12,889-acre Latvian Open Baltic Sandy Coast. Sector 04 Latvia coastal fishing map with an exact official national water-body boundary, EMODnet 2024 official Latvian LATCHART hydrographic DTM / traceable CDI assessed contours, source-assessed fishing spots, official regional fish evidence, seasonal forage guidance, public-access review and current-rule links. Official Latvian WFD named coastal or transitional assessment water in Gulf of Riga. 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 41 ft. 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. Species by species, here's what the data says the year looks like.
The drawn water covers 12,885 acres wrapped in 32.1 miles of bank. A middling shoreline index (2) gives it some bays to work without being a maze. The shallow band under 15 ft claims about 34% of the surface — that's where the groceries are. End to end it runs roughly 13.6 mi, about 3.5 mi across. Its nearest charted neighbour, Latvian Open Baltic Sandy Coast - Sector 07, is 7 mi to the southwest.
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 3 to 12 ft. Expect a summer slide to 8 to 28 ft, then a winter hold in 12 to 33 ft. Start at Weed flat. It's a weed flat holding about 5 ft of water and rates prime come spring. Prime time lands in early morning. A drop-shot micro plastics or a small crankbait (perch pattern) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Weed flat (5 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Sharp break (11 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 10 to 33 ft | midday | Sharp break (11 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 12 to 33 ft | midday & dawn | Sharp break (14 ft) | Tungsten jig + maggots, Small balance jig |
Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Put Weed flat first on the milk run — a weed flat near 5 ft that grades prime for spring. 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Weed flat (5 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Weed flat (8 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Sharp break (11 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Weed flat (5 ft) | Large jigging spoon |
Come spring, look for zander tight to the bank in 4 to 15 ft. Expect a summer slide to 15 to 35 ft, then a winter hold in 20 to 40 ft. Start at Sharp break. It's a drop-off holding about 14 ft of water and rates prime come fall. Prime time lands in the evening and early morning. A vertical softbait over humps or a deep crankbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Rock reef (2 ft) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Summer | 15 to 35 ft | dusk & dawn | Sharp break (14 ft) | Vertical softbait over humps, Deep crankbait |
| Fall | 12 to 40 ft | dusk & night | Sharp break (14 ft) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Winter | 20 to 40 ft | dusk & dawn | Shoreline point (19 ft) | Slow blade bait |
When the water first warms, atlantic herring slide up into 5 to 25 ft. By summer they slide out to 12 to 41 ft, and by winter most fish are in 12 to 41 ft. If you only fish one area, make it Sharp break: a drop-off around 14 ft that scores good in summer. 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Weed flat (5 ft) | Small herring feather rig, Micro jig rig |
| Summer | 12 to 41 ft | dawn & dusk | Sharp break (14 ft) | Herring feather rig, Small silver jig |
| Fall | 10 to 40 ft | dawn & dusk | Sharp break (11 ft) | Small feather rig, Compact silver spoon |
| Winter | 12 to 41 ft | midday | Sharp break (14 ft) | Small silver jig, Sparse feather rig |
The spring pattern is a shallow one: european flounder in 5 to 25 ft. As the season builds they drop to 6 to 35 ft, wintering in 12 to 41 ft. Top water on the chart: Sharp break, a drop-off in the 11 ft range, prime in fall. Time it for early morning and the evening. Summer baits: a bottom jig with spinner blade gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dusk | Sharp break (11 ft) | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | Sharp break (11 ft) | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | Sharp break (11 ft) | Compact bottom jig |
| Winter | 12 to 41 ft | midday | Sharp break (14 ft) | Small bottom jig |
When the water first warms, sea trout slide up into 3 to 20 ft. Summer is a 12 to 41 ft game here, winter a 5 to 30 ft one. Start at Sharp break. It's a drop-off holding about 14 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a deep-running wobbler or a trolled spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 20 ft | dawn & dusk | Rock reef (2 ft) | Slim coastal spoon, Shallow-running wobbler |
| Summer | 12 to 41 ft | dawn & dusk | Sharp break (14 ft) | Deep-running wobbler, Trolled spoon |
| Fall | 3 to 25 ft | dawn & dusk | Shoreline point (19 ft) | Coastal wobbler, Casting spoon |
| Winter | 5 to 30 ft | midday | Shoreline point (19 ft) | Slow coastal spoon, Suspending wobbler |

Maritime Administration of Latvia national ports review was reviewed, but no stable government record establishes a public fishing entrance, parking or launch for this exact mapped child. This is an access-evidence gap, not a claim that public access does not exist. Verify land ownership, port and harbour rules, protected areas, local signs, parking, safety, permits and fishing permission before entry.
Private land and private launches need the owner's permission — please ask first.
Season dates, license requirements, and size and bag limits for Latvia waters are set by the Latvijas Vēstnesis (current Latvia angling, crayfish and underwater-hunting rules) — and special regulations can apply to Latvian Open Baltic Sandy Coast - Sector 04 specifically, so confirm the current rules before you fish. Check the live Latvian rules and current Ministry notices before every Baltic Sea or Gulf of Riga trip. Angling-card requirements, coastal hook limits, species possession limits, seasonal protections, eel closures, river-mouth exclusion radii, licensed waters, nature protections, port directions and safe shoreline access can apply. The statutory towpath right is not a promise of a usable entrance, parking or permission through private or working-port land. A hydrographic contour or fishing-spot marker never grants fishing, retention, access or navigation permission.

Latvian Open Baltic Sandy Coast - Sector 04 is about 41 ft (12 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 Latvia national fisheries and coastal monitoring agencies informs the european perch, northern pike, zander, atlantic herring, european flounder, sea trout, european smelt, european eel roster for Latvian Open Baltic Sandy Coast - Sector 04. 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.
Weed flat is the top-rated area: a weed flat in about 5 ft of water that rates prime for european perch in spring. Open the map above to see every rated spot for each species and season.
For european perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
