There's something genuinely special about a summer morning on Long Island Sound. The air is warm, the harbor is coming alive, and by the time you clear Port Jefferson and the open water opens up ahead of you, whatever was on your mind when you left the house has already started to fade. Long island summer fishing has that effect on people — and out here on the Sound, aboard a 70- or 80-foot boat out of Port Jefferson Harbor, it looks like this: a light chop on the water, porgies coming over the rail, sea bass hitting the bottom rigs, and a crew that keeps everything moving so you can just enjoy the ride.

What Long Island Summer Fishing Actually Looks Like
Summer fishing on the Sound has its own personality — and once you understand it, you'll love it. The big porgy spawning run that lights up May and early June has settled by July, and fluke push to deeper water as surface temperatures climb. What fills in behind it is excellent: bottom fishing comes fully into its own. Deeper drops, rock piles, and wrecks become productive, sea bass show up in force, and jumbo porgies are very much in the mix all summer long.
I've seen groups come aboard in July and leave with a cooler full of porgies and sea bass and huge smiles on their faces. The fish don't read the calendar. Summer bottom fishing on Long Island Sound is genuinely good fishing — it just looks a little different than what you get in May, and knowing that going in makes all the difference.
What also makes summer special is everything around the fishing. The weather is warm and comfortable. The Sound is usually calm enough that people who are a little nervous about being on the water find themselves completely relaxed within the first twenty minutes. Families spread out along the rails. First-timers watch the crew get everything set up and realize this is far more approachable than they imagined. And when the mates clean the catch at the end of the trip — that moment when a bag of fresh fillets comes together right in front of you — there's always someone who looks genuinely amazed. That happens on summer trips just as much as it does in spring.
If you want to see what a typical day on one of our boats looks like from dock to fillet, here's what a day on the water in Port Jefferson really looks like.
What's Biting — The Summer Species Lineup
This is the question we hear most often, so let's walk right through it.
Porgies (Scup) Porgies are the backbone of summer bottom fishing on Long Island Sound, full stop. They're present all season, they bite reliably, they fight harder than their size suggests, and they're absolutely delicious on the table. For families and first-timers, porgies are just about perfect — there's usually enough action to keep everyone engaged, and the jumbo ones give experienced anglers something to get excited about too. If you've been wondering whether long island summer fishing is worth it, porgies alone answer that question with a yes.
Sea Bass (Black Sea Bass) As summer progresses, black sea bass become an increasingly important part of the picture. We fish them on wreck and bottom trips out of Port Jefferson, and they put up a great fight. Our crew stays current on all New York DEC regulations for sea bass — size limits, bag limits, all of it — so you don't have to think about any of that for a second. Just fish.
Fluke Fluke are typically available into July and can be excellent in the right conditions. As water temperatures rise and baitfish move off the shoals, fluke push to deeper water and become harder to target consistently. Our fishing reports are updated regularly and are a great way to see exactly what's happening before you book.
Bluefish Bluefish arrive later in the season — late summer is when they typically start showing up in force out of Port Jefferson Harbor, and they are genuinely exciting on the rod. Strong, aggressive, hard-running fish. When the blues are around, it adds a whole different energy to a day on the Sound.
Striped Bass Striped bass make appearances throughout the season. We run special trips for them when conditions and tides line up right — it's always worth asking what's happening when you call to book. We'll tell you exactly what's going on out there.
Why Long Island Sound Is a Great Place to Fish in Summer
There's something worth understanding about where we fish. Long Island Sound — the North Shore of Long Island — has a different character than the ocean side. The Sound tends to be calmer and more sheltered, and that typically makes for a gentler, more comfortable experience on the water. For families with kids, for first-timers, for anyone who's a little unsure about how they'll feel on a boat — that matters enormously.
We run two vessels out of Port Jefferson Marina at 118 West Broadway: Celtic Quest IV, a 70-foot open boat with rod storage throughout, and Celtic Grace, our 80-foot fishing yacht with full cabin accommodations, men's and women's restrooms, and heating for shoulder-season trips. Both boats are stable, comfortable platforms for a summer day on the water — the size makes a real difference in how people feel out there.
Twenty-five years of fishing Long Island Sound out of Port Jefferson also means something. Captain Des and the crew know these waters — the seasonal movements, the depth changes as summer progresses (we can be fishing up to 100 feet of water by late summer), the spots that consistently produce. That local knowledge is what you get with a family-owned operation that's been right here since 2001.
The Sound is also genuinely beautiful. Heading out of Port Jefferson Harbor into the open water, with the North Shore on one side and Connecticut faintly visible on a clear day — there's a reason people fall in love with fishing here. It's not just about what's on the end of the line.
What a Day on the Water Out of Port Jefferson Feels Like
You arrive at 118 West Broadway, Port Jefferson — right in the heart of the village, steps from the marina. The boats are there, the crew is already set up, and the whole thing feels a lot more relaxed than you might expect. We recommend arriving about 45 minutes early, especially in summer when the village is busy and parking takes a few minutes to sort out. Our directions page has everything you need, and we'll send you full details when you book.
Once you're aboard, the crew gets everyone sorted — rods, bait, a quick rundown of what to do. If you've never held a fishing rod before, that's completely fine. Our mates love teaching people, and there's no pressure whatsoever.
