The Lowdown
Alright, listen up. I’m not gonna lie to you, the next couple of weeks are looking pretty grim for a proper surf. We’ve got a long stretch of small, junky, wind-blown slop ahead before things finally start to show a bit of life.
The only spot on the radar is Castles, a sandbar setup that’s fairly consistent but is going to be struggling with the conditions for a while. The water temp is sitting right around average for this time of year, so nothing weird there.
We’re looking at a real dry spell from now until about the 16th. For over a week, the swell is tiny, the period is short, and the winds are mostly cross or onshore, messing up whatever small waves there are. The energy is weak, with values in the 40s to 90s, and the surf forecast is just poor. You’d be fighting chop for knee-high slop. Not worth it.
There’s a slight tease on the 11th and 12th with some cleaner, cross-offshore conditions, but the swell is still too small to get excited about. A couple of mornings with light winds and glassy conditions pop up, like on the 14th, but again, the swell is practically flat, coming in at 1ft with barely any energy (18).
Now, the second week starts to get more interesting. Around the 16th and 17th, we finally see some size start to build. The swell direction shifts to the east and the energy starts climbing into the 100s and 200s. By the 17th, we’re looking at 5ft of east swell, and the energy is at 200. It’s still not clean, with cross-onshore winds, but there’s finally some power.
The pick of the bunch looks like the morning of the 19th. The swell has settled to 2ft from the east, but the period has stretched out to 8 seconds, and more importantly, it’s glassy. Light winds from the south will have it looking clean. The energy is at a moderate 88. It’s not a classic, but it’s the only time in the whole window where the conditions truly line up for a surfable wave. It’s labeled as "surfable waves but very ordinary conditions," which tells you everything.
After that, it looks like the wind picks up again and the quality drops right back off. So, to be honest, if you’re desperate, that Wednesday the 19th is your one shot. It won’t be epic, but it will be clean. The rest of the time, you might be better off finding another hobby.

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.
