Charleston, SC Daily Water Report — August 26, 2026

Today in Charleston, SC, it's a stellar day to hit the water for most activities, particularly boating and diving. With diving scoring a solid 8.2 and boating at 8.5, the conditions are ripe for underwater exploration and smooth sailing. The sea state is relatively calm, with wave heights hovering around 0.34 meters and the calmest conditions expected around 9:00 AM. The water temperature is a warm 30.2°C, slightly above the usual, making it inviting for both divers and swimmers. While the fishing score dips slightly to 7.2, it's still a decent day for casting a line, especially during the solunar major period from 9:53 to 11:53 AM. The waxing gibbous moon, nearly full, might add a bit of magic to your catch, though the tidal swings are moderate with highs and lows throughout the day. Sailing enthusiasts might find today slightly less thrilling with a score of 6.6, as the winds are relatively gentle, peaking at 11.9 knots with gusts up to 16.5 knots around 10:00 AM. The northerly breeze could make for a relaxed sail rather than an adrenaline-pumping race. Surfing, however, takes a backseat today with a score of 4.6, as the waves are not offering much in terms of height or power. The swell is modest at 0.24 meters, and the short period won't excite those looking for thrilling rides. Looking ahead, the weather remains generally favorable with rising temperatures and moderate winds, though rain chances increase toward the weekend. The best bet for today? Enjoy a peaceful morning paddle or a dive beneath the waves—the conditions are just right for a serene escape.
