76,647-acre Bornholm. Northwest Coast 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. Bornholm. Northwest Coast. Bornholm's west coast around Rønne, with rocky points, harbor structure and Baltic depth transitions. The water tops out around 199 ft. The depth chart comes from Danish Geodata Agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Bornholm - Northwest Coast runs 76,622 acres with 62.1 miles of edge. Index 1.6 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 2% of this chart. End to end it runs roughly 18.1 mi, about 14.6 mi across. For a second option, Bornholm - Southwest Coast lies 15 mi south.
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 52 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 | open water | Slim coastal spoon, Shallow-running wobbler |
| Summer | 15 to 50 ft | dawn & dusk | Sharp break (52 ft) | Deep-running wobbler, Trolled spoon |
| Fall | 3 to 25 ft | dawn & dusk | open water | Coastal wobbler, Casting spoon |
| Winter | 5 to 30 ft | midday | open water | 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 52 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 | 5 to 25 ft | dawn & dusk | open water | Small herring feather rig, Micro jig rig |
| Summer | 15 to 50 ft | dawn & dusk | Sharp break (52 ft) | Herring feather rig, Small silver jig |
| Fall | 10 to 40 ft | dawn & dusk | open water | Small feather rig, Compact silver spoon |
| Winter | 20 to 60 ft | midday | Sharp break (52 ft) | Small silver jig, Sparse feather rig |
Spring european flounder on Bornholm - Northwest Coast 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 DDM measured flat first on the milk run — a feeding flat near 27 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dusk | DDM measured flat (27 ft) | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | DDM measured flat (27 ft) | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | DDM measured flat (27 ft) | Compact bottom jig |
| Winter | 15 to 50 ft | midday | Sharp break (52 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: Sharp break, a drop-off in the 52 ft range, good in winter. 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 | open water | Slim silver spoon, Small inline spinner |
| Summer | 2 to 20 ft | dawn & dusk | open water | Slim casting spoon, Surface-skipping fly |
| Fall | 8 to 30 ft | dawn & dusk | open water | Weighted slim spoon, Small silver jig |
| Winter | 20 to 60 ft | midday | Sharp break (52 ft) |
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. DDM measured flat is the standout, a feeding flat at roughly 27 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 35 ft | dusk | DDM measured flat (27 ft) | Beaded flowing trace |
| Summer | 6 to 40 ft | dawn & dusk | DDM measured flat (27 ft) | Light spooned bottom rig, Beaded trace |
| Fall | 10 to 50 ft | dusk | DDM measured flat (27 ft) | Beaded bottom trace |
| Winter | 25 to 80 ft | midday | open water |
In spring, whiting run shallow here, mostly 15 to 55 ft. Summer pushes them deeper, 20 to 70 ft, and winter fish settle into 15 to 70 ft. Time it for early morning. You won't need more than a small vertical jig 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 Bornholm - Northwest Coast 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.

Bornholm - Northwest Coast is about 199 ft (61 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 Bornholm - Northwest Coast. 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.
DDM measured flat is the top-rated area: a feeding flat in about 27 ft of water that rates prime for european flounder in summer. Scroll up to the map for the complete spot list by species and season.
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.
