Duck, NC Daily Water Report — August 28, 2026

The diving is the clear standout today, earning an 8.6 out of 10, and for good reason. A southwest breeze around 9 knots with gusts only touching 11 keeps surface chop manageable, while the ocean swell runs a modest 0.34 meters from the east at a 7.9-second period. Combined with a marine surface temperature of 27.1°C, which sits more than a degree above the long-term average, the underwater conditions are as inviting as they’ve been all week. If you’re planning to get in the water, the calmest wave heights are forecast to dip to 0.36 meters near 19:00, but the mid-morning hours around the 08:14 high tide offer the best light and current cooperation for divers. For those staying topside, sailing and boating post solid scores of 7.6 and 7.0 respectively. The 3.2 to 14 knot wind range provides enough push for a decent sail, though the full cloud cover and 100% humidity make it feel heavier than the 25.5°C air temperature suggests. A rain window is possible from 19:00 to 22:00, so plan an early return if you don’t want a wet ride home. Compared to yesterday, when boating scored a 7.2 and sailing a 6.9, today’s slightly steadier breeze edges the sailing experience upward, though it’s not the crisp 9.2 from August 25. Fishing lands at 6.9, a fair grade given the solunar minor periods this morning from 06:35 to 07:35 and this evening from 18:35 to 19:35, both coinciding with tide changes. The high chlorophyll reading of 2.94 mg/m³ often signals rich water, though that’s not a guarantee of fish activity—just a piece of the puzzle. The outgoing tide after the 14:13 low might stir things up, but the full moon’s pull on currents can make midday feeding windows unpredictable. Surfing sits at 6.2, a slight drop from yesterday’s 6.6, as the 0.48-meter wave height with a short 6.25-second period won’t thrill anyone chasing steep faces. Kayakers face a 5.7 score, a significant step down from the 8.5 they saw two days ago, thanks to the building breeze and that persistent ocean current running 0.7 m/s toward the north-northeast. The coming days offer a mixed bag. Friday and Saturday look similar, with wave heights holding under 0.4 meters and winds staying below 11 knots, making for a repeat of decent diving and manageable boating. By Sunday into the start of September, the wind ramps up past 14 knots, and wave heights push toward 0.7 meters, which will improve surf prospects but complicate small-craft outings. Best bet: If you’re not already in the water by the time the afternoon breeze picks up, you’ve missed the best of today’s glassy window just above the horizon.
