Spring Striper Run Peaks on the NH Gulf of Maine Coast

What's Biting

What's Next

With water at 52°F and winds light near 10 knots, conditions along the NH coast are as fishable as they get for early June. The migration corridor is fully active per OTW Saltwater's June 2 update, with large stripers pushing north from Boston and feeding on bunker, squid, and river herring. Absent a significant cold front, expect this pattern to hold through the coming weekend.

The Merrimack River mouth should remain the standout location. Per The Fisherman — South Shore MA to ME, the day bite has been most consistent on clams soaked near the river edges, while after dark the action picks up on soft plastics, darters, and bucktails worked through the current. Target incoming tides for fish stacking at the estuary mouth, then stay through the first two hours of the outgoing for bass moving into the bay with the flow. Joppa-area beaches and the shoreline immediately adjacent to the river entrance have been the most consistent producers.

Atlantic mackerel are concentrated on the nearshore ledges, and that bait load is anchoring larger bass to structure longer than they would otherwise stay, per The Fisherman — South Shore MA to ME. For a shot at trophy-class fish, match the forage: large swimming plugs, chunked mackerel, or live-lined offerings over the ledges are the right play. The waning gibbous moon is delivering solid tidal exchange — slightly less extreme than last week's full moon peak, but still strong enough to generate the rip lines and current seams where stripers stack.

As the moon continues to wane over the next three days, dawn and dusk windows will carry more of the action. First light at the river mouth and last light on the ocean-facing beaches are the two slots to prioritize.

Yellowtail and blackback flounder are a secondary option for anyone looking for a change of pace. Capt. Tom of Beauport Fishing Adventures, as reported in The Fisherman — South Shore MA to ME, was specifically planning a yellowtail and blackback trip for the near term, calling the bite reliable.

Bluefish are worth watching by week's end. The Fisherman (Northeast) reported blues arriving across southern New England in late May, tracking the bait schools north. With mackerel thick along the NH coast, the conditions are in place to pull blues through the Gulf of Maine in the coming weeks.

Context

Early June marks the peak of the spring striper push on the NH Gulf of Maine coast. The 52°F water temp from NOAA buoy 44007 sits just below the prime striper comfort zone of 55 to 65°F and is right on pace with historical averages for the region at this point in the season. That temperature gap closes through June, meaning the bite should intensify rather than fade as the month progresses.

What sets 2026 apart is the size and volume of fish in the migration. The Fisherman — South Shore MA to ME has documented stripers to 47 inches throughout the South Shore to ME corridor, and The Fisherman (Northeast) reported 40-pounders in Boston Harbor as early as late May — characterizing the spring push of large fish as one of the strongest in many years. The NH coast sits at the top of the same migratory arc, and a strong caliber of fish at the southern end of the corridor historically translates well to the Gulf of Maine.

The mackerel presence adds a favorable dimension. In seasons when mackerel run thick through the Gulf, larger stripers tend to linger nearshore longer rather than pushing quickly through. That dynamic extends the productive window for NH anglers fishing the ledges and estuary edges compared to leaner bait years.

Shad are also appearing in the Merrimack, per The Fisherman — South Shore MA to ME. Shad runs typically peak in May through early June and historically draw stripers up into river systems and estuary mouths. As long as shad remain present, the Merrimack mouth and the adjacent beach structure should stay productive into mid-June.

By mid-June, when water temps typically push into the upper 50s and low 60s, trophy-class fish begin transitioning from beach and estuary grounds toward offshore structure and deeper ledges. The next two to three weeks represent the best shore-accessible window of the season for consistent large-fish action on the NH coast.
