Alright folks, Rusty here with the outlook for Diamond Beach. I’m looking at the charts and, honestly, it’s a bit of a tough spell ahead.

Right off the bat, the water's sitting at a warm 75° with an anomaly of 4°, which is much warmer than normal for this time of year—nice for a session without a full wetsuit.

We've got a long quiet period ahead. There’s nothing worth paddling out for from Sunday the 5th right through to Saturday the 12th of July. The swell is tiny, the winds are mostly messy, and the energy is weak (combined energy values sitting in the teens and thirties). You'll be chasing ripples out there, and I wouldn't bother.

The first real glimmer comes on Monday the 13th. The morning session shows a bump in swell to 5ft from the ENE, with a clean cross-offshore breeze. The combined energy jumps up to moderate (180), but the period is a short 6 seconds—so it’s gonna be a bit lumpy and disorganised. Still, it’s the best we’ve seen, and for a beginner-friendly spot that’s inconsistent, it might be worth a look if you’re desperate. The winds will be clean, so the surface will be smooth, even if the waves aren't perfect.

After that, it’s a rinse-and-repeat of poor conditions. The swell tries to pick up again mid-week, but the 18th and 19th of July see winds turning onshore again, with stronger southerly winds making things choppy and blown out. The energy climbs back into the 140s and 160s, but it's not clean. The 20th of July morning shows a clean cross-offshore breeze returning with a tiny 2ft swell from the SSE, but it’s just not enough to get excited about.

To be honest, for this area, a long dry spell like this isn't unusual. The spot is inconsistent at the best of times, and these forecasts can flip. But right now, step away from the board and wait for a better window.

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.