The ride out to the fishing grounds takes anywhere from 30 minutes to an hour, depending on where we're headed. In summer, we're often fishing deeper water out in Smithtown Bay or farther along the Sound. When you get there, the fishing begins — and time passes faster than you'd think. Four hours on a half-day trip genuinely flies by. At the end, the mates clean your fish right on the boat. You go home with bags of fresh fillets, and more often than not, someone in the group becomes the unexpected hero of the cookout.
After the trip, Port Jefferson village is right there. The Steam Room has been serving anglers since 1977. There are restaurants and shops all along the waterfront and Main Street. It makes for a complete day out, especially if you're coming in from New York City or from farther out on Long Island.
Open Boat or Private Charter — Summer Works for Both
We run two types of trips, and summer is a great time for either one.
Open boat trips are our daily public fishing trips — you book your spot, show up, and fish alongside other people who had the same idea. It's a lively, social experience, especially in summer when the boats are full of families, birthday groups, and first-timers all sharing the rail.
Private charters are available for groups who want the boat to themselves — corporate outings, bachelor parties, family reunions, birthday celebrations, and plenty more. Our crew takes care of the whole day, and you get to set the pace. If you're planning a summer group event, here's a look at how open boat and private charter trips compare — worth a read before you call.
Summer charters are popular, and with good reason. The weather cooperates, the atmosphere on the water is wonderful, and groups who've never done anything like this together tend to have a genuinely memorable time. I've seen corporate groups who spend their days behind screens completely unwind the moment the boat clears the harbor. Something about the open water, the shared experience, the friendly competition over who catches the biggest fish — it brings people together in a way that's hard to replicate anywhere else.
Captain's Tip: Timing Your Summer Trip
A few things worth keeping in mind when you're planning:
- Late May through mid-June is peak season — the porgy run is at its strongest, fluke fishing is excellent, the weather is beautiful, and the energy on the water is high. If you have flexibility, this is the window to target.
- July is wonderful for the overall experience. Warm days, full boats, that unmistakable summer feeling. Fishing moderates a little compared to June, but the day on the water is fantastic.
- August into September is when late-season fishing picks up again. Bluefish start appearing out on the Sound, sea bass fishing is strong, and the fall run is building. September can produce some of the best days of the entire year.
- Weekdays are generally less crowded than weekends — and often more affordable too. If your schedule allows it, a midweek trip in summer has a relaxed, unhurried feel that's hard to beat.
Check our fishing reports before you book — we update them regularly and they'll tell you exactly what's been happening on the water.
Frequently Asked Questions
What fish can I catch on Long Island Sound in the summer?
The main summer species out of Port Jefferson are porgies (scup), black sea bass, and fluke into July. As the season moves toward August, bluefish typically begin showing up, and striped bass are always a possibility depending on conditions. Bottom fishing is the heart of the long island summer fishing experience on the Sound — and it delivers.
Is summer a good time to go fishing on Long Island?
Absolutely. Long island summer fishing is a little different from the spring peak — the big porgy spawning run has settled, and fluke push to deeper water as temperatures rise — but the fishing is genuinely enjoyable and the overall experience is wonderful. Sea bass become a bigger part of the picture, porgies are around all season long, and summer is when families and groups tend to be most available. It's a natural time to plan a trip.
Do I need any experience to go on a summer fishing charter?
None at all. Our crew takes care of everything — baiting your hook, showing you how to hold the rod, explaining what to do when you feel a bite. We've had people catch their first fish ever on summer trips out of Port Jefferson, and watching that happen never gets old. If you've never been fishing before, you're in exactly the right hands.
What's included in a summer fishing trip with Celtic Quest?
Everything. Fishing rods, all tackle, all bait, your New York fishing license, expert crew guidance throughout the trip, and fish cleaning and filleting by our mates at the end. You bring yourself, sunscreen, food and drinks (beer and wine are welcome aboard), and comfortable clothes. That's really all you need. You can find more details on our trips page.
How far offshore do you fish in the summer?
Typically between one and five miles offshore, though the depth of water increases as summer progresses — we can be in up to 100 feet of water by late summer as fish move to deeper structure. Travel time to the fishing grounds from Port Jefferson Harbor is generally 30 minutes to an hour depending on where the bite is.
Can I bring my family — including young kids — on a summer fishing trip?
Yes, and summer is one of the best times to do it. We recommend children be at least five years old, and child rates apply through age 12. The Sound tends to be calmer than the ocean, which makes a big difference for kids and for nervous adults too. Our crew is experienced with families and genuinely loves introducing young anglers to fishing for the first time. For more on bringing the whole family, here's a look at family fishing trips on Long Island Sound.
What's the difference between a half-day and full-day summer fishing trip?
Half-day trips run four hours and are the most popular option for families and first-timers — you get a full, satisfying fishing experience without an all-day commitment. Full-day trips run longer and cover more water, which can mean more variety in what you encounter. Both formats are available in summer depending on trip type and location. If you're not sure which is right for your group, this breakdown of half-day vs. full-day trips is a great place to start.
Ready to Book Your Summer Day?
Summer on Long Island Sound is one of those experiences that's hard to fully describe until you've lived it. Warm air, open water, porgies and sea bass coming over the rail, a crew that genuinely loves what they do — and then a bag of fresh fillets to take home at the end of the day. It's a full day. A good one.
