The verdict comes from seven water factors and hard safety gates — not ten tabs. Go or stay.

How we score the water

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.

Swell & wave memory
Height, period and direction of the swell, plus the wake of recent storms — an old storm still stirs the water, and the engine remembers.
Wind & gusts
Speed and gusts, hour by hour — wind speed and an onshore push chop the surface and cut visibility.
Tide phase
Timing and range of the tide, calibrated per coast — big spring tides pull the verdict toward caution.
Water temperature
Sea-surface temperature — sharply cold water vetoes a green verdict.
Currents & outflow
Direction and drift of the current — it pushes you, and it drags turbid coastal water across where you dive.
Rain runoff & air clarity
Rain muddies the water inshore through land runoff, while fog and haze cut visibility at the surface.
Coast shape & exposure
How the coast faces the swell — a sheltered cove keeps the water clean; an exposed, head-on point takes a penalty.

Safety gates

  • Thunderstorm forecast — an instant red, no exceptions.
  • An official warning (MeteoAlarm / IPMA) — yellow, or red for the higher ranks.
  • Missing input data — a would-be green is capped to yellow rather than overstated.
  • Strong disagreement between forecast models — a green day is pulled back to yellow.
  • Night hours — forced red; the window is closed after dark.

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.

The water column

Visibility and what drives it — post-storm clearing, river plume, temperature and the thermocline.

What it is

A marine instrument,
go / no-go for solo hunting.

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.

On the rock

The forecast is the plan.
The call is on the rock.

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.

SOLO 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.

Law
  • Pinna nobilis (πίννα, fan mussel) — full ban on taking/killing (Habitats Dir. 92/43 Annex IV; critically endangered).
  • Corals and sponges — recreational taking PROHIBITED (ΠΔ 373/85, art. 1§6).
  • Mediterranean monk seal (Monachus monachus) — strictly protected, keep your distance.
  • Sea turtles (Caretta caretta, Chelonia mydas) — protected, taking/disturbing is PROHIBITED.
  • Seahorses (Hippocampus) — protected.
Safety protocol
  • Sets: watch the wave trains ≥15 min before entering; Hmax ≈ 2×Hs, the wash can run 50 m past the foam line. A lull >10 min with period >12 s = a big set «overdue», do NOT enter; enter right after a full set passes and re-check at minute 30.
  • Exit FIRST: find your exit AND a backup before entering. On a rocky/boulder shore a 0.5 m rise in swell can make the exit impossible — getting pinned/unable to climb out is the main killer.
  • Headland rip: prominent points often have a permanent topographic rip regardless of the model — locate it, enter/exit on the windward side, never swim against it.
  • Cold: wetsuit per the SST chip; the first shiver = a metabolic surge and a drop in breath-hold → get out at the first steady shiver. Cap the session at 45–60 min below 15 °C.
  • Solo discipline: buoy up; tell someone the spot and exit time; conservative breath-hold (never push it in cold/murky/surfy water); visibility <3 m — don't enter.
  • Afternoon wind: on many coasts the wind builds from midday — plan to be out of the water by midday; the chop builds — get out.
  • UV 11:00–15:00 (UVI ≥6): sunscreen and cover up on the surface interval.
  • Solo is a fundamental risk (hypoxic blackout with no buddy). Any doubt = No-go.

FAQ — spearfishing in Kalymnos

Where can I spearfish in Kalymnos?

Kalymnos has rock entry points such as Telendos "Labyrinth", Vathy / Rina fjord (E) and Pserimos — Vathi bay (islet). The historic sponge-diving island and Greece's freediving mecca — deep, clear, low-current water over a rocky seabed of walls, canyons, caverns, reefs and wrecks. Below you'll find each spot (access, shelter and hazards) and today's forecast.

When is the best season in Kalymnos?

A long, mild season, June to October (May closed nationally); the warm south-east Aegean, less meltemi-battered than the Cyclades.

How cold is the water in Kalymnos?

Warm, clear blue water (~25–27 °C in summer), tideless; good visibility over rock and reef around Rhodes, Kos and Kalymnos.

Is Kalymnos good for a beginner?

Easy to moderate: warm, clear water and plenty of sheltered coast, with deeper drop-offs for those who want them.

Do I need a licence in Kalymnos?

No paid licence is needed in Kalymnos — 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.
