16,136-acre Östhammars kustvatten. South Sweden coastal fishing map with an exact official national water-body boundary, EMODnet 2024 CDI-audited mixed survey/composite DTM contours, source-assessed fishing spots, official regional fish evidence, seasonal forage guidance, public-access review and current-rule links. Official SMHI SVAR 2022 named coastal water in Stockholm, Gotland and central Baltic. This child is clipped to the exact source polygon and a trip-scale ownership window. Coverage classes and uncertainty limits are disclosed; this is a fishing-planning chart, not a navigation chart or catch forecast. The water tops out around 153 m. The depth chart comes from EMODnet, with national hydrographic source-reference audit bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
På kartan täcker Östhammars kustvatten - South 6 530 hektar innanför 76.1 km strandlinje, uppbruten av 160 öar. Strandlinjen är kraftigt flikig (index 2.7) — vikar och uddar överallt, vilket mångdubblar den fiskbara kanten. Cirka 5% av vattnet är ~5 m eller grundare, zonen där näringskedjan bor. Från ände till ände mäter vattnet ungefär 18.2 km, som bredast 7.6 km. Närmaste kartlagda vatten är Bornan, 11.3 km åt sydväst.

Occurrence evidence does not promise a catch or establish that retention is legal. Current seasons, closures, protected species, gear rules and local restrictions always control. 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.

Come spring, look for european perch tight to the bank in 1 to 3.5 m. Expect a summer slide to 2.5 to 8.5 m, then a winter hold in 3.5 to 10 m. Start at Offshore hump. It's an offshore hump holding about 5.5 m of water and rates good come summer. Prime time lands in early morning. A drop-shot micro plastics or a small crankbait (perch pattern) is the honest summer answer here.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1 to 3.5 m | midday & dawn | open water | Small jig + curly tail, Inline spinner #1-2 |
| Sommar | 2.5 to 8.5 m | dawn | Offshore hump (5.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Höst | 3 to 10 m | midday | Offshore hump (5.5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Vinter | 3.5 to 10 m | midday & dawn | Offshore hump (5.5 m) | Tungsten jig + maggots, Small balance jig |
Early season northern pike use the shallows, holding in 0.5 to 2.5 m. Expect a summer slide to 2.5 to 6 m, then a winter hold in 1.5 to 4.5 m. Put Shoreline point first on the milk run — a point near 4.5 m that grades good for fall. In summer the feeding windows fall in early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 0.5 to 2.5 m | midday & dawn | open water | #5 inline spinner, Spoon (red/white) |
| Sommar | 2.5 to 6 m | dawn & dusk | Shoreline point (4.5 m) | Bucktail, Weedless spoon over cabbage |
| Höst | 2 to 5.5 m | midday & dawn | Shoreline point (4.5 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Vinter | 1.5 to 4.5 m | midday | Shoreline point (4.5 m) | Large jigging spoon |
Come spring, look for zander tight to the bank in 1 to 4.5 m. Expect a summer slide to 4.5 to 11 m, then a winter hold in 6 to 12 m. Start at Offshore hump. It's an offshore hump holding about 5.5 m of water and rates prime come summer. Prime time lands in the evening and early morning. A vertical softbait over humps or a deep crankbait is the honest summer answer here.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1 to 4.5 m | dusk & dawn | Rock reef (3.5 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Sommar | 4.5 to 11 m | dusk & dawn | Offshore hump (5.5 m) | Vertical softbait over humps, Deep crankbait |
| Höst | 3.5 to 12 m | dusk & night | Shoreline point (11 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Vinter | 6 to 12 m | dusk & dawn | Offshore hump (5.5 m) | Slow blade bait |
When the water first warms, sea trout slide up into 1 to 6 m. Summer is a 4.5 to 15 m game here, winter a 1.5 to 9 m one. Start at Rock reef. It's a rock pile holding about 3.5 m of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a deep-running wobbler or a trolled spoon rigged through the warm months.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1 to 6 m | dawn & dusk | Rock reef (3.5 m) | Slim coastal spoon, Shallow-running wobbler |
| Sommar | 4.5 to 15 m | dawn & dusk | Shoreline point (11 m) | Deep-running wobbler, Trolled spoon |
| Höst | 1 to 7.5 m | dawn & dusk | Shoreline point (4.5 m) | Coastal wobbler, Casting spoon |
| Vinter | 1.5 to 9 m | midday | Rock reef (3.5 m) | Slow coastal spoon, Suspending wobbler |
When the water first warms, atlantic herring slide up into 1.5 to 7.5 m. By summer they slide out to 4.5 to 15 m, and by winter most fish are in 6 to 18 m. If you only fish one area, make it Rock reef: a rock pile around 3.5 m that scores good in spring. In summer the feeding windows fall in early morning and the evening. Keep a herring feather rig or a small silver jig rigged through the warm months.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1.5 to 7.5 m | dawn & dusk | Rock reef (3.5 m) | Small herring feather rig, Micro jig rig |
| Sommar | 4.5 to 15 m | dawn & dusk | open water | Herring feather rig, Small silver jig |
| Höst | 3 to 12 m | dawn & dusk | open water | Small feather rig, Compact silver spoon |
| Vinter | 6 to 18 m | midday | open water | Small silver jig, Sparse feather rig |
Start shallow in spring: european whitefish sit in 3 to 12 m that time of year. Warm water sends them out to 8.5 to 24 m; cold water stacks them in 5.5 to 18 m. Top water on the chart: Rock reef, a rock pile in the 3.5 m range, good in fall. Fish it in early morning and the evening and you'll meet the bite. Throw a small vertical spoon or a micro jig until the fish tell you otherwise.

Access data: Swedish Agency for Marine and Water Management - Bathing Locations and Waters. Confirm conditions and fees locally before you launch.
Season dates, license requirements, and size and bag limits for Sweden waters are set by the Svenska Fiskeregler (official current Swedish fishing-rules service) — and special regulations can apply to Östhammars kustvatten - South specifically, so confirm the current rules before you fish. Check Svenska Fiskeregler and the Swedish Agency for Marine and Water Management immediately before every coastal trip. Area-specific closures, protected spawning areas, minimum and maximum sizes, gear restrictions and species prohibitions can change; recreational fishing for Baltic cod is prohibited during 2026. A mapped depth contour, fishing-spot marker or bathing-site access lead never establishes permission to fish, retain catch, cross private land, park, launch or navigate safely.
