G’day, Rusty here. Let’s talk about Diamond Beach. Over the next couple of weeks, it’s a bit of a tough stretch for anything that’ll get your blood pumping. The wave energy is weak for the most part, and the winds are rarely working in our favour. There’s a long gap of nothing worth paddling out for.

The first real flicker of hope doesn’t show up until Sunday, July 19. The swell is tiny at 3ft, straight from the SSE, with a period of 9 seconds—that’s a bit of short-period groundswell, but it’s got some energy behind it (combined energy 134). The wind is a cross-offshore from the WSW at 9 mph, which keeps the surface clean. It’s surfable, but it’s very ordinary. The break is exposed and inconsistent, so you’ll be waiting around for the sets. Crowds are possible here. The water temperature is about average for the time of year.

Before that, the whole stretch from July 5 right through to July 18 is a write-off. The swell is tiny—mostly 0.7ft to 3ft—with periods all over the place, often under 8 seconds, and the wind is mostly cross or cross-onshore, lumping up the surface. On Saturday, July 11, there’s a glassy morning with the wind from the north at 3 mph, but the swell is only 2ft and weak (combined energy 58). It’s a calm, clean paddle but there’s barely a wave to ride. Not worth the wetsuit.

The only other day that sniffs of anything is Monday, July 13, when the swell bumps up to 5ft from the east with an 8-second period and moderate energy (226). But the wind is cross-shore from the NE at 12 mph, making it choppy and messy. Still, if you’re desperate and don’t mind a fight, that’s the biggest swell of the window, but it’s not clean.

Overall, the standout is Sunday, July 19 morning. It’s not a classic, but it’s the only session where you’ll get a few workable ones under clean skies. Beyond that, the forecasts can change, but don’t hold your breath.

Rusty.

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.
