2,583-acre Hyannis Harbor fishing map with NOAA BlueTopo survey contours (90.75% measured, 100% assessed), charted rock and wreck structure, regional fish-survey occurrence, sourced forage timing and verified public access. The water tops out around 26 ft. The depth chart is built from real agency bathymetry referenced to NAVD88; directly measured coverage remains distinguished from source interpolation. The channels, holes and drop-offs come from the source data, not a distance-from-shore model. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 2,580 acres wrapped in 8.1 miles of bank. Its 1.1 shoreline index means few bank features; the contours below do the pattern work. The shallow band under 15 ft claims about 61% of the surface — that's where the groceries are. Figure 2.8 mi of water from one end to the other, 2.3 mi at the beam. Centerville Harbor sits 3 mi west — the closest neighbouring chart.
In spring, striped bass run shallow here, mostly 5 to 20 ft. Midsummer fish sit out in 8 to 26 ft before dropping to 8 to 26 ft for winter. Summer striped bass concentrate at Surveyed channel edge, a prime-rated drop-off around 12 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a flutter spoon (deep) or an umbrella rig (trolled) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Surveyed channel edge (12 ft) | Bucktail jig + trailer, Walking topwater (dawn) |
| Summer | 8 to 26 ft | dawn & dusk | Surveyed channel edge (12 ft) | Flutter spoon (deep), Umbrella rig (trolled) |
| Fall | 7 to 26 ft | dawn & dusk | Surveyed channel edge (12 ft) | Topwater walker, Jerkbait |
| Winter | 8 to 26 ft | midday | Surveyed channel edge (12 ft) | Alabama rig (slow), Flutter spoon |
Come spring, look for bluefish tight to the bank in 3 to 20 ft. They move out to 4 to 26 ft in summer and finish the year down in 8 to 26 ft. If you only fish one area, make it Surveyed channel edge: a drop-off around 12 ft that scores prime in summer. Best bite is early morning and the evening. A popper (early/late) or a metal jigs in the rips is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 20 ft | dawn & dusk | Shallow feeding flat (20 ft) | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 4 to 26 ft | dawn & dusk | Surveyed channel edge (12 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 25 ft | dawn & midday | Shallow feeding flat (20 ft) | Pencil popper, Big metal |
| Winter | 8 to 26 ft | midday | Surveyed channel edge (12 ft) | Metal jig worked slow (southern waters) |
The spring pattern is a shallow one: summer flounder (fluke) in 5 to 25 ft. Midsummer fish sit out in 6 to 26 ft before dropping to 8 to 26 ft for winter. The spot to know is Surveyed channel edge, a drop-off in about 12 ft of water that rates prime for summer flounder (fluke) in summer. Plan around midday and early morning in the warm months. Summer baits: a bucktail (1-3 oz by drift speed) or a gulp grub on jighead gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | midday & dawn | Surveyed channel edge (12 ft) | Bucktail + Gulp swimming mullet, Hi-lo rig + squid strip |
| Summer | 6 to 26 ft | midday & dawn | Surveyed channel edge (12 ft) | Bucktail (1-3 oz by drift speed), Gulp grub on jighead |
| Fall | 7 to 26 ft | midday | Surveyed channel edge (12 ft) | Heavier bucktail on the lumps, Big Gulp 6" grub |
| Winter | 8 to 26 ft | midday | Surveyed channel edge (12 ft) | Slow bottom rig + strip |
In spring, black sea bass run shallow here, mostly 7 to 26 ft. Summer keeps them at 7 to 26 ft, and they winter in 8 to 26 ft. Spring black sea bass concentrate at NOAA charted underwater rock, a prime-rated rock pile around 9 ft. Fish it in midday and early morning and you'll meet the bite. You won't need more than a bucktail + grub or a diamond jig + squid teaser most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 7 to 26 ft | midday & dawn | NOAA charted underwater rock (9 ft) | Hi-lo rig + squid, 1-2 oz bucktail + Gulp |
| Summer | 7 to 26 ft | midday & dawn | NOAA charted underwater rock (9 ft) | Bucktail + grub, Diamond jig + squid teaser |
| Fall | 7 to 26 ft | midday | NOAA charted underwater rock (9 ft) | 3-4 oz vertical jig (deep), Double-teaser rig |
| Winter | 8 to 26 ft | midday | NOAA charted underwater rock (9 ft) | Heavy hi-lo rig on deep wrecks |
Early season tautog (blackfish) use the shallows, holding in 5 to 25 ft. Expect a summer slide to 7 to 26 ft, then a winter hold in 8 to 26 ft. Put Dangerous NOAA charted wreck first on the milk run — a wreck near 13 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a 1/2-1 oz tog jig + crab and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | midday & dawn | Dangerous NOAA charted wreck (13 ft) | Tog jig + green crab half, Bare jig + clam (early) |
| Summer | 7 to 26 ft | dawn | Dangerous NOAA charted wreck (13 ft) | 1/2-1 oz tog jig + crab |
| Fall | 5 to 26 ft | midday | Dangerous NOAA charted wreck (13 ft) | Tog jig + whole green crab, Old-school rig + double crab (deep) |
| Winter | 8 to 26 ft | midday | Dangerous NOAA charted wreck (13 ft) | Heavy jig + crab on deep structure |
Structure-wise the chart holds 66 features, led in depth by Surveyed channel edge at roughly 21 ft.

Hyannis Harbor is about 26 ft (8 m) deep at its deepest point. The depth chart is built from real agency bathymetry referenced to NAVD88; directly measured coverage remains distinguished from source interpolation. The contours reflect measured and quality-assessed source depths.
Anglers target striped bass, bluefish, summer flounder (fluke), black sea bass, tautog (blackfish) on Hyannis Harbor.
Surveyed channel edge is the top-rated area: a drop-off in about 12 ft of water that rates prime for summer flounder (fluke) in summer. Open the map above to see every rated spot for each species and season.
For striped bass, 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.
