The Lowdown
G’day, Rusty here.
Alright, let’s be straight up—looking at the next 16 days at Castles, there’s really nothing to get excited about. The first recommendation doesn’t even pop up until Monday the 17th of August, so you’ve got a dead weekend ahead. After that, the whole period is a struggle. From Monday the 17th until Wednesday the 26th of August, it’s a long, drawn-out run of poor to barely surfable conditions with gaps of days where it's just not worth paddling out.
Saturday the 15th and Sunday the 16th are total write-offs. Tiny swell, cross-onshore winds, choppy and messy—leave the board in the car.
Monday the 17th of August is the first sniff of anything. We’ve got a small south swell pushing 5ft, but the period is short at 7 seconds, so it won’t have much punch. The combined swell energy is weak at (205) so it’s marginal. The wind swings offshore from the NW in the afternoon, so the morning is cleaner with a cross-offshore breeze. The water temp is about average for this time of year. It’s beginner-friendly size, but honestly, the quality is ordinary.
Tuesday the 18th and Wednesday the 19th drop back to tiny waves—2ft and 2ft—with poor wind and chop. Not worth it.
Thursday the 20th and Friday the 21st see a little more swell at 4ft, but the wind is cross-shore and choppy. The energy is weak to moderate (98) and the period is short. Surfable if you’re desperate, but you won’t be stoked.
Saturday the 22nd of August is small again, around 3ft to 4ft from the east, but cross-shore winds keep it messy. The same story runs into Sunday the 23rd.
Monday the 24th of August gives a tiny glassy moment in the morning with 1ft swell from the SE and a 12 second period—longer period groundswell, but so small it’s barely a ripple. The energy is weak (66). It’s clean, but you’ll be scratching for waves.
Tuesday the 25th is clean but tiny, 1ft.
The only faint glimmer in the whole run is Wednesday the 26th of August morning. We get a glassy 4ft south swell with a 6-second period—short period but clean. Combined swell energy is moderate (132). The wind is glassy, so it’ll be clean. Still, the swell is weak and short period, so it’s for beginners or people happy to bob around. It’s not a standout.
The rest of the 26th onward into the 27th and 28th stays small, with a bit of cross-offshore wind on the 27th morning cleaning up a 2ft SE swell with an 11-second period (moderate energy at 153), but it’s still tiny.
Honestly mate, there’s no true standout in this 16-day window. The best call is the Wednesday the 26th morning for the glassy conditions, but don’t expect pumping waves. It’s a quiet run for Castles.
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.
