Maine & New Hampshire Coast migration calendar.

NortheastMaineNew Hampshire2 species tracked

The northern terminus of the Atlantic striped bass migration. Cold water keeps the season short — fish typically arrive in late May and depart by mid-October — but the bass that reach this far north tend to be larger, and bluefish push the same windows.

Verify with current conditions

Migration timing varies year over year with water temperature, weather, and bait movement. Cross-reference with NOAA marine forecast and a local source before planning a trip.

Regional notes — top species

Striped Bass in Maine & New Hampshire Coast

Striped bass complete their northward migration into the Gulf of Maine by late May, peak from mid-June through August, and depart south by mid-October. Resident summer fish hold on coastal structure once water hits 60°F.

Bluefish in Maine & New Hampshire Coast

Bluefish push north into Maine waters with the warming water — June arrivals, July–August peak, departure by mid-October. Heavily tied to bunker and herring schools.
