The Lowdown
Alright, I’m Rusty, and here’s how it’s looking for your local stretch.
Right off the bat, I gotta be straight with you—this forecast is a rough one for surfers. There’s a big gap of no real surf on offer for the first several days. The first time we see anything worth mentioning is Monday the 3rd of August, but even then, it’s a struggle.
We’re looking at Diamond Beach as the only spot in the mix. The pattern overall is weak small swell, poor surf conditions, and a lot of choppy, messy wind. For the first week, nearly every day is a write-off. The swell is tiny, period is short, and the wind is mostly cross-onshore, chopping it up. The water temperature is about average for the time of year, no real anomaly to speak of.
The only flicker of hope comes on Monday afternoon, August 3rd. The wind swings offshore from the NNW, cleaning things up nicely. The swell is a tiny 4 ft from the SSE, with a short period of 8 seconds. The combined energy is moderate (135). It’s surfable, but just barely—it’s strictly for beginners looking to get wet on a soft top. The wave quality is “very ordinary,” but at least it’s clean.
After that, it’s back to the grind. Tuesday the 4th through to the end of the first week is all small, weak, and messy. Cross-onshore winds, short periods, and energy readings mostly in the teens or low 20s. Not worth paddling out.
The second week doesn’t offer much hope either. Sunday morning, August 9th and Monday morning, August 10th are clear but small and weak, with cross-shore winds. Tuesday, August 11th sees a lighter cross-offshore breeze from the west, keeping things clean, but the swell is still only 2 ft from the SSE with a period of 7 seconds and weak energy (54). Again, only for total beginners.
There is a brief spike in energy on Sunday morning, August 16th with a combined energy of 142 (moderate), but the swell is 2 ft from the ENE with a 9-second period and the wind is a messy cross-onshore. The conditions are poor, so it’s another miss.
The honest truth is there’s no standout session in this 16-day window. The swell is too small, the period is too short, and the wind is rarely your friend. With Diamond Beach being exposed and inconsistent, this is a long, flat run. It’s one of those stretches where you might be better off fishing or checking the kite forecast if the wind picks up. The setup looks more interesting for kite surfing than paddle surfing on the days with stronger cross-onshore wind.
Hang in there—forecasts can change, and it doesn’t stay 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.
