The Lowdown
Alright, let’s get straight into it. I’m looking at the charts for Castles, and I gotta be honest with you – this is a tough stretch. There’s barely a ripple worth paddling for over the next couple of weeks. We’ve got a long, flat spell ahead.
Right now, and for the next several days, it’s all small, weak, and messy. The water temperature here is sitting at 77°, which is a massive 6° warmer than usual for this time of year. That’s really unusual – it’s like the ocean forgot what season it is. But the surf? Almost non-existent.
We start off on Sunday the 6th with tiny 1 ft swell from the ENE, but the wind is a cross-shore breeze that’s putting a chop on it. The combined energy is a weak 28, and it’s just not worth getting wet. That trend holds through Monday and Tuesday – we get a couple of clean mornings with light offshore winds, but the swell is only 1.0 ft to 2 ft. Not enough to push a floaty down the line.
Wednesday the 9th sees a shift in wind, but it’s from the SW at 12-22 mph, cross or cross-on, and the swell is tiny and choppy. Still no go.
Thursday the 10th brings a bit more size – we see 6 ft from the SSW in the morning, and the combined energy jumps to 221 (moderate). But the wind is a cross-shore at 16 mph, and the period is a short 6 seconds. It’s going to be lumpy, sectiony, and pretty average. For a beginner-friendly sandbar like Castles, that’s not ideal. The afternoon drops back to 4 ft.
Friday the 11th has a clean window with a light cross-offshore wind and 3 ft from the south, but the energy is weak at 82. It’s rideable if you’re desperate, but nothing to write home about.
From there, it’s a long run of poor surf. Saturday the 12th through to Tuesday the 15th is mostly onshore wind, small swell, and choppy conditions. There’s a brief moment on Tuesday the 15th afternoon with a fresh offshore wind from the NNW and 3 ft swell, but the period is a short 5 seconds, so it’ll be weak and quick. Energy is only 80.
The rest of the second week is more of the same. We see glassy conditions on Saturday the 19th morning with 3 ft from the east, and the wind is dead calm – that’s the cleanest we’ll get. But the swell is tiny, period is 6 seconds, and combined energy is just 72. A few fun little rollers for a longboard maybe, but nothing with any push.
Honestly, there are no standout days here. The only one that even slightly catches the eye is Thursday the 10th for size, but the quality is poor. For the rest, it’s a waiting game. The forecasts can change, and it doesn’t tend to stay this quiet forever, but right now, it’s looking like a solid 16-day gap with no proper surf. Leave the board at home and go for a swim instead.

Information about the Castles Surf forecast
The above surf forecast table for Castles provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Castles can be found by selecting the local surf guide option on the grey menu. Our Castles surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Castles) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Castles may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Castles is 8 km (5 miles) from Atlantic City. If you plan a vacation in New Jersey, look for hotels and other accommodation in Atlantic City. Atlantic City has rooms for a wide range of budgets as well as car hire and transport links.
