CatchWindow fishing intelligence

Delaware City, DE Daily Water Report — August 23, 2026

Delaware City draws an easy, almost unruffled water day, and the scores rank it without much argument: boating leads at 8.9, kayaking and diving sit close behind, sailing and wildlife are solidly usable, fishing is only middling at 6.6, and surfing is the leftover at 4.5. Current conditions and the Open-Meteo forecast describe a light west wind near 6 knots, mostly holding under 9, with the day’s sharpest gust around 15 knots near 17:00. Air warms from about 20 C into the mid-20s, skies stay mostly open, and atmospheric visibility is long—useful on the surface, and not a stand-in for what you can see underwater. A rain window is listed from 02:00 to 03:00, but representative precipitation is effectively none. Pressure is 1012 hPa and rising. The marine forecast is blunt: wave and swell height stay at 0 meters, with a slack current near 0.2 m/s setting east. NOAA CoastWatch puts sea-surface temperature at 25.3 C, a tenth of a degree below average; the marine field reads a warmer 28 C. Chlorophyll is very high under bloom conditions, a water-column measurement only. NOAA tides do the scheduling. A 0.28 m low at 02:52 lifts to 1.49 m at 08:35, drops to 0.25 m at 14:43, then builds to the day’s larger 1.83 m high at 20:56, after the 18:50 sunset. Solunar majors wrap that morning high and the evening rise, which, with rising pressure and light wind, is the fair case for a 6.6 fishing score—better than yesterday’s 5.6, still not a headline. Boating improves from 8.1 on the same dry, flat, light-wind setup; kayaking holds near 7.8. Diving stays 7.6 on wind, waves, available clarity, and warm water. Sailing is a 7: enough breeze to move, not enough to lean on. Wildlife ticks up to 7 on solunar timing, the afternoon low, and the easy wind. Surfing cannot climb because there is no wave to score. Tradeoffs are small and specific: that late-afternoon gust, UV near 7, and a last high arriving after dark. Suitability is not a safety declaration. The marine forecast stays flat through the 29th. Temperatures build, winds stay mostly light, and rain chances jump on the 27th and 28th before easing. Best bet: take the boat on the morning rise and treat the 17:00 gust as the day’s only real wrinkle.
