Memorial Day Weekend Report: Cape Cod Bay and the South Side
Memorial Day weekend on Cape Cod has anglers catching big striped bass inside Cape Cod Bay and smaller, but more aggressive fish along the south side. Ian McPartland of the Goose Hummock updates us on bass behavior, bait, water temperature, and tidal conditions.
Ian's report covers two distinct fisheries — Cape Cod Bay and the south side of Cape Cod — along with some thoughtful tactical advice that any surfcaster or boat angler can put to use over the long holiday weekend.
Cape Cod Bay
If you've been paying attention to Cape Cod Bay this spring, you already know it has been the star of the show. Ian made no secret of it: Cape Cod Bay has delivered the most consistent action in terms of both size and numbers. Large stripers have been stacked up inside the bay, and this has been driving the fishing conversation on the Cape for the better part of three weeks heading into the holiday weekend.
One particular zone generating significant buzz is the flats area inside Cape Cod Bay. Drone footage shared on the My Fishing Cape Cod website confirmed a biomass of fish working the flats, which is exciting in principle — but the catch ratio relative to the number of fish being seen has been lower than expected according to Ian. The reason, comes down to bait.
Typically at this point in the season, Cape Cod Bay stripers are keyed in on herring moving through the canal and out into the bay. That's a pattern Cape Cod anglers know well, and it calls for larger, herring-profile presentations — think big soft plastics, larger swimmers, and herring-colored patterns. This year, however, a wrinkle has emerged. The bass on the flats appear to be dialed in on very small sand eels rather than herring, and that shift is making for a considerably more technical bite.
"You can have an elephant eating peanuts kind of situation," Ian explained. Big fish are present, but they're feeding on tiny baits — and matching that presentation accurately is the difference between a great night and a frustrating one.
Matching the Hatch
When the bait profile on the flats shifts from herring to sand eels or small bait, it requires a real recalibration of your approach. Ian shared his go-to tactics for making that adjustment, and they're worth exploring and planning for as you prepare for your next surfcasting session.
Downsize Your Leader
The first and most immediate change Ian recommends is dropping your leader diameter. He'll typically go down to 20-pound fluorocarbon when fish are behaving fussily on small bait. Heavier leader material can be a deal-breaker with wary, well-fed fish keyed in on tiny profile baits.
Albie Snacks in Both Sizes
Ian has been leaning heavily on the Albie Snack, a small soft plastic that does a convincing job imitating sand eels and small baitfish. He throws the standard size from the beach during lower water and switches to the larger version as the tide pushes up. The Albie Snack's simple, slender profile has been fooling fish that want nothing to do with larger presentations.
The Popper-Fly Tandem
This is where Ian's approach gets genuinely creative. When fish are locked on super small sand deals and conventional lures aren't getting the job done, he builds a tandem rig using a surface popper with a fly trailer. The setup works like this:
Ian uses a five-inch Tsunami Talking Popper and removes the rear treble hook entirely. In place of that hook, he ties a short fly leader directly to the rear hook hanger using a hard clinch knot — not a loop knot. The key distinction is important: he specifically avoids a loop knot because he wants the fly to trail directly behind the plug without swinging around the body of the lure or tangling in the main braid. He runs roughly a two-foot leader to the fly, tied with hard knots at both ends to keep everything locked in position. The popper serves as a long-distance casting platform and a fish attractor, while the fly trailing behind it imitates the small baitfish the stripers are actually hunting.
It's not a setup that produces a fish on every cast, but it gives anglers something productive to throw when nothing else seems to be working, and it can be fished from the surf to cover significant ground.
Boat Fishing in Cape Cod Bay
While the shore anglers are working the flats and the beach, the boat fishermen have found their own productive piece of the puzzle. Reports from boat anglers — including Ian's boss Phil Howarth, who shared a report on the Goose Hummock social media channels — indicate that larger fish are moving out into deep water in the 60 to 80 foot range.
This is a natural response to the conditions earlier in the week. When water temperatures climb and skies are bright and sunny, larger stripers push off the shallow flats and settle into deeper, cooler, darker water during daylight hours. That actually creates an opportunity for boat anglers willing to target them vertically.
