The Lowdown
Alright, Rusty here. Let’s have a look at what Diamond Beach has in store for us over the next couple of weeks.
Honestly, I’m not gonna sugarcoat it – it’s a pretty grim run. The first week is near enough a write-off with barely a ripple worth paddling for. We start off Wednesday 22nd July with a weak 3ft south swell, but the wind is a messy cross-off from the WSW at 15 mph and there’s a risk of thunderstorms. Combined wave energy is only 134 (moderate), but the quality data says it’s poor. That sums it up. Through the rest of the week, the swell drops off fast – down to 1ft by Friday, and the wind keeps swinging around onshore or cross-shore, making a mess of things. Not a single standout in that first week, just flat or near-flat conditions with weak slop.
We’re looking at a gap of about 10 days of nothing decent until we get a tiny blip on Sunday 2nd August. That morning, we see a 3ft SSE swell with a period of 8 seconds and clean conditions thanks to a light cross-off breeze from the WNW at 9 mph. The combined energy bumps up to 74 (still weak), and the report says “surfable waves but very ordinary conditions.” That’s the only whole-hearted recommendation in the whole window, so it counts as the best on offer – but don’t get too hyped. It’s about the smallest surf you’d bother getting wet for, and the swell direction (SSE) isn’t ideal for Diamond Beach, which wants SE. After that morning, it quickly fades back to nothing.
Water temp this morning is 75°, which is about 1° above normal – so pretty average for the time of year, nothing unusual there.
Because the swell never gets over 5ft, the whole period is fine for beginners if there was any decent wave, but there just isn’t. The break is inconsistent, and with the poor swell and messy winds most days, a kite would have more fun than a surfboard on most of these afternoons.
So there you have it, one barely average morning on Sunday 2nd August, and the rest is a long, flat gap. The forecasts might change, but right now, I’d leave the board in the car.

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.
