Fall Push Builds Along the NH Coast as Bass Move North

What's biting

What's next

Nothing in this week's single buoy read suggests a sharp swing coming — 59°F water and light winds at 44007 are square in the middle of what mid-September should look like on this stretch of the Gulf of Maine, so the pattern already showing up to our south likely keeps building rather than resetting. The Fisherman (Northeast)'s New England forecast already flags striper action "organizing into a full-on fall run with isolated blitz action," and it specifically calls that out as strongest to the north — which puts the NH coast right in the path over the next several days.

Watch the bait first. Dave Anderson's report out of the South Shore Massachusetts to Maine corridor has mackerel flooding back inshore into harbors and bays, which is exactly the trigger that's been waking up striper catches down that stretch — Belsan's Bait and Tackle is already seeing several fish north of 40 inches on live bait, plugs, and plastics. If that bait keeps pushing north on schedule, expect the same striper response to show up on NH beaches and river mouths within the coming week, likely strongest around dawn and dusk given there's no tide data this cycle to pin an exact peak.

For boat anglers, the groundfish side of the report is the more reliable near-term bet. Beauport Fishing Adventures notes codfish action ramping up further north with pollock and haddock holding in decent numbers — a pattern that tends to hold steady through cooler water rather than spike and fade, so it should be a dependable option through the weekend regardless of what the inshore bait does.

Squid are still mostly offshore per the same South Shore reports, so don't expect a strong squid-and-bass combo bite inshore just yet — that typically follows once water temps drop another few degrees. With a waxing crescent moon building toward the first quarter, tidal swings stay moderate this week; we're not expecting a dramatic bite trigger from the moon phase itself, so the mackerel push and cooling water remain the two things worth watching heading into the weekend.

Context

Mid-September on the NH stretch of the Gulf of Maine typically means the striped bass fall migration is underway and groundfish — cod, pollock, haddock — are settling into their cooler-water bite as inshore temperatures ease off the summer peak. A 59°F reading at buoy 44007 is consistent with that seasonal timeline, neither notably warm nor cold for the date, which suggests this year's transition is running roughly on schedule rather than early or late.

The regional feeds back that up in a general way: The Fisherman (Northeast)'s New England forecast describes striper action organizing into a fall run "particularly to the north," and the South Shore Massachusetts to Maine reports show the classic sequence — mackerel and other bait pushing inshore, stripers responding, groundfish action building further up the coast — playing out in the usual order rather than a scrambled one. That's a notably different picture from what the same forecast describes for the albie run further south this year, which it calls "weird" and inconsistent in its opening weeks; nothing in the data here points to that kind of disruption reaching the NH coast's cod/pollock/haddock and striper pattern.

We don't have a direct NH-specific report in this week's feeds to compare against a prior season, so treat the above as a regional read rather than a hard local comparison — the closest testimony comes from adjacent Maine and Massachusetts coverage, not NH boats or shops directly. Nothing in the buoy data or the angler intel this cycle flags an anomaly worth a season note.
