The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for this stretch.
To be straight with you, the next couple of weeks are looking pretty grim for a proper paddle. We’ve got a long stretch of small, weak swell and a lot of onshore or cross-shore wind messing things up. There is no real standout session in the whole run, so we’re playing a waiting game.
The only spot in the mix is Castles, a sandbar set-up that’s fairly consistent but rated as beginner-friendly. It's fairly exposed and likes swell from the SE.
The forecast kicks off with some surf on offer, but it’s not much to write home about. Thursday afternoon the 27th has a small 2ft swell from the ESE at 9 seconds, but a cross-on wind from the south at 12 mph has it chopped up. Combined wave energy is weak at 80.
Friday morning the 28th shapes up as the best of a bad lot. We’ve got that same 2ft SE swell, but the wind goes glassy – a light WNW at 3 mph. That’ll clean it right up, but the waves will still be very ordinary. The water temp is 76°, a touch warmer than normal for this time of year.
After that, it falls away fast. From Friday afternoon right through to Saturday the 5th of September, you’re looking at surf under 2ft, mostly with poor conditions and choppy faces. That’s a long gap of over a week with nothing worth suiting up for.
Things try to pick up a little around Sunday the 6th of September, with the swell bumping up to 5ft from the east, but the period is a short and mushy 6 seconds, and it’s cross-onshore again. That’s more of a mess than a wave.
Into the second week, we see a bit more energy on Monday the 7th of September – a 3ft ENE swell with clean conditions and light offshore winds from the NNE. It’s surfable, but still ordinary. Then on Tuesday the 8th, the swell period jumps to 13 seconds from the SE, which is a proper groundswell, but the wave height is only 2ft and the east-northeast wind is cranking at 16 mph. The combined energy is strong at 228, but the wind will ruin it.
Wednesday the 9th of September has a similar story: 2ft SE swell at 12 seconds, with light offshore winds from the north-northeast in the morning. Clean conditions, but the wave size is just too small to get excited about.
Friday the 11th of September morning sees glassy conditions again with a 2ft SE swell at 11 seconds. Clean as a whistle, but still just small, poor surf.
Honestly, there isn’t one true standout in this 16-day window. The closest we get to a decent session is Friday morning the 28th of August if you’re desperate for a glide on a clean, tiny wave. For anything with real push and shape, you’re going to have to wait.
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.
