August is one of the hottest months of the year along South Carolina’s Grand Strand—but don’t let the summer heat fool you. While anglers may have to adjust their strategy, August continues to offer excellent opportunities for both nearshore and offshore fishing in Murrells Inlet and Myrtle Beach.
Warm water temperatures mean fish behavior changes compared to the spring and fall seasons. Some species head deeper in search of cooler water, while others remain active around reefs, wrecks, bait schools, and offshore structures. For anglers willing to fish early in the morning or head offshore, August can produce some unforgettable catches.
At Myrtle Beach Sport Fishing, August remains a favorite month for visitors enjoying a Myrtle Beach vacation. Families, first-time anglers, and experienced fishermen alike can enjoy productive days on the water while experiencing everything the South Carolina coast has to offer.
Here’s what you can expect during August 2026.
What Makes August Fishing Different?
By August, ocean temperatures off Murrells Inlet typically reach their highest point of the year. Warmer water affects both fish behavior and feeding patterns.
Instead of feeding aggressively throughout the day, many species become most active:
- Early in the morning
- Late in the afternoon
- Around changing tides
- Near schools of baitfish
- In deeper, cooler water offshore
This doesn’t mean the fishing is slow—it simply means experienced captains adjust where and how they fish to stay on productive bites. King mackerel may move deeper during the hottest part of the day, while offshore species like mahi-mahi continue to thrive in warm Gulf Stream waters.
Top Fish to Target in August
King Mackerel (Kingfish)
August continues to be a productive month for king mackerel.
These fast, hard-fighting fish remain one of the most popular targets on Murrells Inlet fishing charters.
Best Conditions
- Early morning
- Around bait schools
- Near reefs and artificial structures
- Live bait or slow trolling
As surface temperatures climb throughout the day, kingfish often move deeper, making downriggers or planers effective tools for staying on the bite.
Difficulty: ★★★★☆
Mahi-Mahi
If you’re heading offshore, August is still an excellent month to target mahi-mahi.
These colorful fish are famous for:
- Incredible jumps
- Fast runs
- Bright neon colors
- Outstanding table fare
Mahi often gather around:
- Floating debris
- Weed lines
- Temperature breaks
- Offshore current edges
Every offshore trip has the potential to produce exciting mahi action.
Difficulty: ★★★★☆
Amberjack
August is prime time for anglers looking for a true workout.
Amberjack continue holding around offshore reefs and wrecks.
These powerful fish are nicknamed “reef donkeys” because of their unbelievable strength.
Don’t be surprised if you need a short break after landing one.
Difficulty: ★★★★★
Grouper
Bottom fishing remains productive during August.
Depending on regulations and conditions, anglers may target several grouper species around:
- Offshore ledges
- Natural bottom
- Artificial reefs
- Deep structures
Once hooked, grouper immediately try to return to cover, making them one of the strongest fish you’ll encounter.
Snapper
August continues to provide opportunities for offshore bottom fishing.
Depending on current regulations and seasonal openings, anglers may encounter various snapper species while fishing deeper reefs and wrecks. Always check current federal and state regulations, as seasons and harvest rules can change.
Spanish Mackerel
Spanish mackerel remain active throughout August.
Although schools can be unpredictable from day to day, they frequently feed aggressively near the surface around schools of baitfish.
Spanish mackerel are excellent targets for:
- Families
- Children
- First-time anglers
Their fast strikes and exciting fights make them one of the most entertaining fish in local waters.
Black Sea Bass
Depending on regulations and open seasons, black sea bass continue to provide excellent bottom fishing opportunities.
They’re ideal for anglers looking to:
- Catch dinner
- Experience consistent action
- Introduce children to fishing
Always verify current harvest regulations before your trip, as management rules may change annually.
What About Cobia?
By August, the spring cobia migration has largely moved north.
While it’s still possible to encounter cobia, anglers should view them as a bonus rather than the primary target.
If catching cobia is at the top of your bucket list, late April through early June generally provides the best opportunities in Murrells Inlet.
Best Time of Day to Fish in August
Because August temperatures climb quickly, timing matters.
Early Morning
★★★★★
The first few hours after sunrise often produce the most consistent action.
Fish are actively feeding before the midday heat.
Midday
★★★☆☆
Fishing can slow somewhat as water temperatures rise.
Experienced captains often adjust by:
- Fishing deeper
- Moving offshore
- Targeting structure
- Following bait schools
Late Afternoon
★★★★☆
As temperatures begin to ease, many species become active again.
Evening trips can provide excellent opportunities during late summer.
Weather Conditions in August
August typically brings:
- Warm air temperatures
- Warm ocean water
- Afternoon thunderstorms
- Light morning winds
- Calm offshore conditions on many days
While afternoon storms are common during the South Carolina summer, experienced charter captains closely monitor weather and prioritize safety. Trips may be adjusted or rescheduled if conditions become unsafe.
Wildlife You Might See
Fishing isn’t the only attraction.
August is also an excellent month for wildlife viewing.
Guests frequently spot:
- Atlantic bottlenose dolphins
- Brown pelicans
- Ospreys
- Flying fish
- Sea turtles
- Various seabirds
Many families say these wildlife encounters become just as memorable as the fish they catch.
Is August Good for Families?
Absolutely.
Families visiting Myrtle Beach often worry that August heat will make fishing difficult.
Fortunately, most charters begin early enough to take advantage of cooler morning temperatures.
Children especially enjoy:
- Catching Spanish mackerel
- Reeling in black sea bass

Fishing charters remain one of the highest-rated family activities during a Murrells Inlet vacation.
