CatchWindow fishing intelligence

Charleston, SC Daily Water Report — October 5, 2026

Charleston gets a clear green light for small-craft time today, with kayaking (8.6/10), diving (8.8/10), and boating (8.5/10) leading the card. This is a notably gentle marine day: waves run about 0.3–0.6 m, with the calmest water near 4 AM at 0.32 m, and a light northerly wind generally 2.7–7.3 knots. The catch is the weather overhead—cloud cover is complete, humidity is 96%, and light rain is forecast through early afternoon. Atmospheric visibility is around 8.4 km, which is useful for navigation but says nothing about underwater visibility. The most comfortable all-around window arrives after the morning rain window eases and before dusk, especially around the afternoon high tide at 4:28 PM. Water remains warm at 26.5 C, about 1.1 C above average, while the small 0.24 m southeast swell and nearly absent wind waves should keep the surface comparatively orderly. The ocean current is modest at roughly 0.11 m/s toward 117 degrees, but tide-driven flow can still matter around the 9:56 AM low and the late-afternoon high; give inlets, channels, and exposed shoreline access their usual respect. For anglers, the 6.2/10 score is serviceable rather than spectacular. The stronger solunar opportunity is 8:10–10:10 AM, overlapping the falling tide toward the morning low, with another major period from 8:10–10:10 PM. Stable pressure near 1017 hPa and light wind help, but rain and the lower fishing score temper the enthusiasm. Chlorophyll is reported high at 3.04 mg/m³, but that is not a fish forecast. Sailing earns a middling 5.7/10: smooth water is welcome, yet there simply is not much breeze to work with. The morning’s strongest gusts, up to 12.2 knots around 8 AM, may be brief and come with damp conditions. Compared with CatchWindow’s reconstructed recent ratings, diving holds steady at 8.8, while boating and kayaking are a touch below the exceptionally easy conditions logged over the past week. Wednesday looks a little lumpier, Thursday settles somewhat, and the weekend trend turns rougher, with waves building to 1.0–1.8 m and stronger winds. Best bet: launch after the rain fades, ride the afternoon high tide, and enjoy the kind of low-wave day that makes careful planning feel pleasantly unfair.
