Compiled by the spearo sea-state engine
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).
Nafplio has rock entry points such as Romvi Drop-Off, Romvi South and Karathona. Sheltered, shallow, west-facing head of the Argolic Gulf: softer visibility, sand, seagrass and rocky islets. Below you'll find each spot (access, shelter and hazards) and today's forecast.
Long season, June to October (May closed nationally), peaking in summer; the west and east coasts give a lee for most winds.
Clear, warm mediterranean water, tideless; the Ionian west is a touch greener, the Aegean east bright blue.
Mostly easy to moderate: pick the coast sheltered from the day's wind and you'll find calm, clear rock all summer.
No paid licence is needed in Nafplio — the amateur one was abolished (Law 4256/2014), but a free ΟΣΠΑ registration is being introduced (check gov.gr). Breath-hold only (no scuba), a mandatory «Υ.Δ.» buoy, 16+, daytime only, and the whole of May is closed. See the guide.
