Marine Forecast for Aug 15–17, 2026
📋 Great Saturday, but Sun-Mon bring afternoon wind-wave chop
Excellent conditions all day with light 5-9knots ENE-NE winds and calm 1-1.2feet seas at 4-5 second periods. No bad windows - great day to be on the water.
Calm morning with light winds and small seas, but afternoon brings 13-14knots south winds with gusts to 24knots and steep, short-period wind-waves crossing the underlying swell. About 5 hours of choppy, confused seas in the late afternoon/evening - plan your trip around the morning calm.
Choppy, confused seas persist through midday with 12-15knots SE-SSE winds, gusts to 23knots, and steep 2-2.5feet short-period waves - roughly 6 hours of uncomfortable chop. Conditions improve substantially after 2:00 PM as winds and seas ease into the evening.
Saturday offers light winds and calm short-period seas ideal for boating, while Sunday and Monday see steady increases in south-southeast winds and choppy, short-period wind-waves during afternoon hours that create uncomfortable, bumpy conditions. Confidence is high overall, though wave period forecasts show some model disagreement, especially Saturday and Sunday.

About Sandy Hook
Sandy Hook is the northern gateway to the Jersey Shore — a six-mile barrier spit at the entrance to Lower New York Bay, with the Atlantic on one side, Sandy Hook Bay and Raritan Bay on the other, and some of the busiest recreational water in the Northeast in between. It is also the name boaters know from the NOAA zone forecast — the coastal waters from Sandy Hook to Manasquan Inlet — which is why the Hook is the reference point for anyone deciding whether to run the oceanfront or stay inside the bay.
The outlook below updates every morning from the latest marine model data, and each day gets an honest GO, CAUTION, or NO-GO call — the same AI rating used in the SeaLegs AI app.
Reading conditions at Sandy Hook
The water around the Hook changes character fast. The tip is a tide rip: current pouring in and out of New York Harbor meets ocean swell over shoal water, and an ebb tide against an onshore wind stands seas up steep and close right where small boats round the point. A forecast that reads manageable for the open beachfront can still mean a rough, wet ride at the rips and across the shoals toward the shipping channels — so weight the wave period as heavily as the height, and time the tip for slack water when the wind is up.
The Hook also gives you an out that pure oceanfront ports don't have: when the Atlantic side is a NO-GO, Sandy Hook Bay and Raritan Bay often stay fishable in everything but a hard north or northeast blow. Use the three-day view above to make that call — run the ocean on the day the window stays open, and work the bay side when it doesn't.
