Activity ratings reflect typical feeding seasons — not legal seasons. Regulations, closures, and size/bag limits change; always check current NH Fish and Game saltwater rules before keeping any fish.
Striped Bass (Atlantic)
Morone saxatilis
Season: Spring and fall migrations; summer in New England (check regs)
Baits: Live or chunk bunker (menhaden), Clams, Live eels
Stripers feed where moving water pushes bait against structure: inlet mouths, jetty tips, bridge shadows, rips and points. Fish the stronger part of the tide, and dawn, dusk and night, especially in summer. Chunks or clams on the bottom from the beach, eels or swimbaits at night along rocks. Circle hooks on bait; release fish carefully, most of the catch goes back.
Bluefish
Pomatomus saltatrix
Season: Spring and fall runs along the beach; summer offshore
Baits: Cut menhaden, Metal spoons and jigs, Topwater plugs
When blues are blitzing bait in the surf you will see birds working and bait spraying; throw a metal or a popper into it. Wire or heavy mono leader, because they bite through everything else and through each other. Bleed and ice them immediately if you plan to eat them.
Atlantic Mackerel
Scomber scombrus
Season: Summer in the Gulf of Maine
Baits: Sabiki or mackerel tree rigs, Small diamond jigs, Small spoons
Schools move along the coast and into harbors in summer. A multi-hook mackerel rig with a small jig below, cast and retrieved or jigged from a wharf or rocks, often catches several at once. Look for birds and bait on the surface; the tide pushing into a harbor often brings them in.
Winter Flounder
Pseudopleuronectes americanus
Season: Early spring in the bays (check regs)
Baits: Sandworms, Bloodworms, Mussels
Small mouths, so small hooks. Fish muddy and sandy bottom in back bays and harbors, and use chum (crushed mussels or clams) to bring them in. Sun-warmed shallows on an afternoon incoming tide are the classic early-season spot.

Surf Rods
Daiwa FT Surf Spinning Rod — 10', 2-Piece Medium
Ten feet is the length most surfcasters land on: enough to clear the first break and keep a bait out past it, still short enough to cast all day without your…

Line & Leader
Sufix 832 Advanced Superline Braid — 20 lb, 300 yd
Seven HMPE fibers plus one GORE Performance Fiber, braided at 32 picks per inch. The GORE fiber is what makes this line quiet through the guides and stubborn…

Terminal Tackle
Eagle Claw Lazer Sharp Offset Circle Sea Hook — 4/0, 50-Pack
The circle hook does the work for you: no strike, just let the rod load and the hook finds the corner of the jaw on its own.

Line & Leader
Sufix Wind-On Fluorocarbon Leader — 50 lb, 11 yd
A braided loop on one end means you connect to your main line without a knot or a swivel, and the leader winds straight through the guides onto the reel.

Predictions come directly from NOAA CO-OPS harmonic predictions for station 8423898 (Fort Point, Portsmouth Harbor) and are the same data used in official tide tables. Actual water levels can vary with storms and barometric pressure, so treat predictions as planning guidance, not navigation data.
Portsmouth sits on the Piscataqua River, one of the fastest-flowing tidal rivers on the East Coast, at the border with Maine. Striped bass come into the river and Great Bay from late spring through fall, and mackerel fill the harbor in summer. Current in the river is very strong; the slack around high and low tide is when most fishing from shore and kayaks works best.
