Best Water Temperatures for Popular Inshore Saltwater Species
Water temperature is one of the biggest factors determining where fish feed, how active they are, and what patterns they’ll follow. While fish can be caught outside these ranges, these temperatures are generally considered prime conditions for Carolina inshore fishing.
| Species | Best Water Temperature |
| Southern Flounder | 65°–78°F |
| Red Drum (Redfish) | 65°–85°F |
| Spotted Seatrout | 60°–75°F |
| Black Drum | 60°–80°F |
| Sheepshead | 60°–75°F |
| Tarpon | 75°–88°F |
| Spanish Mackerel | 68°–82°F |
| Bluefish | 62°–75°F |
| Cobia | 68°–80°F |
| Tripletail | 75°–88°F |
What This Means in the Carolinas
When water temperatures reach the mid-60s in spring, redfish, trout, flounder, and black drum become increasingly active. Many anglers consider 68° to 72°F the sweet spot when multiple species are feeding aggressively.
When temperatures climb into the upper 70s and low 80s, redfish remain active, flounder are still feeding well, and summer species such as tarpon, cobia, and tripletail become more common.
Once water temperatures exceed about 85°F, many inshore species continue feeding, but they often shift their activity to early mornings, late evenings, and periods of stronger tidal movement when oxygen levels are higher.
The Magic Number
If a Carolina inshore angler could order a perfect water temperature, many would choose 72°F. At that temperature, flounder are feeding, trout are comfortable, redfish are active, baitfish are abundant, and nearly every major inshore gamefish is in a predictable pattern.
As many old Carolina guides will tell you, “Watch the water temperature before you watch the calendar,” because fish don’t know what month it is, but they always know how warm the water feels.
