The Lowdown

Alright, this is Rusty, and I’m looking at what’s on offer for the next couple of weeks. I gotta be straight with you – it’s a tough stretch. There’s a real lack of any decent push from the ocean, and the conditions are mostly working against us.

We’re looking at Diamond Beach as the only option in the whole 16-day window, and to be honest, it’s a real struggle. The water is sitting at 76°, which is a touch warmer than normal for this time of year, but that’s about the only upside.

The whole run starts with nothing. From Tuesday the 25th of August right through to the end of the month, we’re looking at tiny, weak swells. On Tuesday morning, we’ve got a 1ft SE swell with an 11-second period, but the combined energy is just a feeble 21, and it’s described as poor surf conditions. The wind is a cross-offshore, which is clean, but there’s just no power in the water. This pattern keeps up day after day. We get a bit of a bump on the 27th with a 3ft SSE swell that pushes the combined energy to 200 (moderate), but the wind is a messy cross-onshore at 15 mph, making it choppy and unrideable.

The first day that even registers a score of 1 out of 10 is Friday the 28th of August in the afternoon. We get a bump to 2ft from the south, but with a period of only 6 seconds, it’s just weak, short-period windslop. The wind is glassy, which is a major positive for clean surface, but the wave quality is described as "very ordinary conditions." It’s the best of a bad bunch, but that’s not saying much.

We go through another week of tiny, crummy surf. The end of the first week into September doesn’t offer any real hope. There’s a morning on the 1st of September with a beautiful, clean, gentle offshore wind from the WNW, but the swell is a pathetic 0.7ft from the ESE with a 15-second period. That long period suggests it’s groundswell, but there’s just no height to it. The energy is only 45. On the 2nd of September, we have a glassy morning with a 1ft SE swell and a 12-second period, giving a combined energy of 61, but it’s still just surfable, not good.

The whole run of the forecast is a flat spell. There are no standouts. The swell is too small and the wind is mostly onshore or cross-shore, making a mess of the tiny waves. For a beginner spot, this is just a write-off. For anyone else, it’s a hard pass. This kind of blank run isn’t unusual for a spot like Diamond Beach, which is already inconsistent. It’s a waiting game, but forecasts can change, and it tends not to stay this poor forever.

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.
