About this spot
The Bay of Islands is Northland's hero waterway — 144 islands carved into a 16km-wide bay where Captain Cook first landed in 1769. Paihia and Russell sit at the centre, and from either launch you can foil to Roberton Island, Motuarohia, or duck into Te Pahi inlets when the westerly fills in. Mornings are typically glass-off until around 10am, when the predominant westerly trade builds 10-15 knots through the afternoon. Water temperatures sit at 21-22 C in February and rarely drop below 16 C in winter, making it the warmest reliably-ridable harbour on the North Island.
The geography is forgiving. Even when the open ocean is rough, you can almost always find a flat lee behind one of the larger islands — Urupukapuka and Moturoa both block the westerly swell. Beginners should stay in Veronica Channel between Paihia and Russell where there's no fetch, while more confident riders can run the 8km downwinder from Otehei Bay back to Paihia on a building afternoon breeze. The local eFoil school runs out of Paihia wharf and rents Lift, Fliteboard, and Takuma kits.
Regulatory-wise, Maritime NZ rules apply alongside the Northland Regional Council Navigation Safety Bylaw: the 5-knot rule is enforced within 200m of shore, within 50m of any other vessel or swimmer, and inside marked swim zones at Paihia, Russell, and Opua. The bay is a marine reserve in patches (Maunganui Bay rahui, Cape Brett) — eFoils are permitted but anchor zones and dolphin-watching boats deserve a wide berth, especially November-March when bottlenose pods are active.
