The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this 16-day window for Diamond Beach is a tough one to call. We’re looking at a long stretch of nothing much, with small, weak swell and not a single standout session that gets the heart pumping. Most of the time, the wind is just on the wrong side of the compass, and the wave energy is gutless. But there’s a flicker of hope right at the end.
The first real chance to paddle out comes on Friday, July 30th. The morning is your best bet. We’ve got a clean, moderate offshore wind from the northwest, blowing at 15 mph, grooming the surface. The swell is tiny at 2 ft from the SSE with a period of 9 seconds, so it’s not going to be big, but the combined energy is a weak 95, so you’ll be scraping for little shoulders. The water temp is a normal 75°, so nothing unusual there. It’s surfable, but it’s honest work. The afternoon picks up a bit more energy – 141 – but the wind veers, and the quality drops off.
Then we hit a dead zone. From Saturday, August 1st, right through to Thursday, August 7th, it’s a flat, choppy mess. The wind is relentless from the south, blowing cross-onshore, and the swell is tiny. It’s a six-day gap where the only thing breaking is the mood. The combined energy rarely climbs above 100, and even when it does, the conditions are lumpy. Honestly, this stretch looks more interesting for a kite surfer than a paddle surfer – the wind is strong and consistent, but the waves are just poor.
The one true standout in this entire forecast is the morning of Friday, August 7th. This is the one to circle. The combined energy of all swells directed here hits 225 (moderate energy), with a 5 ft swell from the south. The period is a short 6 seconds, so it’s a windswell, but the wind is a light, cross-offshore breeze from the southwest at 9 mph, keeping the surface clean. It’s the only session in the whole run that’s scored as “good surf conditions.” This is a proper morning for Diamond Beach. The swell is just over 5 ft, so it’s a bit meaty for the groms, but intermediate to advanced surfers will find some punchy, little lefts if they’re positioned right. Don’t expect a perfect point break wave – it’s an exposed beach, so it’ll be a bit walled-up, but with those clean conditions, it’s the best on offer by a long shot. The afternoon of that same day falls apart again, so get it while it’s good.
That’s the story. A whole lot of waiting for one Friday morning.
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.
