The verdict comes from seven water factors and hard safety gates — not ten tabs. Go or stay.
Our own model
Our own forecast engine — not a third-party widget. It weighs these water factors into one go-or-stay verdict for this coast; the 0–10 dial is that verdict, read out as a number.
Safety gates
It all folds into a single 0–10 score and one verdict: go or stay.
A forecast, not a guarantee — the sea has the last word.

spearo.app folds wind, wave, swell period, visibility, tides, water temperature and risk into a single verdict — go to the spot or not. It computes 7 days ahead from open marine models (Open-Meteo, IPMA), with no sign-up and no accounts. Built for solo spearfishing off the rocks, where any mistake costs dearly.
Now live: 3016 spots across 406 stretches of coast — mainland Portugal, Madeira and the Azores.

The models set the window. Whether you go in is read only at the water: count the sets, watch the surge on the entry. If in doubt, you don't get in.

Open in the appSOLO is the biggest risk: underwater you can black out from lack of oxygen silently and fatally, with no one around. Solo is never truly «safe». Below are the best weather windows; carry a buoy, tell someone your plan and exit time, and any doubt — don't go.

Rules as of now — 25.10.2026 16:46 (Pacific/Auckland)
Spearfishing at Ahipara is a calm-window plan. The coast faces west, and any wind or swell from 210° round to 330° runs straight onto the reefs at the south end of Ninety Mile Beach. When a settled spell lands, the two free marks on this page, Shipwreck Bay Reef and the rocky Ahipara headland at Tauroa Point, hold snapper, butterfish and crayfish in the kelp. The forecast on this page gives the wind and swell call. Check the Fisheries New Zealand (MPI) rules before you go, including the dated Te Tauroa pāua closure.
Both marks sit on the exposed west coast. Their depths are single map readings that nobody has verified in the water, so treat them as a guide and confirm the exit from the beach.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Shipwreck Bay Reef | Boulder reef with kelp | about 5 m (unverified) | Calm-day dive; west swell shuts it | Verify a shore exit locally before you commit | At the south end of Ninety Mile Beach. Butterfish and cray hold in the kelp on settled west-swell days. |
| Tauroa Point (Reef Point) | Rocky headland | about 6 m (unverified) | Experienced divers, calm days only | Verify a shore exit locally before you commit | Cray holes and snapper on the Ahipara headland, open to big Tasman swell. It lies inside the Te Tauroa pāua closure band from 15 October 2026. |

Rules change and are regional. Before heading out, check with MPI (regional fishing rules / the NZ Fishing Rules app), DOC (marine reserves) and local notices (rāhui/mātaitai).
Ahipara is diveable only in settled spells, because big open-ocean west swell rules the diving here. The town faces west, at 270°, and wind or swell from 210° round to 330° blows straight onto the reefs. The visibility baseline we hold is about 8 m, and it is a provisional satellite estimate, not a reading from the water. Use the forecast on this page for the wind and swell window, then make the final call from the beach.
Snapper, butterfish and crayfish are the species named for this coast. The snapper rule for this west coast sub-area is a 27 cm minimum and a daily bag of 10. Butterfish have a 35 cm minimum. Spiny red rock lobster may not be taken with a spear, and the daily bag on this coast is 2. Spotted black groper is protected and may not be taken. All finfish together count towards a combined daily limit of 20 per person.
From 15 October 2026 to 14 October 2028 you must not take pāua (blackfoot or yellowfoot) within 2 km of the shore from Te Huahua / Iron Gate round Tauroa Point to Hunahuna Stream. Ask Fisheries New Zealand (MPI) and DOC about current closures before you get in.
The nearest towns with free marks on our map are Mangōnui, Matauri Bay, Paihia (Bay of Islands) and Russell, all in Northland. Each has its own page with its own wind sector and forecast, so plan from that page rather than borrowing the Ahipara window.
No. New Zealand needs no recreational sea licence. Check the MPI size and bag rules before you dive.
Check the Te Tauroa closure first. From 15 October 2026 to 14 October 2028 you must not take pāua within 2 km of the shore from Te Huahua / Iron Gate round Tauroa Point to Hunahuna Stream, and taking pāua on scuba is banned nationwide.
No. Spiny red rock lobster may not be taken with a spear.
Anything that is not from the west. Wind and swell from 210° to 330° blow straight onto this coast.
No. Spotted black groper is protected and may not be taken.
