If you are planning a trip to the Grand Strand, you have probably asked, “what fish can I expect to catch in August in North Myrtle Beach?” before locking in a date. In short, what fish can I expect to catch in August in North Myrtle Beach is a mix of inshore, nearshore, and offshore species, including red drum, flounder, Spanish mackerel, king mackerel, sharks, and Gulf Stream game fish such as mahi-mahi. Therefore, the right answer really depends on whether you fish the backwater creeks, the nearshore beachfront, or the deep blue water of the Gulf Stream.
Key Takeaways: August fishing North Myrtle Beach commonly yields inshore red drum, nearshore Spanish mackerel, and offshore mahi-mahi.
- ▸Inshore August trips commonly produce red drum (spottail bass), flounder, speckled trout, sheepshead, and black drum.
- ▸Nearshore charters frequently find Spanish mackerel, king mackerel, tarpon, and several shark species feeding along the beach.
- ▸Offshore and Gulf Stream trips can reach mahi-mahi, wahoo, snapper, grouper, and occasionally sailfish, depending on sea conditions.
- ▸Nearshore Atlantic water off the Carolina coast often runs in the mid-to-upper 80s°F in August, per NOAA buoy data, which pushes bait and gamefish into predictable patterns.
- ▸Because every charter is private, captains build the plan around your group rather than a fixed itinerary.
What Fish Can I Expect to Catch in August in North Myrtle Beach?
August fishing in North Myrtle Beach typically produces red drum, flounder, and speckled trout inshore; Spanish mackerel, king mackerel, tarpon, and sharks nearshore; and mahi-mahi, wahoo, snapper, and grouper offshore in the Gulf Stream. Specific results vary day to day because licensed captains adjust each trip around tides, water temperature, and bait movement. As a result, no single species is guaranteed on any charter, and a good captain will have a backup plan ready.
Specifically, August sits at the peak of South Carolina’s warm-water season. Baitfish schools like menhaden, or “pogies” as locals call them, pull predators like king mackerel and sharks close to the beach. Meanwhile, deeper offshore structure holds snapper and grouper that stay active even in the summer heat. For a day-by-day look at recent trends, our North Myrtle Beach fishing report and our dedicated breakdown of what types of fish you can catch in August both track these seasonal shifts in more detail.
Inshore Fishing in August: Red Drum, Flounder, Trout, and More
Inshore trips stay inside the protected creeks, marshes, and the Intracoastal Waterway, where water temperatures and current are easier to manage. In August, red drum, also called spottail bass or channel bass, school heavily around oyster beds and grass lines. Flounder tend to hold on sandy bottoms near creek mouths, ambushing bait as the tide moves. Speckled trout, meanwhile, often bite best early in the morning before the water warms.
In addition, these backwater and inland waterways stay calmer than open water, which makes them a strong choice for families, children, and first-time anglers. Captains who fish these creeks year-round know which bends hold fish on a given tide stage. For a closer look at how local guides read these patterns, see our Myrtle Beach inshore fishing report for August.
Sheepshead and Black Drum Near Structure
Sheepshead, sometimes nicknamed the “convict fish” for their black-and-white stripes, gather around dock pilings, jetty rocks, and bridge structure in August. Black drum behave similarly, holding tight to hard structure where fiddler crabs and barnacles collect. Because both species feed by crushing shellfish rather than chasing bait, patient bottom fishing with small hooks usually outperforms fast-moving lures.
Nearshore August Runs: Spanish Mackerel, King Mackerel, and Sharks
Nearshore charters fish within a few miles of the beach, close enough to see the shoreline but far enough to find faster-moving baitfish schools. Spanish mackerel run hard in August, often slashing through pogy schools near the surface. King mackerel, their larger cousin, typically hold a bit deeper and respond well to live bait trolled slowly along nearshore structure.
Similarly, shark fishing picks up as water temperatures climb. Blacktip and spinner sharks are common nearshore targets, and tarpon occasionally roll through the same baitfish schools. For anglers curious about how these nearshore species compare to inshore and offshore catches, our guide on what fish you can catch near Myrtle Beach breaks it down by location. The South Carolina Department of Natural Resources also tracks regional catch data and seasonal regulations through its official SCDNR site.
Offshore and Gulf Stream Fishing in August
Offshore and deep-sea trips run well beyond sight of land, reaching wrecks, ledges, and eventually the warm current known as the Gulf Stream, a powerful Atlantic current that carries tropical water north along the coast. Because this current brings warm, clear blue water close to the Carolinas in summer, August is one of the better months to target true pelagic gamefish.
Mahi-Mahi, Wahoo, and Bottom Species
Mahi-mahi, also called dolphinfish, gather under floating weed lines and debris in the Gulf Stream, often in aggressive feeding packs. Wahoo, known for blistering speed, tend to hold near temperature breaks and drop-offs. Below the surface, vermillion snapper and grouper remain active on bottom structure, though federal regulations control which species and sizes may be kept at any given time. NOAA Fisheries publishes current offshore species rules and closures through its official NOAA Fisheries site, and a licensed captain will confirm what applies on the day of your trip.
How Water Temperature Shapes August Fish Behavior
Water temperature drives almost every decision a captain makes in August. NOAA coastal buoy readings near the Carolina coast commonly show nearshore surface temperatures in the mid-to-upper 80s°F during peak summer, which pushes some species into deeper, cooler water during the hottest part of the day. Consequently, many captains start trips early in the morning, when surface temperatures are lower and fish are more actively feeding.
