CatchWindow fishing intelligence

Charleston, SC Daily Water Report — October 6, 2026

Charleston gets a solid-but-not-sleepy water day: boating is the best all-around call at 7.4/10, with sailing close behind at 7.1 and diving leading the activity scores at 8.6. The catch is a persistent NNE breeze around 9 knots, with gusts capable of reaching the low 20s, so this is a day for competent plans rather than casual autopilot. The most useful window is early, before the day’s stronger gust potential builds and while seas are nearest their overnight low. Wave height bottoms around 0.52 m near midnight, then runs roughly 0.5 to 1.2 m through the day. The representative sea state is 0.72 m at a short 4.25-second period, including 0.56 m wind waves at 2.8 seconds. That short-period chop can make an otherwise modest forecast feel busier, especially for smaller craft and paddlers. Kayaking still rates 6.6/10, but yesterday’s much lighter 3.9-knot wind supported an 8.6; conditions have plainly become more workmanlike. For anglers, the 6.2/10 fishing score is middling rather than miserable. The late-morning solunar major period, 9:02 to 11:02 AM, overlaps the approach to the 11:01 AM low tide, giving it the day’s clearest timing case. A second major period runs 9:02 to 11:02 PM, close to the 11:46 PM low. Pressure is falling from around 1017 hPa, while no rain is indicated. Keep expectations practical: the score accounts for timing, tide, pressure, wind, and available clarity data, not guarantees. Divers have the strongest numerical outlook, helped by warm 26.1 C marine SST and manageable waves, though surface chop and gusts still deserve respect. The forecast’s 14.4 km atmospheric visibility is useful for travel and navigation, not a promise about underwater visibility. Cloud cover is complete, UV is zero, and the air stays cool-to-mild at 17.2 to 23.3 C. Wednesday through Friday look broadly favorable, with waves mostly 0.5 to 1.0 m and light peak winds near 9 to 11 knots; Saturday turns less inviting with higher seas, stronger wind, and a 61% rain chance. Best bet: make the late-morning tide change your anchor, but keep a firm hand on anything that catches the NNE gusts.
