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».
National minimum sizes + a 150 g floor (in the table below); grouper 1/day. Spearfishing is closed all May (ΠΔ 373/1985).
Rules change, and the local Λιμεναρχείο (port authority) may impose local restrictions. Before heading out, check the current rules and the declared archaeological zones (ENALIA).
Spearfishing Chios is built around clear rocky water and lee selection. The south around Emporios and Kato Fana is the first plan in N/NE meltemi, while Trachili, Elinda and Giali give western shelter. The east side near Chios town is convenient, with dive-centre hubs and 3-20 m rock and sand, but it faces the strait. Expect grouper, dentex, sargos and octopus where structure supports them.
Use the island by wind side. South and west are the practical lee zones when the N/NE meltemi is active.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Kato Fana / Vroulidia | Rocky reef and sand | 0-15 m, dropping deeper | Intermediate | Shore or boat | SW tip near Emporios, southern lee and explicitly described as fishing-friendly. |
| Emporios / Mavra Volia | Volcanic black-pebble reef | 3-20 m | Intermediate | Shore or boat | South coast leeward reef with a dive-centre presence. |
| Trachili / Elinda | Named reef | 3-25 m | Intermediate | Shore or boat | Western lee in meltemi and a named top dive area. |
Best timing is Jun and Sep-Oct. When N/NE meltemi is running, avoid forcing the east side and work south or west instead. The Chios port camera helps with the town side but cannot judge Trachili or Giali for you. Greek legal baseline: May is totally banned (ΠΔ 373/1985); no licence since 2014; freediving-only; 5 kg/day. Do not touch antiquities or enter declared underwater archaeological zones.
No. The licence requirement ended in 2014; check the current state sign-up before you go.
Yes. The national May spearfishing ban applies to Chios under ΠΔ 373/1985.
Use the south around Emporios/Kato Fana and the west around Trachili/Elinda/Giali.
Grouper, dentex, sargos and octopus are the main species named for the island.
It is convenient near town, but it faces the strait, so south or west can be better in meltemi.
