Delaware City, DE Daily Water Report — August 28, 2026

It’s a big-kite day—almost glass. The Delaware City water today is an easy, forgiving sheet under a full moon that pulled a classic solunar swing. Flat water dominates from dawn through dusk, making this a topshelf morning for kayaking and boating, each scoring in the low eights. The representative wind is a mild 5 knots out of the north-northeast, occasionally nudging to 7, and the wave height sits at zero—literally no measurable chop, swell, or wind waves. This is the flattest open water you’ll find without a puddle. Fishing grabs a 7.6, helped by that full moon and a pair of solunar windows: the major from shortly after noon into early afternoon, and a minor that syncs neatly with evening low tide. The incoming tide tops 1.72 meters just after noon, pushing water up the flats, and the outgoing ebb, bottoming 0.17 meters near 18:47, will concentrate bait-holding structure. Pressure is rising slowly from 1014 to 1018, a steady signal that often nudges fish into a late-feed mode. For divers, the score is the same 7.6 as yesterday, limited more by the flat conditions—zero wave action means zero current turnover—but the marine surface temp sits at a balmy 26.8°C. Visibility through the air is 14.7 kilometers, but that says nothing about underwater clarity; you’d have to check the spot. Surfing is a 4.5, as it has been for the past week, because there is simply no swell—not a single meter of wave energy on the charts. Sailing scores a 5.7, a step down from recent days; the breeze is light enough that you’ll be ghosting more than planing. Wildlife is a 6.8, a slight lift from yesterday, riding the low-tide exposure and the minor solunar spike near 18:34. Compare this to yesterday, when the wind was a fraction stronger and the scores nearly identical—today’s calm is just a hair more pronounced. Looking ahead, the marine forecast shows flatness persisting through the weekend, with winds creeping up to 10 knots by Saturday and Sunday. Monday and Tuesday bring a rising chance of showers, but still no swell. If you’ve got a paddle or a trolling motor, the window is today’s mid-morning ebb under a clearing sky.
