24,487-acre Onsala 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 West Coast and Kattegat. 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 48 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. Every species below gets its seasonal read from the same numbers driving the chart.
På kartan täcker Onsala kustvatten - South 9 910 hektar innanför 89.2 km strandlinje, uppbruten av 128 öar. Ett strandindex på 2.5 betyder en labyrint av vikar och uddar: många fler kastmål än en rund sjö i samma storlek. Ungefär 3% av ytan är grundare än ~5 m — där finns vegetationen och betesfisken. Räkna med 15.8 km vatten från ena änden till den andra och 9.8 km på bredden. Onsala kustvatten - North ligger 12.9 km åt norr — närmaste grannvatten på kartan.
Gratis interaktiv fiskekarta — Onsala kustvatten — South, Sverige: källgranskade kustdjupkurvor (99 % direktmätt) ner till 48 m (159 fot), och de bästa fiskeplatserna för havsöring, sill och strömming, makrill med flera. Djupkartan är modellberäknad från sjöns verkliga strandlinje och största djup — använd den som vägledning, aldrig för navigation.
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.

The spring pattern is a shallow one: sea trout in 1 to 6 m. As the season builds they drop to 4.5 to 15 m, wintering in 1.5 to 9 m. Top water on the chart: Rock reef, a rock pile in the 2 m range, prime in spring. Time it for early morning and the evening. Summer baits: a deep-running wobbler or a trolled spoon gets it done.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1 to 6 m | dawn & dusk | Rock reef (2 m) | Slim coastal spoon, Shallow-running wobbler |
| Sommar | 4.5 to 15 m | dawn & dusk | Sharp break (13 m) | Deep-running wobbler, Trolled spoon |
| Höst | 1 to 7.5 m | dawn & dusk | Shoreline point (2.5 m) | Coastal wobbler, Casting spoon |
| Vinter | 1.5 to 9 m | midday | Rock reef (2 m) | Slow coastal spoon, Suspending wobbler |
In spring, atlantic herring run shallow here, mostly 1.5 to 7.5 m. Summer pushes them deeper, 4.5 to 15 m, and winter fish settle into 6 to 18 m. Sharp break is the standout, a drop-off at roughly 13 m, rated good for summer atlantic herring. Time it for early morning and the evening. You won't need more than a herring feather rig or a small silver jig most summer days.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1.5 to 7.5 m | dawn & dusk | Rock reef (2 m) | Small herring feather rig, Micro jig rig |
| Sommar | 4.5 to 15 m | dawn & dusk | Sharp break (13 m) | Herring feather rig, Small silver jig |
| Höst | 3 to 12 m | dawn & dusk | Sharp break (13 m) | Small feather rig, Compact silver spoon |
| Vinter | 6 to 18 m | midday | Sharp break (13 m) | Small silver jig, Sparse feather rig |
Early season atlantic mackerel use the shallows, holding in 1.5 to 14 m. Expect a summer slide to 4.5 to 24 m, then a winter hold in 9 to 37 m. Put Sharp break first on the milk run — a drop-off near 13 m that grades good for summer. In summer the feeding windows fall in early morning and the evening. Tie on a feather rig or a small vertical jig and you're in the game.

The spring pattern is a shallow one: garfish in 0.5 to 4.5 m. As the season builds they drop to 0.5 to 6 m, wintering in 6 to 18 m. Top water on the chart: Shoreline point, a point in the 2.5 m range, prime in spring. Time it for early morning and the evening. Summer baits: a slim casting spoon or a surface-skipping fly gets it done.

| Höst | 2.5 to 9 m | dawn & dusk | Shoreline point (2.5 m) | Weighted slim spoon, Small silver jig |
| Vinter | 6 to 18 m | midday | Sharp break (13 m) |
Early season european flounder use the shallows, holding in 1.5 to 7.5 m. Expect a summer slide to 2 to 11 m, then a winter hold in 4.5 to 15 m. Put Sharp break first on the milk run — a drop-off near 13 m that grades good for fall. In summer the feeding windows fall in early morning and the evening. Tie on a bottom jig with spinner blade and you're in the game.
| Säsong | Djup | Bästa tid | Börja vid | Beten |
|---|---|---|---|---|
| Vår | 1.5 to 7.5 m | dusk | open water | Small bucktail dragged on bottom |

| Höst | 2.5 to 12 m | dusk | Sharp break (13 m) | Compact bottom jig |
| Vinter | 4.5 to 15 m | midday | Sharp break (13 m) | Small bottom jig |
Spring puts european plaice in skinny water — 2.5 to 11 m is the zone. Warm water sends them out to 2 to 12 m; cold water stacks them in 7.5 to 24 m. Plan around early morning and the evening in the warm months. A light spooned bottom rig or a beaded trace covers the summer program.
| Säsong | Djup | Bästa tid | Börja vid | Beten |

| Vår | 2.5 to 11 m | dusk | open water | Beaded flowing trace |
| Sommar | 2 to 12 m | dawn & dusk | open water | Light spooned bottom rig, Beaded trace |
| Höst | 3 to 15 m | dusk | open water | Beaded bottom trace |
| Vinter | 7.5 to 24 m | midday | open water |

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 Onsala 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.

Onsala kustvatten - South is about 159 ft (48 m) deep at its deepest point. 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.

Official coastal monitoring from Sweden national fisheries and coastal monitoring agencies informs the sea trout, atlantic herring, atlantic mackerel, garfish, european flounder, european plaice, saithe (coalfish), atlantic cod roster for Onsala kustvatten - South. 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.
Rock reef is the top-rated area: a rock pile in about 7 ft of water that rates prime for sea trout in spring. The map above holds the full rated-spot list for every 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.
Fishing on Onsala kustvatten - South is regulated by the Svenska Fiskeregler (official current Swedish fishing-rules service). Check the official Sweden regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
