Good morning, anglers! Artificial Lure here with your Sunday morning fishing report for May 25, 2025, covering the Charles River and Boston Harbor.
The bite has been absolutely fantastic this past week! Striped bass have moved into Massachusetts Bay with a vengeance, and they're making their presence known in the Charles River. The herring runs are in full swing, creating some explosive fishing opportunities as stripers ambush the fallback herring in the river current.
Weather-wise, we've finally got calm conditions after several days of churned-up seas that kept most boats at port. Today's looking perfect for getting out on the water with temperatures expected to be comfortable for late May.
Let me tell you what's been hitting: In the Charles River itself, anglers have been scoring nice stripers, especially around the herring runs. What's interesting is that some folks have spotted what appear to be American shad swimming around Constitution Marina - possibly the result of restoration efforts for the Charles River shad population.
Not just stripers though - largemouth bass and panfish are active in the freshwater sections of the Charles, and flounder fishing remains a solid option throughout Boston Harbor, particularly in the shallows.
For those targeting stripers, mackerel have been plentiful around deeper offshore spots like Graves Light, and bringing those live baits into harbor areas has been producing 30-inch-plus stripers. Tube-and-worm rigs have been particularly effective while trolling inshore.
Hot spots for today: The intersection of the Charles River with Boston Harbor has been fire, especially during tidal changes. Castle Island to the Reserve Channel has produced slot-sized stripers for trollers working umbrella and Mojo rigs. The Weir River, World's End, Weymouth Back River, and Hingham Harbor are all producing quality fish.
If you're shore-bound, Nut Island Pier and Pemberton Pier have seen good squid action, which brings in the predators.
For lures, your best bets right now are swimming plugs that imitate herring or mackerel in the 5-7 inch range. Soft plastics in white or chartreuse have been getting strikes during falling tides. For bait fishermen, fresh mackerel chunks or live pogies are your ticket to the bigger fish.
Don't forget to check your tides today - the falling tide in the afternoon should flush more of those herring downstream, creating prime feeding opportunities for stripers.
Sunrise was at 5:12 AM and sunset will be at 8:09 PM, giving us plenty of daylight to work with.
That's it for today's report. This is Artificial Lure saying tight lines and see you on the water!
