The Lowdown
Alright, let’s get this out. Rusty here, and I’ve got a surf outlook for you.
It’s pretty slim pickings here at Castles. The whole 16-day forecast has a big dry spell to start, with no real surf worth paddling out for until Sunday the 19th, and even then, it’s just barely enough to get wet. This is a classic case of the region being in a lull, and don’t hold your breath for a sudden epic run.
The first real chance comes on Sunday morning, the 19th of July. There’s a 4ft south swell rolling in, with a period of 7 seconds. The wind is offshore from the NNW, which is a major plus—it’ll keep the surface clean. It’s a sandbar break, fairly consistent, so you’ll get a few waves, but the energy is weak (combined energy of 160). The south swell direction is a decent match for the break’s optimum. This is a beginner-friendly sized wave, but the crowd factor is *sometimes*, so you might have a few others out there. It’s not a standout, more of a "better than nothing" session.
Sunday afternoon cleans up further with a lighter offshore wind, but the swell drops to 3ft. It’s surfable, but nothing to write home about.
The only real standout in the whole outlook is on Wednesday, the 22nd of July. The morning is a no-go—strong winds and a messy 7ft south swell (combined energy of 987) making it poor. But the afternoon is where it’s at. The wind swings offshore from the WNW, and the swell drops to 5ft with a period of 8 seconds. That’s a solid, clean wave for a more experienced surfer. The combined energy is moderate (331), and the offshore wind will make it glassy. The size is pushing into the “too big for beginners” zone, so it’s better suited for intermediate to advanced crew. This is the best on offer—a solid Wednesday afternoon session.
After that, it’s a slow fade. The morning of Saturday the 25th of July sees a 5ft ENE swell, but the period is a short 6 seconds, and the water is glassy, giving it a clean look, but the energy is moderate (207). It’s surfable, but the short period means the waves will be a bit weak and closey. The rest of the 16 days are just a mix of poor conditions, cross-shore winds, and weak energy, with nothing worth planning a trip around. The water temperature anomaly is about average for the time of year, so don’t expect anything unusual on that front.
Overall, Wednesday afternoon is the only real standout. The rest is a long, quiet stretch. Don’t bet the farm on it.
Rusty.

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.