In contrast, baitfish often stay shallow and concentrated, which is exactly why predators like Spanish mackerel and sharks move in close to shore. Above all, tides matter just as much as temperature. A moving tide stirs bait and triggers feeding, while a dead-slack tide can shut the bite down almost entirely, regardless of species.
How to Choose the Right August Charter Trip
Because August offers so many options, picking the right trip type matters more than picking a specific species. Follow these steps to narrow down the right charter for your group.
- Decide on your target depth. Choose between calm inshore creeks, a nearshore run along the beach, or a longer offshore trip into the Gulf Stream based on how much open water your group wants to handle.
- Match the boat and trip length to your group. Families with young children usually do better on shorter inshore trips, while experienced anglers chasing mahi-mahi or wahoo should plan for a full-day offshore run.
- Confirm timing around tides and weather. Ask your captain which tide stage and time of day historically produce the best results for the species your group most wants to target.
- Book early during peak summer. August is a high-demand month along the Grand Strand, so securing a date through an online reservation well in advance helps avoid schedule conflicts.

“August is one of the most forgiving months out here. Bait is everywhere, and whether you’re six feet from the dock or sixty miles offshore in the Gulf Stream, something is usually willing to bite.” — Captain Keith Logan, founder, North Myrtle Beach Fishing Charters

Frequently Asked Questions About Fish to Catch in August in North Myrtle Beach
What fish can I expect to catch in August in North Myrtle Beach?
What fish can I expect to catch in August in North Myrtle Beach depends on the trip type, but common catches include red drum, flounder, Spanish mackerel, king mackerel, and Gulf Stream species like mahi-mahi and wahoo. Sharks and tarpon are also frequent nearshore catches during this month.
How hot does the water get in August near North Myrtle Beach?
Nearshore Atlantic water near the Grand Strand commonly reaches the mid-to-upper 80s°F in August, based on coastal buoy readings tracked by NOAA. This heat pushes baitfish and predators into specific depth zones, which is why timing matters for a strong bite.
Why do inshore and offshore trips produce different fish in August?
Inshore creeks and offshore Gulf Stream waters have completely different temperatures, salinity, and structure. Therefore, species like red drum and flounder thrive inshore, while mahi-mahi and wahoo need the warm, clear offshore current to survive and feed.
What is the difference between a nearshore and an offshore August fishing trip?
Nearshore trips stay within a few miles of the beach and target species like Spanish mackerel, king mackerel, and sharks. Offshore and Gulf Stream trips run much farther out, usually taking longer, in pursuit of mahi-mahi, wahoo, snapper, and grouper.
How much does an August fishing charter typically cost?
Pricing varies by trip length, boat size, and how far the trip travels, since inshore, nearshore, and offshore trips use different boats and fuel costs. The most accurate way to get a quote is to review current rates and trip options through the online reservation system before booking.
How long does a private August fishing charter last?
Inshore trips often run a few hours, which works well for families and shorter schedules. Offshore and Gulf Stream trips, in contrast, typically require a full day because of the longer travel time to reach productive water.
What common mistakes do anglers make on August trips?
A frequent mistake is booking the wrong trip type for the group’s comfort level, such as choosing a long offshore run for anglers prone to seasickness. Another common error is skipping sun protection and hydration, since August heat can affect a trip just as much as the fishing conditions.
What is the best time of day to fish in August?
Early morning trips generally perform best in August because water temperatures are lower and fish feed more actively before the midday heat sets in. That said, moving tides can still produce a strong bite later in the day, regardless of the hour.
Are August fishing charters suitable for beginners and children?
Yes, inshore and backwater trips are especially well suited to beginners, families, and children because the water stays calm and protected. Captains also provide hands-on instruction, which helps new anglers get comfortable quickly.
Do I need a fishing license for a charter in August?
No, required fishing licenses for charter guests are included with the trip. In addition, rods, reels, bait, tackle, and required onboard safety equipment are provided as part of a private charter.
What should I bring on an August fishing charter?
Sunscreen, sunglasses, light breathable clothing, and water or a cooler of drinks are strongly recommended given the August heat. Non-slip shoes are also helpful, since boat decks can get wet during the trip.
Are shark species caught in August dangerous to handle?
Blacktip and spinner sharks, the most common August catches nearshore, are handled carefully by the captain and crew using proper tools and techniques. Guests are not expected to handle sharks directly, which keeps the experience safe for the whole group.
How far offshore do Gulf Stream trips travel in August?
Gulf Stream trips typically travel well beyond nearshore waters to reach the warm current, often requiring a longer run time than inshore or nearshore trips. Exact distance depends on sea conditions and where the current sits on a given day.
In conclusion, what fish you can expect to catch in August in North Myrtle Beach really comes down to where you fish. Inshore creeks favor red drum, flounder, and trout, while nearshore waters bring Spanish mackerel, king mackerel, and sharks within reach. Offshore and Gulf Stream trips, meanwhile, open the door to mahi-mahi, wahoo, snapper, and grouper for anglers ready for a longer run. Because every trip at North Myrtle Beach Fishing Charters is private and planned around your group’s goals and comfort, a licensed captain can match the right depth and destination to the fish you most want to catch this August.
