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.
Where to get in, where to hunt
Wind, wave and the swell windows — when to go and the best hours.
The day is picked above, in the hero. Here are that day's windows, the hour-by-hour map and the trends. Tap a window to break down the conditions.
Visibility and what drives it — post-storm clearing, river plume, temperature and the thermocline.
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: 1152 spots across 189 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.
Scouted entries, coloured by today. The colour is the sea state at the spot, not a guarantee: the wash and a slippery entry you judge on site.

Google MapsSOLO 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.
Cameras, map and reference — to hand as you come up.
Check the cam BEFORE you leave. Foam, brown/green murk, or waves washing the entry rocks = No-go. At night/in fog the cam is useless — treat it as «unknown», NOT «green».
Rules change and fees/seasons are updated yearly. Before heading out, check the Ministry of Agriculture fisheries portal (ribarstvo.mps.hr) and get the SPORT licence (the annual via HSSRM/a club); a speargun without it is illegal.
Novigrad is a compact Istrian plan. Rt Zub / Karpinjan is a shallow reef flat, listed for gilthead bream and sea bass. The Novigrad south rock wall by Rt Mujela is a different shape, with dentex and white seabream. Access details and numeric depths are not described for either spot. Both have medium solo severity and a yellow safety rating. Because the aspect is about 270 degrees, west and southwest sea are central to the go/no-go decision.
There are only two rows, so do not blur them. Karpinjan is shallow reef flat; Rt Mujela is the south rock-wall option.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Rt Zub / Karpinjan | Shallow reef flat | Shallow, no number given | Medium; yellow safety rating | Not described | Gilthead bream and sea bass. Shallow water still needs clean visibility and a safe exit. |
| Novigrad – južna stijena | South rock wall by Rt Mujela | No numeric depth | Medium; yellow safety rating | Not described | Dentex and white seabream. This is not the same plan as the Karpinjan flats. |
Novigrad’s aspect is about 270 degrees, with a bad sector of 165-285 degrees and the worst direction around 225 degrees. In the northern Adriatic, tide is small; wind, swell and visibility make the decision. Two cameras show the harbour basin and waterfront, but they do not prove the reef-flat exit is safe. Under NN 48/2026, spearfishing with a speargun requires the sport sea-fishing licence. It is breath-hold only, daylight only, minimum age 16, with a mandatory marker buoy and no more than two spearguns per diver. Grouper is closed from 1 July to 31 August.
Two: Rt Zub / Karpinjan and the south rock wall by Rt Mujela.
Gilthead bream and sea bass are listed for the shallow reef flat.
No numeric depth is given for either Novigrad row.
Yes. Novigrad has harbour-basin and waterfront camera views.
The sport sea-fishing licence is needed for spearguns; an ordinary recreational licence does not cover them.
