12,566-acre Helsinki-Porkkala. North West Finland coastal fishing map with an exact official national water-body boundary, EMODnet 2024 official Finnish hydrographic chart/DTM assessed contours, source-assessed fishing spots, official regional fish evidence, seasonal forage guidance, public-access review and current-rule links. Official Syke VHS 2022 named coastal water in Gulf of Finland. 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 m. The depth chart comes from EMODnet, with national hydrographic source-reference audit official hydrographic-chart depth models, so the contours are chart-derived rather than computer-modeled; no directly measured sounding coverage is claimed. What the data behind the map says about each species, season by season:
Kartalla Helsinki-Porkkala - North West kattaa 5 083 hehtaaria, rantaviivaa 61.8 km, ja saaria on 86. Rantaviiva on voimakkaasti rikkonainen (indeksi 2.4) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Noin 7% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 12.9 km, leveimmillään 8.2 km. Lähin kartoitettu vesi on Pentalanjärvi, 6.4 km pohjoiseen.

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.

Start shallow in spring: european perch sit in 1 to 3.5 m that time of year. Warm water sends them out to 2.5 to 8.5 m; cold water stacks them in 3.5 to 10 m. Top water on the chart: Weed flat, a weed flat in the 2.5 m range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small crankbait (perch pattern) until the fish tell you otherwise.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 3.5 m | midday & dawn | Weed flat (2.5 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 2.5 to 8.5 m | dawn | Sharp break (7 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |

| Talvi | 3.5 to 10 m | midday & dawn | Offshore hump (7 m) | Tungsten jig + maggots, Small balance jig |
Start shallow in spring: zander sit in 1 to 4.5 m that time of year. Warm water sends them out to 4.5 to 11 m; cold water stacks them in 6 to 12 m. Top water on the chart: Offshore hump, an offshore hump in the 7 m range, prime in summer. Fish it in the evening and early morning and you'll meet the bite. Throw a vertical softbait over humps or a deep crankbait until the fish tell you otherwise.

The spring pattern is a shallow one: northern pike in 0.5 to 2.5 m. As the season builds they drop to 2.5 to 6 m, wintering in 1.5 to 4.5 m. Top water on the chart: Weed flat, a weed flat in the 2.5 m range, prime in spring. Time it for early morning and the evening. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.

The spring pattern is a shallow one: atlantic herring in 1.5 to 7.5 m. Midsummer fish sit out in 4.5 to 15 m before dropping to 6 to 18 m for winter. The spot to know is Sharp break, a drop-off in about 7 m of water that rates good for atlantic herring in summer. Plan around early morning and the evening in the warm months. Summer baits: a herring feather rig or a small silver jig gets it done.

Put Sharp break first on the milk run — a drop-off near 7 m that grades good for spring. The feeding windows run early morning and the evening. The summer box starts with a small vertical spoon or a micro jig.
