The Lowdown

Alright folks, Rusty here. Let's have a look at what's cookin' for Diamond Beach over the next couple of weeks. It's a bit of a quiet stretch, so we're going to be patient.

Right off the bat, the first ten days or so are pretty bleak. We've got a lot of signals showing "poor surf conditions," and honestly, the wave heights are barely a bump. The first week and a half is a write-off for any real surfing. You'll see some tiny 1ft to 2ft slop, but with poor energy readings (42, 27, 13 – all weak) and mixed winds, it's just not worth paddling out. The swell direction from the SE is constantly fighting with onshore and cross-shore breezes. It’s a tough stretch.

Now, things might start to get a little interesting as we move into the second week. Keep an eye on the 6th of September. We finally get a glimmer of something. On the Sunday morning and afternoon, the wind swings offshore from the west, and we're looking at 2ft of groundswell coming from the east with an 11-second period. The combined energy hits 64 (moderate), and the conditions are described as clean. It's a tiny wave, but for a beginner, it might just be fun. The energy is still low, but with that offshore wind, it's the best looking window we have.

Then, moving into Monday, the 7th of September, the morning shows a fresh offshore breeze from the northwest, with the same 2ft of east swell at 11 seconds. The energy is 71 (still moderate). The wave state is "fresh offshore and clean," which is a beautiful thing to hear. It's still a small wave, but for a spot like Diamond Beach that's exposed to the SE, getting a consistent east swell with clean northwest winds is a rare treat. It's not a big day, but for the patient surfer, it’s the cleanest, most rideable option on the table across the entire forecast.

So, to sum it up: the first half of the window is a bust. You're better off doing something else. If you're itching for a surf, target the 6th and 7th of September. The surf is small, but it will be clean. The 7th has the best wind, so if I had to pick one, that's your best bet. Beyond that, the conditions get a bit messy again in the second week, with short-period windswell and onshore winds making a return. It’s not looking like a classic run, but at least we have a couple of windows to work with.

Stay patient, and keep your eyes on the horizon.

Information about the Diamond Beach Surf forecast

The above surf forecast table for Diamond Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Diamond Beach can be found by selecting the local surf guide option on the grey menu. Our Diamond Beach 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 (Diamond Beach) 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 Diamond Beach 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.

Diamond Beach is 43 km (27 miles) from Ocean City. If you plan a vacation in New Jersey, look for hotels and other accommodation in Ocean City. Ocean City has rooms for a wide range of budgets as well as car hire and transport links.
