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.
Rules change. Before heading out, get the recreational licence (SERNAPESCA, pescarecreativa.sernapesca.cl) and respect the RAV closed seasons and regional sizes.
Isla Negra has rock entry points such as Roqueríos Isla Negra. A scenic rocky coast (Neruda's house-museum), rock and sand with good kelp bottom. Below you'll find each spot (access, shelter and hazards) and today's forecast.
Summer to early autumn (Dec–Apr) is calmest; strong upwelling keeps central Chile cold and productive all year.
Cold, ~13–16 °C — 7 mm suit. Strong upwelling; clear but chilly around Quintay, Valparaíso and Algarrobo.
Advanced: cold, swell-exposed central coast — Quintay is the reference, but it demands experience and a thick suit.
Yes — in Isla Negra a Sernapesca recreational licence is mandatory (foreign tourist 1.5 UF/yr; resident 0.7 UF), carry it with your passport. Breath-hold only (rubber or pneumatic speargun — no scuba/compressor). Loco is under a permanent ban and vieja/pejeperro have a 1/day limit. Mind the AMERB areas (don't take benthos). See the guide.
