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/Auckland local. Folk tradition, not a scientific forecast.

Next spring tide on Thu 07 May (range 1.3m). Next neap on Wed 06 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.

Whakatāne sits at the eastern end of the Bay of Plenty, where the Whakatāne River meets the Pacific Ocean roughly 100 km east of Tauranga. The Bay of Plenty's open geometry produces a Pacific New Zealand semidiurnal tide with a noticeable diurnal inequality — two highs and two lows each day, but the two high waters differ in height by up to 0.3 m on some days. Mean spring range runs 1.5–2.0 m, measurably smaller than the Hauraki Gulf's compressed-funnel range. Low water drops to around 0.2 m above chart datum on a neap, and spring lows can push the water back to reveal tidal flats at the river mouth that are otherwise invisible. The most dramatic landmark visible from Whakatāne's waterfront is Whakaari, known in English as White Island. The island sits 48 km offshore and is New Zealand's most continuously active stratovolcano. On clear days the summit emits a visible steam and gas plume that marks the island even when cloud covers the sea horizon. In December 2019, an eruption during a tourist visit killed 22 people — the deadliest volcanic event in New Zealand since 1953. Tourist access to the island has been suspended since then and the regulatory framework for any future access remains under active review. The island does not disappear from the Bay of Plenty experience: it defines the seaward horizon from Muriwai Beach and from the Whakatāne Heads, and conditions on the water shift when wind swings around from the northeast sector where Whakaari sits. Five kilometres east of Whakatāne town, Ohope Spit extends across the mouth of Ohiwa Harbour and the outer coast faces northeast. The surf break at the Whakatāne Heads works off a long sand bar that builds up against the spit on northeast swell. It activates properly from around 1.5 m swell height and is best on a light southwest to offshore wind. Tidal state matters: the break tends to section badly at dead low water when the bar runs too shallow and too uniform. The middle two hours of the rising tide — roughly from 0.5 m to 1.2 m — hold the most shape. Check the tide table and add an hour: the sand bar runs about a kilometre from town, and paddling out against an ebbing current costs time. Northeast swell at this beach arrives from the same general direction as Whakaari, which gives the offshore view a rare framing of an active volcano behind a breaking wave. Ohiwa Harbour itself is a large sheltered estuary 10 km east of Whakatāne, with its own tidal range of around 1.5 m on springs. The harbour entrance is narrow — tidal flow through the entrance channel runs fast enough on the ebb to require attention from kayakers and small boat operators. Inside, the harbour opens into several square kilometres of intertidal mudflat and seagrass bed. Godwits — bar-tailed godwits, which migrate nonstop from Alaska — arrive at Ohiwa in late September and use the estuary intensively through summer before departing north in March. Oystercatchers and variable oystercatchers are resident year-round. At low water the mudflats extend 300–400 m from the mangrove fringe on the northern shore. Cockle gathering in the harbour is managed under a customary fishery framework — the local hapū hold harvesting rights and commercial collection is prohibited in the inner harbour. From the Whakatāne Heads rock platform, shore fishing for snapper and kahawai produces best results on the incoming tide. Snapper move onto the rock edges in around 3–5 m of water as the tide floods and hold there for roughly 90 minutes before the current becomes too strong to fish the bottom comfortably. The platform is accessible by a short track from the Ohope end of the spit. Kahawai tend to school in the wash zone closer to the surface — they can be taken on metal lures or flies in the surge gutters during the same flooding tidal window. Bring a decent set of rock shoes: the platform is kelp-covered near the water line. The best sessions tend to run from about 1.5 hours before high water until high water itself. Muriwai Beach (not to be confused with the gannet-colony beach near Auckland) faces the open Bay of Plenty north of Whakatāne. It is a flat, wide sweep of sand that holds family-friendly swimming at mid-tide when the shorebreak backs off. Rip patterns shift with the tide: at low water rips are more concentrated and visible, while at mid-flood they widen and slow. Swimming is safest from mid-rising to mid-ebbing tide on the upper beach section. Tide data for Whakatāne, Bay of Plenty comes from the Open-Meteo Marine API, a gridded model product.