In that depth range, diamond jigs come into their own. Ian pointed to the effectiveness of tandem diamond jig setups — rigging a diamond jig with a soft plastic trailer as a way to reach fish sitting 40 to 50 feet down in 80 feet of water. These mid-column, mid-day bites are largely a boat angler's game; shore anglers simply can't reach fish at that depth or distance. But for those with a boat and the right jigs in the box, this represents an underutilized daytime bite window when the surface bite slows.
Ian noted that a friend this week was surrounded by big fish busting on top — a beautiful problem to have — but couldn't get them to commit to any standard offering. Ian's advice: drop down to a light rod, throw an Albie Snack, and accept that you may not catch one every cast, but you'll get bites you wouldn't otherwise get.
South Side Schoolies
For those frustrated by finicky flats fish, Ian offered some encouraging news from the south side of Cape Cod. He spent a productive night last night working a sound side harbor location, and while the fish weren't the trophy-class bass showing up inside the bay, the experience was a welcome change of pace.
The largest fish of the night ran about 32 inches, but what the session lacked in size it more than made up for in action and attitude. These fish were aggressive, hungry, and willing to eat. Ian had the spot entirely to himself, which, on a Cape Cod holiday weekend, is practically a miracle in itself.
This is significant news for the broader health of the fishery this season. Through the first two weeks of our MFCC Podcast Fishing Reports, multiple guests had noted an unusual absence of schoolie-sized fish — the first fish of the season for many anglers had been at slot or above. The appearance of aggressive, sub-slot bass along the south side suggests that the smaller class of fish may simply have been late to migrate north and are now showing up and spreading out into their summer haunts.
For surfcasters looking for a fun, active night on the water without the technical demands of matching tiny bait on the flats, the south side harbors and beaches deserve serious consideration right now. Ian's lighter rod approach — deliberately scaling down his tackle to make smaller fish more sporting — is a good mindset adjustment for this kind of fishing.
Weather Is Shaping the Bite
The Memorial Day weekend itself brought a notable weather swing. Earlier in the week, three consecutive days of 80-plus degree heat and full sun likely pushed water temperatures up by three to four degrees in the shallows. That kind of rapid warming can push fish off the flats and into less predictable behavior.
The holiday weekend then brought a sharp reversal — a north/northeast wind, cool temperatures, and cloud cover that felt more like early fall than late May. Counterintuitively, Ian welcomed it. Cooler air temperatures will slow the warming of the water, which helps prolong the skinny-water fishing season. If the water gets too warm too quickly, stripers abandon the flats and the shallower coastal zones earlier than normal. A cool week could buy anglers an extra week or two of that productive, accessible flats fishing before the summer pattern sets in.
For the holiday weekend specifically, Ian was hoping the cloud cover would help spark a daytime bite that sunshine typically shuts down. Overcast conditions reduce light penetration, which makes stripers more willing to stay shallow and active throughout the day rather than retreating to deep water until dusk.
Tide and Time
One consistent thread through Ian's report was the importance of tide and light alignment. He described a productive four-day run where a favorable dusk bite corresponded nicely with the tidal stage around that time of evening. That correspondence had since shifted, with an outgoing tide at dusk making his preferred locations a bit less productive at that particular hour.
His general advice: mornings and evenings remain the prime windows for shore anglers, particularly if sun and bright conditions are a factor. When the tide aligns with low light, the bite can be exceptional. When it doesn't, adjusting location — closer to the canal, for example, where current does more of the work — can compensate for a less-than-ideal tidal stage.
For the Canal itself, Ian made a Friday morning visit and found it productive and less crowded than he expected given the strong reports that had been coming out of that stretch of water. The canal has been acting as a superhighway connecting the bay fishery and fish moving through it have been creating some of the more dramatic surface feeds reported on the Cape this spring.
For anglers heading down Cape, the Goose Hummock in Orleans is stocked with everything you need across multiple fisheries. Clams, sea worms, and eels are all on hand so get out there and enjoy this long holiday weekend!
Tight Lines, Take Care, & Happy Memorial Day!🎣
