Ship John Shoal, NJ Daily Water Report — August 27, 2026

Sailing takes the top spot today with an 8.2, and that’s the call for anyone looking to get out on Ship John Shoal. The SSE breeze is holding steady near 12 knots with gusts into the upper teens, which gives you consistent pressure without the kind of volatile shifts that spoil a good reach. Boating follows close at 7.2, still a solid afternoon on the water, though that building afternoon gust potential—nearly 27 knots around 18:00—means you’ll want to keep an eye on the clock and have a reef ready. Surfing at 4.3 is a non-starter by comparison. Waves are barely cracking 0.3 meters with a 2.6-second period, and what little energy exists is coming from a short-period swell out of the southeast, tangled up with light wind chop. That’s ankle-high and gutless. If you’re paddling, kayaking scores a 6.5, which is workable in the morning before the wind really ramps, but by midday the chop will have you fighting for every stroke. Diving lands at 7.6, buoyed by that warm surface temperature at nearly 27°C and a mild +0.6 anomaly, but the chlorophyll reading is very high—over 9 mg/m³—which means a green, soupy water column with visibility suffering accordingly. The bottom might be warm, but you won’t see much of it. Fishing at 6.6 is an honest middling score. The solunar window from 11:19 to 13:19 aligns with the day’s best potential, but the falling barometer and building afternoon wind will push fish deeper or shut down the bite entirely. The bloom conditions in the chlorophyll signal heavy plankton, which in turn draws bait, but without confirmed species or feeding activity, treat that as background noise rather than an invitation. Compared to recent days, today’s breeze is a step up from the light air of the 25th and 26th, when boating hit 8.6 and 9.3 respectively. That calm window has closed. The sailing score is the best since the 23rd, when an 8.6 came with similar wind but a higher pressure regime. Today’s falling pressure and building gusts borrow some of that same energy but add a touch of instability. Looking ahead, the next few days offer a dramatic cooldown in wind. Thursday drops to peak gusts around 11 knots with waves barely a ripple, and Friday through Sunday taper further, with Saturday and Sunday seeing peak winds under 9 knots. That’s prime flat-water boating and kayaking weather, but the sailing window shrinks fast. If you want to be heeled over, today is your day. Otherwise, wait for the glass.
