The Lowdown

Alright, it’s been a quiet stretch, but there’s a glimmer of life creeping into the forecast. Let’s get into it.
Mate, it’s been flat and pretty dismal for a while. We’ve had a long dry spell with nothing worth paddling out for until the tail end of the week. The surf has been small, weak, and messy with cross-shore winds and lumpy chop. But things start to turn around from Monday morning, July 20th. That’s our first real shot at a wave.
Now, the spot we’re looking at is Castles (a sandbar break). It’s fairly exposed to swell and works best when the swell is coming from the southeast. The water temp is about average for this time of year, so nothing unusual there.
Monday morning, July 20th is our standout. We’ve got a clean, 4ft south swell creeping in with a 9-second period. The combined swell energy is reading a moderate 186, and with a light breeze from the north, conditions are clean. This is the best on offer in the whole forecast. The crowds show up here sometimes, so you might have a few mates out, but it’s not going to be a circus. The swell direction is SSE, which isn’t the absolute optimum SE, but it’s close enough to wrap in and give you something fun to push into. The waves will be small and clean – good for a beginner on a foamie or anyone who just needs to get wet.
The afternoon on Monday goes a bit cross-onshore from the ESE, so the morning is the clear window.
From there, we go back into a slump. Tuesday July 21st through Thursday July 23rd morning is mostly small, weak, and choppy. But then Thursday July 23rd sees a big jump in size – 8ft to 8ft from the east – but it’s accompanied by strong cross-onshore winds and a very high combined swell energy (521-752). That’s a lot of power, but it’s messy, lumpy, and only for experts if anyone’s keen on a battle. For most of us, it’s a kite-surfing day, not a paddle day.
The rest of the month, through to the 29th, is a mix of moderate swell with cross-shore winds and onshore chop, never really coming together cleanly again. There are some mornings with cross-off winds and decent sized swell, like Sunday the 26th, but the period is short and the conditions are lumpy.
So, to sum it up: your one true standout is Monday morning, July 20th at Castles. It’s clean, small, and surfable. After that, it’s a gamble with wind and mess. Get it while it’s good.

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.
