False albacore signal fall's arrival off Charleston Harbor

What's biting

What's next

Look for the harbor to keep shedding a few more degrees through the week as the fall shift continues; that kind of cooling typically sharpens surface activity from false albacore working bait pockets near the inlet and nearby structure. The swing tides around this full moon are worth building a trip around: fish the last two hours of the push toward the 8:43 AM high, or work the outgoing water toward the 3:08 PM low, when current concentrates bait against structure and edges. If the pattern holds, surface action should build through the weekend as temperatures settle into the mid-70s. Offshore, keep an eye out for the confirmed red snapper season dates, since the fall window is short and worth planning around once it's set.

Context

Late September in Charleston Harbor sits right at the seasonal turn: water still carrying summer warmth in the upper 70s but starting its slide toward the classic fall pattern. That shift typically pulls baitfish through the inlets earlier than the open Atlantic sees it, and draws surface predators like false albacore into range ahead of the deeper cold. A full moon this week adds extra tidal push, which is normal for the pattern and generally works in favor of current-driven bites rather than against them.
