The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for our local stretch of coast.

Straight up, it’s a pretty quiet start. We’ve got a solid week of tiny, messy conditions ahead with nothing worth paddling out for. Don't bother waxing up until at least the 20th of September. There's a long gap of nothing from now until then, so save your energy.

The first sign of life shows up on Sunday the 20th of September. A little pulse of 4ft swell from the NE rolls in during the afternoon, and we get a clean offshore breeze from the NNW. The water’s sitting at a balmy 77°, which is much warmer than normal for this time of year – you’ll feel that difference straight away. The combined energy is moderate at 118, but don’t get too excited. It’s surfable, but it’s not a standout by any means. It's just a little tease.

The real window to watch starts on the 24th of September, Thursday morning. We see a jump in size with 5ft swell from the ENE and clean, cross-off wind from the West. The energy cranks up to 313 – that’s a solid, moderate push. This is the first real chance for a decent wave, and conditions look clean.

But the best of the whole run looks to be Friday the 25th of September, morning session at Castles. The swell sits at 4ft from the East with a period of 9 seconds, and we get a clean offshore wind from the WNW. The combined energy is strong at 293, meaning there’s some proper grunt in the water. This is the one to circle on the calendar. It’s going to be a touch big for beginners at over 4ft, but for the rest of you, that’s a cracking morning. The swell direction from the East lines up nicely with what this sandbar likes. Just keep an eye out for crowds – they’re *sometimes* around here.

The Friday afternoon sees a stronger 30 km/h offshore from the NW, which might make things a bit skittish. After that, the weekend fades back into smaller, clean but ordinary surf, so get your fix on Friday morning if you can.

For the rest of the second week, it’s a slow fade-out with smaller, cleaner waves but nothing that’ll blow you away.

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.
