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.
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.
Leave your email — and the moment a window opens at Ketchikan, we'll send the go / no-go verdict. Email is all we need.

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: 3016 spots across 406 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 mapA current-swept rocky reef, 5–20 m: lingcod and rockfish tight to the structure. Dive slack — outside it the current drags and visibility collapses. Access from the Knudson Cove marina.
Google MapsThe best-known shore dive in the region, about 8 km southeast: the wall starts roughly 30 m out and drops from 3 to 15 m, with lingcod, rockfish, greenling and wolf eels in their dens.
Google MapsA rocky recreation-area shoreline north of town, 3–12 m: rockfish and greenling over stone and kelp. Easy entry with parking close by, good for a warm-up before the current sites.
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».
US spearfishing law is state-by-state. License, spearable species, powerhead rules and distances vary; federal sanctuaries (Gray's Reef, the Keys, Flower Garden Banks) ban spearfishing. Always confirm with the state agency and local ordinances.
Ketchikan has rock entry points such as Mountain Point, Clover Pass / Knudson Cove and Settlers Cove. Rocky walls and current-swept reefs — lingcod, rockfish, greenling and wolf eels; dive Clover Pass at slack. Below you'll find each spot (access, shelter and hazards) and today's forecast.
Brief Jun–Aug window; halibut/lingcod/rockfish, cold low-viz water.
Very cold, 4–12 °C — drysuit; low viz, Cook Inlet hyper-tides.
Expert: cold, Cook Inlet hyper-tides and low viz — slack only, with backup.
Yes — in Ketchikan almost certainly, but the licence is the STATE's, not a federal one: nearly every coastal state requires its own saltwater fishing licence, and several add a free registration or an extra endorsement on top (Florida's free State Reef Fish Survey for reef fish, Texas's saltwater endorsement, California's Ocean Enhancement Validation). Hawaii asks nothing of residents and charges visitors the NRMFL. What may be speared, and with what gear, is state law too — the price and the details depend on the state, so read the «Law» block below.
