The Lowdown
Alright, Rusty here, let's break down what's coming at Castles over the next couple of weeks.
To be honest, it's looking pretty bleak for a long stretch. From the 28th of August all the way through to the morning of the 9th of September, that's about 12 days of basically flat, messy conditions. The water is at 77°F, which is a touch warmer than normal for the season, so at least it's pleasant when you're just sitting out there.
We get a couple of mornings, on the 7th and the 8th of September, with glassy conditions—the wind goes light and variable, and even dead calm on the 8th morning. But the swell is tiny, around 2ft to 3ft, and from the S or SSW, so there's just no power. The combined wave energy is very weak, sitting between 29 and 55, so nothing to ride.
The first real sign of life comes on the morning of Wednesday, September 9th. The wind is light from the NNW, almost offshore for Castles, and a new swell rolls in from the SSE at about 3ft. The period is a long 14 seconds, which is proper groundswell, and the combined energy hits 347, which is moderate. Conditions look clean. This is your standout moment after all that flatness. It's not big, but a clean 3ft wave with that kind of period on a sandbar is what we've been waiting for.
By the afternoon of the 9th, that swell really fills in, hitting around 6ft from the SSE with a 13-second period, and the wave energy skyrockets to 1397, which is a strong pulse. The wind goes cross-shore from the SSW, which is not ideal, but there's some size there. That afternoon is your best shot at something with proper push, though it might be a bit much for the break and the conditions are marginal.
Then on Thursday morning, the 10th of September, we get clean offshore wind from the WNW with a 3ft SE swell at 11 seconds, and a moderate energy reading of 292. That’s another solid window, but the wind will likely shift onshore later in the day.
The following weekend, the 12th and 13th, the wind stays fresh and offshore, but the swell drops right back to about 2ft. The main windows to circle are the mornings of the 9th and 10th of September, but at this range, those long-period swells can be a bit unreliable, and the long period might make the sandbar a bit tricky.
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.
