Alright, I’ve looked at what’s coming our way for the next couple of weeks, and I’ve gotta be straight with you. It’s a quiet stretch, no doubt about it. There’s a long gap here with barely a ripple to get excited about, so patience is the name of the game.

The first real chance of anything worth paddling out for doesn’t show up until Monday, July 13th. Before that, from now right through to the end of Sunday, July 12th, it’s a whole lot of nothing. Small, weak swells, poor winds, and just messy conditions. There’s a little pulse of energy showing on Wednesday, July 8th, with some combination swell energy hitting 146 (moderate) and waves around 4 ft from the south, but the wind is cross-onshore and choppy. Not worth your time.

Now, let’s talk about that Monday, July 13th. Castles is the only spot in the game, a sandbar break that’s fairly exposed to swell. It’s a beginner-friendly wave, and it’s fairly consistent. On the Monday morning, we’ve got a clean, offshore wind out of the northwest, light at 6 mph. That’s a proper offshore, and it’ll clean things right up. Swell is around 4 ft from the east, with a short period of 6 seconds, and the combined energy is a moderate 106. The water temp is a balmy 74°, which is 5° above normal for this time of year – that’s a standout, much warmer than you’d expect. It’s surfable, but the conditions are described as very ordinary, so keep expectations in check. It’s a small, weak groundswell, nothing to write home about, but with that clean wind, at least you’ll get a few fun ones. Crowds are sometimes an issue here, so don’t expect to have it to yourself.

That’s really the only bright spot. After that Monday morning, the wind goes, the swell drops, and we’re back to small, chopped-out junk. There’s a bigger pulse of south swell showing up on Friday, July 17th (6 ft, period 6 seconds, energy 203 – moderate), but the wind is howling onshore at 19 mph. That’s a mess. Saturday the 18th looks a bit cleaner with a cross-offshore wind and a 5 ft south swell, energy 252 (moderate), but it’s still just ordinary, not really a standout.

Honestly, if you’re desperate for a paddle, make the most of that Monday morning at Castles. Otherwise, it’s a waiting game. The long-range stuff on the 18th is promising if the wind plays ball, but it’s a week and a half away, so don’t bank on it yet. It’s one of those periods where the ocean just doesn’t have much to offer. Forecasts can always change, but right now, it’s a quiet spell.

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.
