Duck, NC Daily Water Report — August 23, 2026

Put the dive flag and the boat first. Duck is handing out one of those late-August days when the ocean stays small and the air stays dry, and the activity scores make the ranking plain: diving 8.5 and boating 8.2 lead, sailing 7.9 sits right behind, and the rest of the card is merely decent. Those numbers are a fit to the forecast, not a safety stamp. Open-Meteo has the air around 26 C, feeling closer to 30 in sticky 85 percent humidity, under a nearly empty sky—only 4 percent cloud and no rain window. Pressure is 1014 hPa and still rising after a day that bottoms near 1011. The representative breeze is an 8-knot east-northeasterly, gusting only to 9, though the day’s envelope runs about 4 to 15 knots and the sharpest gust, just over 20 knots, is timed at midnight. Marine seas stay modest: 0.4 to 0.6 meters, a 0.26-meter swell near 10 seconds from the east, and short wind chop on top. The calmest water arrives late, about 0.38 meters near 21:00. A half-meter-per-second current sets southeast. Marine SST is 27 C, 2.2 degrees above average, which helps the diving score along with this light wind and small sea. Atmospheric visibility is a clean 16 kilometers; that is air, not a claim about what you will see underwater. Fishing and kayaking both land at 6.6, surfing 6.4, wildlife 6.1. The swell is simply too small and the wind-wave period too short to chase a ride, and the fishing number is a middling blend of solunar timing, rising pressure, and that same light wind—not a fish count. Solunar majors run 07:06–09:06 and 19:06–21:06, with quieter minors around 01:36 and 13:36. A waxing gibbous moon, 76 percent lit, rises at 16:11. Tide data did not arrive, so leave the flats clock out of the plan. Yesterday’s reconstructed scores held diving and boating at the same high marks, but sailing was only 5.3 in a lighter 4-knot breeze, fishing a touch weaker, and kayaking and wildlife both stronger at 8. Today’s extra wind helps the sail and trims the paddle. The next few days stay small—waves mostly 0.3 to 0.5 meters through the 26th—then breeze and rain chances climb on the 27th and 28th. Best bet: take the boat or drop under today while the easterly stays polite and the sea is still sitting down.
