The Lowdown
Alright, let’s get into it.
First up, we’ve got a real quiet spell on our hands here. The first week or so is basically a write-off – tiny, weak, messy conditions that won’t get you out of bed. We’re looking at a stretch from Monday the 24th of August right through to the end of the month where the swell is small and the wind is all over the shop, mostly cross or onshore. You’ll see some glassy conditions on the Wednesday morning the 26th, but with only 1ft of 9-second SE swell (combined energy of just 24), that’s not enough to push you around. It’s a long wait.
The first real glimmer of hope isn’t until Monday the 31st of August. That afternoon, we see a sneaky little 1ft SE groundswell with a very long 18-second period rolling in. The wind shifts to a light offshore from the NNW, and the combined energy bumps up to 121 (moderate). It’s still small, but that long period will give it some shape. The crowd factor is listed as "sometimes" here at Castles, so you might get a few others with the same idea, but for a small wave day it shouldn't be too hectic. The water temp is sitting at 77°, which is much warmer than normal for this time of year, so that’s a bonus.
Honestly though, the standout action doesn’t kick off until Thursday the 3rd of September. That’s when things get serious. On the Thursday morning, we’ve got a solid 8ft swell from the east, but the period is a short 7 seconds. The combined energy jumps right up to 937 (strong). That’s a lot of water moving. The wind is a cross-off from the NNE, keeping things clean. That 8ft is right on the limit – it’s only for experienced surfers at that size, especially with a short period making it punchy. The Friday the 4th keeps that energy going with 8ft from the ENE and a bit longer period of 8 seconds, energy hitting 1191 (very strong), and still clean with a north wind. The Saturday the 5th drops slightly to a consistent 7ft from the east, still with offshore winds.
If you’re picking the absolute best, I’d lock in Saturday the 5th of September. The swell is a solid 7ft from the east, period of 8 seconds, energy of 671 (strong), and you’ve got clean cross-off winds from the NNW in the morning. It’s a big, powerful day, but the wind makes it workable. The wave comment says "marginal surf forecast or questionable tide conditions," which can happen with short-period east swell at a sandbar, but the clean wind is the selling point. That's a proper day out for the crew who can handle it.
From Sunday the 6th onward, it starts to back off. That Sunday morning still has 5ft from the east with light cross-off winds, but it’s dropping. A couple more days of small, clean leftovers follow before we taper off into nothing again.
So, bottom line: wait it out through the end of August. The 31st is a tiny but clean taste. The real deal is from the 3rd to the 5th of September, with Saturday the 5th being your best shot at a proper clean, powerful session. After that, it fades.

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.
