Alright, Rusty again, givin' it to ya straight for Diamond Beach.
It's a dry spell, mate. We're lookin' at a long, flat, or just plain messy run for the next couple of weeks. The swell is barely a whisper for the first week, and when it does try to show a pulse of life, the wind or conditions just trash it. The water’s at a balmy 73° (Diamond Beach), which is a touch warmer than normal for this time of year, but that’s the only good news.
The first real chance of anything surfable doesn't turn up until Friday, July 10th. Saturday morning, July 11th, offers a slight glimmer with a clean 2ft of SSE swell, light NNW winds, but the energy is weak and it’s still pretty ordinary. That’s about as good as it gets for a while. Sunday, July 12th, the wind swings WSW and hits 19 mph for the afternoon, pushing a messy 4ft easterly swell – more of a wind-blown whitewash than a wave for a beginner. From there, it’s mostly small, onshore, and choppy through the middle of the month. We get a glassy moment on the morning of Wednesday, July 15th, with a tiny 3ft easterly pulse, but it's short-lived and gutless.
The standout? If you’re desperate for a paddle, Friday morning July 10th. It’s not much: a 3ft south-swell with clean conditions and a light cross-offshore breeze. The combined swell energy is weak. It’s surfable, but that's about all you can say. There’s no hidden gem here, just a waiting game. For a beginner spot that’s inconsistent and sometimes crowded, this blank run is pretty normal for the area. Honestly, for the second week (from July 14th onward), you’re better off finding something else to do—it’s tiny, onshore, and flat.
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.
