35,005-acre Frederikshavn Coast. North Denmark saltwater fishing map with official Danish Geodata Agency 50 m bathymetry, measured-only fishing spots, DTU-supported fish targets, seasonal forage guidance and public shore-access context. Frederikshavn Coast. North. The Frederikshavn coast and harbor approaches, with reefs, breakwaters and Læsø-facing banks. The water tops out around 102 ft. The depth chart comes from Danish Geodata Agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 35,008 acres of water rimmed by 29.7 miles of bank. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. 12% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 9.4 mi long by 7 mi wide at the broadest reach. Closest neighbour on DepthScout: Skagen Coast - Ålbæk Bay, 10 mi north of here.
The target roster combines the named DTU monitoring area with conservative habitat-compatible Danish regional records. It documents observed or regionally supported occurrence, not equal abundance, a catch rate, or a promised catch in this child. European eel is omitted because recreational eel fishing is currently closed. The roster may combine exact-water monitoring with habitat-filtered official regional evidence; it does not imply that every species is equally abundant throughout the mapped section.

Start shallow in spring: sea trout sit in 3 to 20 ft that time of year. Warm water sends them out to 15 to 50 ft; cold water stacks them in 5 to 30 ft. Top water on the chart: Sharp break, a drop-off in the 46 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a deep-running wobbler or a trolled spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 20 ft | dawn & dusk | Shoreline point (3 ft) | Slim coastal spoon, Shallow-running wobbler |
| Summer | 15 to 50 ft | dawn & dusk | Sharp break (46 ft) | Deep-running wobbler, Trolled spoon |
| Fall | 3 to 25 ft | dawn & dusk | Shoreline point (3 ft) | Coastal wobbler, Casting spoon |
| Winter | 5 to 30 ft | midday | Shoreline point (3 ft) | Slow coastal spoon, Suspending wobbler |
Spring puts atlantic herring in skinny water — 5 to 25 ft is the zone. Warm water sends them out to 15 to 50 ft; cold water stacks them in 20 to 60 ft. Sharp break is the standout, a drop-off at roughly 46 ft, rated good for summer atlantic herring. Plan around early morning and the evening in the warm months. A herring feather rig or a small silver jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|

Spring european flounder on Frederikshavn Coast - North hold shallow, usually 5 to 25 ft. They move out to 6 to 35 ft in summer and finish the year down in 15 to 50 ft. Put Feeding flat first on the milk run — a feeding flat near 26 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a bottom jig with spinner blade.

| Fall | 8 to 40 ft | dusk | Feeding flat (26 ft) | Compact bottom jig |
| Winter | 15 to 50 ft | midday | Sharp break (46 ft) | Small bottom jig |
Start shallow in spring: garfish sit in 1 to 15 ft that time of year. Warm water sends them out to 2 to 20 ft; cold water stacks them in 20 to 60 ft. Top water on the chart: Shoreline point, a point in the 3 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a slim casting spoon or a surface-skipping fly until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & midday | Shoreline point (3 ft) | Slim silver spoon, Small inline spinner |
| Summer | 2 to 20 ft | dawn & dusk | Shoreline point (3 ft) | Slim casting spoon, Surface-skipping fly |

In spring, european plaice run shallow here, mostly 8 to 35 ft. Summer pushes them deeper, 6 to 40 ft, and winter fish settle into 25 to 80 ft. Feeding flat is the standout, a feeding flat at roughly 26 ft, rated prime for spring european plaice. Time it for early morning and the evening. You won't need more than a light spooned bottom rig or a beaded trace most summer days.

Access data: European Environment Agency — 2025 Bathing Water Directive Sites (Denmark). Confirm conditions and fees locally before you launch.
Season dates, license requirements, and size and bag limits for Denmark waters are set by the Danish Agency for Green Transition and Aquatic Environment (current recreational fishing rules) — and special regulations can apply to Frederikshavn Coast - North specifically, so confirm the current rules before you fish. Most anglers using light hand gear need the applicable Danish angling licence, subject to the official age exemptions. Check live species rules, the mapped and unmapped 500-metre stream-mouth conservation belts, local fishing rights, protected areas and posted shore access before every trip. Recreational European eel fishing is currently prohibited, so eel is not promoted as a target here.

Frederikshavn Coast - North is about 102 ft (31 m) deep at its deepest point. The depth chart comes from Danish Geodata Agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Official coastal monitoring from DTU Aqua key-fisher monitoring, 2020–2022 informs the sea trout, atlantic herring, european flounder, garfish, european plaice, whiting, atlantic mackerel, common sole, thick-lipped grey mullet, brill, saithe (coalfish) roster for Frederikshavn Coast - North. The mixed roster combines exact-water records where available with habitat-filtered regional evidence; not every species is documented at this exact water, and it is not a promise of equal abundance or a catch on a particular trip.
Sharp break is the top-rated area: a drop-off in about 46 ft of water that rates prime for sea trout in summer. Every other rated spot, per species and season, is on the map above.
For sea trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
