CatchWindow fishing intelligence

Philadelphia, PA Daily Water Report — August 28, 2026

Today is a near-flat, settled water day that hands the victory to small-craft operators and anyone who enjoys a calm surface. The suitability scores point decisively at kayaking at 9.7 and boating at 9.0, and for good reason: representative wind is a mere 1 knot from the north-northwest, gusting to 3, with the entire day’s range staying below 4 knots. Waves are measured at zero across the board—no swell, no wind wave, nothing but a placid surface from sunrise at 06:25 through sunset at 19:42. The best windows for paddling or a quiet powerboat cruise are virtually the whole daylight period, though the morning outgoing tide between low at 09:04 and the afternoon high at 14:35 may offer the most interesting current movement for those who like to work a little tide. The full moon, 100% illuminated, rises at 19:46 just after sunset, so an evening float under that big moon with no wind is a strong possibility—just mind the low at 21:12 if you’re near shallow ramps. Fishing scores a solid 7.3, boosted by the solunar major period from 12:02 to 14:02 and generally stable, rising pressure at 1016 hPa. The morning minor period from 06:32 to 07:32, coinciding with dawn and the final hour of the outgoing tide, is the other window worth noting. With 12.3 km of atmospheric visibility and no rain in the forecast, conditions are comfortable for a long session, though the 95% humidity and overcast sky (100% cloud cover) mean you’ll feel the dampness more than the temperature of 20.3°C would suggest. Surfing remains at 4.5, unchanged from the past week—zero wave height is zero wave height, and no amount of favorable wind can manufacture a ride. Sailing at 4.6 reflects the same calm: there simply isn’t enough breeze to fill a sail reliably, though a drifter in a lightweight dinghy might find the faintest zephyrs in the open channel. Diving returns no score due to missing water temperature and clarity data, but the flat surface would be ideal for a mask if you knew visibility underwater—unfortunately, we can’t assess that today. Compared to recent history, today’s calm is a slight improvement over yesterday’s 3.7-knot breeze, and it matches the best conditions from earlier in the week (August 26 and 25 both saw low wind and near-identical boating scores). The key difference is the full moon and its associated tide range, which is the largest of the past several days. Looking ahead, Thursday stays equally flat with no waves and light wind, but temperatures climb into the mid-20s. Friday brings a chance of afternoon showers and a stronger breeze near 8.5 knots, still manageable for most. The weekend into next week trends hotter—pushing past 30°C by Saturday—with increasing chances of rain and occasional gusts above 10 knots by Monday and Tuesday. The flat water won’t last forever. Best bet today: launch a kayak on the outgoing tide this morning and let the moonrise be your turn-around beacon.
