Cape May, NJ Daily Water Report — August 28, 2026

You want to be on the water today if you can, but pick your window carefully. The overall ease is decent for diving, boating, and kayaking, but the wind schedule and a full moon tide punch have to be respected. This is not a dead-calm day like Tuesday, but it’s a clear improvement from yesterday’s stiffer breeze. The big draw for divers is water clarity that the models peg as favorable, combined with a water temperature of 24.9 degrees, which is nearly a full degree above seasonal average. That’s the highest diving score in over a week, and it comes with almost no wind wave energy, just a modest southeast swell under half a meter. If you’re heading out below the surface, target the hour after high tide at 09:22, when the flood has pushed the cleanest ocean water in. The incoming current will be manageable, and with that low wind, you won’t be fighting chop on the surface either. On the opposite side, the outgoing after the 15:15 low will be stronger, so time your exit accordingly. For boaters and kayakers, the morning is the better half. Winds start just over a knot at dawn and barely reach five by late morning. That representative east breeze at five knots is a straight-on shore wind, which keeps the ocean surface tidy—the calmest wave height of 0.42 meters comes near 19:00, but that’s also right as the evening high tide builds. If you want the flattest ride, get out from 08:00 to 11:00, when tide movement is moderate and wind hasn’t had time to stack any fetch. The afternoon sees an uptick in gusts that never exceed seven knots, but it’s the full moon tidal push that’ll make you work harder, especially around the evening high at 21:40. Keep an eye on that current; 1.9 meters per second is a solid pull near the inlet. Surfing remains middling. The swell period is short at 5.9 seconds, and the height barely reaches knee-high. It’s rideable for a log or a foil if you’re patient, but don’t expect any push. The full moon low at 15:15 might expose some sandbar shape, but the energy just isn’t there for a memorable session. Wildlife watchers will want to be out near the early morning minor solunar period at 06:31, or the low-tide window around 15:15. The chlorophyll reading is very high, which typically concentrates the food web, though today’s score is a step down from the excellent 8.0 we had just five days ago. The difference is the wind: Wednesday was notably lighter. Looking ahead, Friday and Saturday stay pleasant with similar wave heights and only a slight uptick in wind—fine for most activities. Sunday into Monday brings a chance of late-summer instability, and by Tuesday, we may see a noticeable jump in waves and a stronger southerly breeze. Today is your best shot at a clean dive in above-average water temp before the pattern shifts. Sunset is at 19:40, and with a full moon rising shortly after, the evening bite could be the sleeper move of the day.
