Today — right on the edge — wave, wind and visibility.

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.

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: 1391 spots across 205 stretches of coast — mainland Portugal, Madeira and the Azores.
See all spotsRelief and bottom type, tides, and the depths of each spot.
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.
Open the seafloor mapThe Drepano point, a pebble tongue pushing into the gulf; rock and slabs 6–14 m on the west side. Sargos, saddled bream, octopus; seabass on the current edge in winter. ⚠️ Current around the tip even in a flat calm — work the lee side and do not cut across the tongue. 6 km east of the bridge. Shore.
Google MapsBelow the village, where the mountain drops into the sea: big boulders and slabs 5–16 m within 50 m of shore, the clearest corner of the Patraikos. Sargos, grouper deeper, octopus. ⚠️ The old national road runs right above — park on the verge, watch the trucks; current sets west towards the strait. Shore.
Cameras, map and reference — to hand as you come up.
National minimum sizes + a 150 g floor (in the table below); grouper 1/day. Spearfishing is closed all May (ΠΔ 373/1985).
SpainSOLO 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 change, and the local Λιμεναρχείο (port authority) may impose local restrictions. Before heading out, check the current rules and the declared archaeological zones (ENALIA).
Patra has rock entry points such as Drepano and Psathopyrgos. Greece's third city, where the Patraikos gulf narrows into the Rio–Antirrio strait. 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 Patra — 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.
The species cards list 21 species with real presence in this basin; the strongest here are common dentex, white seabream, gilthead seabream, European seabass, common octopus and dusky grouper. Minimum sizes in Greece are NATIONAL, not local: white seabream 23 cm · gilthead seabream 20 cm · European seabass 25 cm · dusky grouper 45 cm · red porgy 18 cm · striped seabream 20 cm · brown meagre / corb 25 cm · common octopus 750 g. Species with no EU size carry the 150 g floor only. Grouper (Epinephelus) — max 1/day, not banned (ΠΔ 373/85, art. 2§2).
Yes. May is a TOTAL spearfishing ban for the whole month, every year, across Greece (ΠΔ 373/1985, art. 3§1α) — so in Patra too. It is law in force, not a draft, and there is no local exemption. Plan June to April.
The daily limit is 5 kg, or one trophy heavier than the limit (ΠΔ 373/85, art. 2§2). Grouper (Epinephelus) — max 1/day. Every fish must be at least 150 g (art. 3§2στ), and selling a recreational catch is prohibited (art. 1§7). The limit is national — in Patra it is the same as everywhere in Greece.
No. Freediving only: scuba and any air-supply apparatus are banned — they may not even be carried aboard (ΠΔ 373/85, art. 3§2γ). In Patra the rest of the national frame applies too: 16+, daytime only, ≥200 m from bathers, harbours, moored vessels and marked nets, and a mandatory «Υ.Δ.» buoy you stay within 50 m of. Pneumatic and band guns are allowed; only powerheads are banned.
