CatchWindow fishing intelligence

Lewes, DE Daily Water Report — August 28, 2026

Today is a solidly decent day on the water, but not a standout one. The most dependable bet is kayaking and boating, both scoring in the high 6s to low 7s, thanks to the light southeast wind holding steady around 3 knots and barely gusting. Those conditions translate to flat, manageable conditions on the Delaware side, especially during the late-morning high tide at 9:28 and the early-afternoon low at 3:20. The wave height is a uniform 0.44 meters from a 112-degree swell, with almost no wind-wave component, so the chop is minimal. Fishing scores a 6.5, which is a step down from yesterday’s 7.1 and the 6.9 from a couple days ago; the solunar major periods around midnight and noon offer some theoretical edge, but the full moon and overcast sky may not be working in your favor. Surfing is a middling 5.7, reflecting the long-period swell that’s just under seven seconds and the light wind that won’t groom the faces into anything special. Diving data is missing today, so we can’t speak to underwater visibility, but the marine surface temp is a balmy 25.7 degrees—warmer than the recent 24.8 and 22.2 readings from earlier in the week. A few tradeoffs to keep in mind: the humidity is high at 91 percent, and the cloud cover is total at 100 percent, so it will feel sticky and dim despite the mild air temp around 22-27 degrees. Visibility is good at over 12 kilometers, but don’t confuse that with underwater clarity. The rising barometer and zero rain chance mean stable weather, but the strong ocean current at 1.8 meters per second toward 323 degrees could be a factor for small craft near the bay mouth. Compared to yesterday’s 10.5-knot wind and today’s 5.3-knot peak, the coastal edge is calmer and more inviting for paddling and fishing from a boat. Looking ahead, Friday will see waves staying in the same range while wind picks up to nearly 12 knots, pulling kayaking and boating scores down. Saturday and Sunday offer a brief sweet spot with waves dropping to 0.2-0.3 meters and lighter wind, making the weekend the better choice for flat-water fun. As the new week heats up toward 37 degrees by Wednesday, the sea breeze will strengthen again. For today, the best-bet sentence is this: glide through the midday slack on a kayak before the afternoon breeze stirs the surface.
