the Agip (Eni) oil terminal at Brass is the export point for oil from the western Niger Delta's ENI-operated fields. The terminal is located several kilometres south of the town on a dedicated jetty. The industry presence defines the economic background of modern Brass but the artisanal fishing community predates the oil era by several centuries. Historically, Brass was a significant 19th-century trading state — the Nembe Kingdom — with direct trade relations with British merchants. A notable historical incident is the Akassa Raid of 1895, when Nembe warriors attacked the Royal Niger Company's trading depot at Akassa in response to a trade embargo; the confrontation illustrated the economic tensions between traditional trading communities and colonial monopoly companies. The story is documented in the local museum. Access to Brass is by speedboat from Yenagoa (Bayelsa State capital, 2 to 3 hours) or by road-and-boat combinations. There is no direct road to Brass from the mainland; water transport is the defining mode of access. The waterfront of Brass town faces the estuarine channel directly, with the town's jetty and beach strip extending along the riverfront. On any given morning, the bonga fleet's return provides the same visual sequence that has defined this waterfront for generations: the narrow wooden canoes, the nets stacked in the bow, the catch sorted by the landing crew. The bonga itself — Ethmalosa fimbriata, also called bonga shad — is one of the most important fish in West African food security terms. Its high oil content makes it ideal for smoking, and smoked bonga travels throughout the region as an affordable protein source. The creeks and waterways around Brass are navigable by small motor canoe through the mangrove system for 30 to 40 kilometres in multiple directions. The labyrinthine character of the Niger Delta — hundreds of channels, most unmarked, with tidal currents that change direction every 6 hours — makes local knowledge essential. Travelling into the creeks without a local guide familiar with the specific tidal channels and current patterns is a genuine navigation risk. Distances that appear short on a map can require hours of travel through convoluted creek routes. Bayelsa State, of which Brass is a coastal community, has the highest concentration of oil production infrastructure in Nigeria relative to its area. The environmental damage from decades of oil spills in the Niger Delta — documented by multiple UN and NGO reports — affects water quality and fishery health across the delta, including in the Brass River system. The fishing community's awareness of and response to this environmental context is an important part of understanding the contemporary economy and culture of Brass.
