The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer over the next couple of weeks.
Right off the bat, we’re looking at a pretty flat spell. There’s no real surf to speak of until the afternoon of Tuesday the 21st of July. That’s a solid week of nothing worth paddling out for. The wait is on.
The first real glimmer of hope comes Tuesday afternoon at Castles. The swell is a clean 5 feet out of the south, with a period of 8 seconds. The wind is light and cross-offshore, which is a good sign. The combined wave energy is moderate (303). This is a sandbar break, and with the swell being a touch over 5 feet, it’s not for beginners, but it’s a solid mid-range option for the rest of us. Tuesday afternoon is the best-looking window in the first week.
The rest of that week is a write-off—a mix of onshore winds, smaller swell, and choppy conditions. You’ll be fighting the wind more than the wave.
Now, the real standout of the whole outlook is Sunday the 26th of July. The morning session at Castles looks excellent. We’re looking at a 6 ft south swell, period 7 seconds—not a groundswell, but a punchy windswell. The wind is offshore from the WNW at 9 mph, and the energy is strong (511). That’s your best bet by a long shot. The water is about average for the time of year, so no surprises there. Expect clean, lined-up waves. The crowd is sometimes an issue here, so for a session this good, you’ll want to be early.
The following Monday and Tuesday mornings (27th & 28th July) are still surfable, with 4 ft to 3 ft, clean conditions, and light winds, but the energy is more moderate (254 and 173). They’re a decent follow-up, but not a patch on the Sunday glory.
After that, the forecast gets messy again. The end of the run is just wind and chop.
So, to sum it up: the first week is a total dud. The second week has a single, clear standout on Sunday the 26th of July. That’s your day. Circle it.
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.
