Every winter, anticipation builds for the arrival of migrating striped bass. Each year is different, and exact timing seems to be strongly influenced by water temperatures along the Atlantic coast. By tracking fishing reports from charter captains, contributors, anglers and readers at OnTheWater.com, we have been mapping the striped bass spring migration from the Mid-Atlantic to Maine since 2015. Each year has been very different and provided some interesting insight into the timing of the striper migration.

2015: A historically snowy and cold winter kept water temperatures cool well into the spring, delaying the striped bass migration and resulting in later arrivals than most fishermen could recall in recent history. Yet, by mid-June, big striped bass were reported from the Jersey Shore to southern Maine.

2016: A strong El Nino blessed the East Coast with a mild winter, and the migration got off to an early start. Big bass appeared in Raritan Bay by mid-April, and fresh schoolie stripers arrived early to New England. However, by June, the maps for 2015 and 2016 looked almost identical.

2017: Bitter cold weather in March delayed the striper spawn in the Chesapeake and slowed the start of the migration. In mid-May, big post-spawn bass showed up off northern New Jersey to chow down on bunker. Remarkably, schools of bass, including many fish over 30 pounds, arrived in Cape Cod waters earlier than usual, and it seemed as if large numbers of fish bypassed Long Island waters.

2018: Another cold spring delayed the striper spawn and had many anglers lamenting that the migration was running about two weeks behind schedule. While this meant a slow start in parts of Cape Cod and Massachusetts, it also meant a longer spring season for anglers in Western Long Island Sound and off Long Island’s South Shore.

2019: Although stripers are typically more bait-oriented during the fall run, acres of menhaden caused bass of all sizes to congregate around northern New Jersey and Long Island before continuing north after a temperate winter.

2020: Late March saw the start of the pandemic while a push of large bass in the 20-pound range hit New Jersey’s shores. Schoolies flooded the coast in the following weeks, and trophy bass were plucked from beneath bunker schools throughout the summer into early autumn.

2021: Large schools of bunker and mild water temperatures nearly mirrored 2020’s spring migration. However, the widespread absence of big bass left many anglers concerned that they were seeing the documented decline of larger stripers in real time.

Striped Bass Migration Basics

Striped bass are anadromous—they live their adult lives in the ocean but migrate into brackish bays and freshwater rivers to spawn. On the East Coast, there are three major spawning grounds: the tributaries of Chesapeake Bay, upper Delaware Bay/Delaware River, and the Hudson River in New York.

Smaller striped bass (schoolies) are the first to arrive along the coast in spring. This is because smaller, immature striped bass bypass the spawning grounds on their way north. Male striped bass reach sexual maturity at two or three years of age (at approximately 16 to 20 inches of length), and female striped bass mature at four to six years of age (at approximately 24 to 28 inches of length).

The timing of the arrival of larger striped bass, the 28-inch-plus spawning fish, depends on the timing of the spring spawn. Spawning takes place earliest in Chesapeake Bay, as striped bass move from their wintering grounds off North Carolina and Virginia into the Bay in mid-March. Spawning is slightly later in the Delaware River, taking place in early April, and a few weeks later in the Hudson River, typically mid- to late April.

Through tagging studies, scientists have found that individuals from different spawning stocks tend to exhibit different migration habits. The Chesapeake Bay spawning areas produce most coastal migratory striped bass (estimated 70-90%), and fish hatched in the Chesapeake Bay exhibit more extensive migrations. Those that hatch in the Hudson River generally do not migrate beyond Cape Cod, Massachusetts, to the north and Cape May, New Jersey, to the south. Every winter, anticipation builds for the arrival of migrating striped bass. Each year is different, and exact timing seems to be strongly influenced by water temperatures along the Atlantic coast.
