The Lowdown
G’day, Rusty here. Look, I’m not gonna sugarcoat it – this is a pretty flat stretch ahead. Over the next 16 days, we’ve got a long, quiet run at Castles, and it’s really just a few moments where you might scrape a wave, but nothing that’ll get the heart pumping. There’s a gap of several days with no real recommendations from the start, and the whole period is a struggle for any decent surf.
The first bit of interest creeps in on Friday, September 4th. The morning shows a light 2ft swell from the south, period of just 7 seconds – short period stuff, low energy (97). But what makes it worth a mention is the wind: a light offshore from the northwest, keeping things clean. The water temp is about average for this time of year, nothing wild. It’s a sandbar break (Castles), and it’s fairly consistent, so there might be a few little waves for a beginner. But the combined energy is weak, so don’t expect much push. The afternoon cleans up even more with a gentle offshore, but the swell drops to 2ft. A total glass-off on Saturday afternoon, September 5th, with a tiny 2ft swell from the NE and glassy wind – it’s pretty, but the period is only 5 seconds, so it’s just small, weak lumps.
From there, things go downhill fast. The rest of the week into the second week is a constant run of poor surf conditions. The swell stays small, mostly 1ft to 2ft, and the winds turn cross, cross-onshore, or just too strong. On Monday, September 7th, a moderate breeze from the NE kicks up a cross-chop on a 3ft swell, but it’s messy. Later in the week, around Wednesday, September 9th, the wind picks up to 19 mph with a risk of thunderstorms – that’s fresh and lumpy, not for paddling. The combined energy readings are mostly two-digit numbers, under 100, showing just how weak and unappealing it is.
The last few days, from around Friday, September 11th through to Tuesday, September 15th, see the swell stay at 1ft to 2ft, with occasional offshore or cross-off winds that keep the surface clean, but the energy is still low (41 to 55). It’s a sandbar, so it takes a bit of swell to work, and we just don’t have it. This spot is fairly consistent, so usually you’d get something, but this run is a real dud. For the crew after something more than a knee-high ripple, it’s looking more like a kite-surfing setup than a paddle session.
Best bet? The Friday morning (September 4th) and Saturday afternoon (September 5th) are the only times with clean conditions and any swell at all. But honestly, it’s marginal. Keep an eye out – forecasts can change.

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.
