The Lowdown
Alright, let’s get real about this stretch. I’m looking at the 16-day window here, and honestly, it’s a tough one for Diamond Beach. The whole period is a dry spell for decent surf – no standouts, no real windows, just a whole lot of nothing to get excited about. The swell is tiny, the wind is messy, and the conditions are just plain poor. It’s one of those runs where you’re better off leaving the boards in the car and finding something else to do.
The first few days – from Sunday, August 2nd through to the end of the first week – are a write-off. Swell heights barely nudge past 3 ft to 4 ft, but the wind is mostly onshore or cross-onshore, coming from the SSE or S, with speeds around 15–16 mph. That’s kicking up chop and making a mess of things. The combined wave energy is weak, mostly in the 20s to 80s (energy values: 26, 40, 211, 206, 62, 55, etc.), so there’s just no power behind it. The swell period is short – 4 to 8 seconds – so it’s all windswell, no shape, no punch. Diamond Beach is inconsistent at the best of times, and this is about as flat and ugly as it gets.
Midweek, around August 7th and 8th, there’s a slight improvement with light cross-shore winds, but the swell is still tiny – 2 ft to 3 ft, period around 5–6 seconds, energy barely over 100 (110 on the 7th morning). It’s still not worth paddling out. The water temperature is sitting at 75°F, which is about average for this time of year, so no surprises there.
The second week doesn’t get any better. From August 10th through to the 17th, it’s more of the same: small swells, mostly below 3 ft, with the occasional puff of energy but never enough to break clean. The wind does go offshore or cross-offshore a few times – like on the 12th and 15th – but with swell heights of 1.0 ft to 2 ft and periods of 4–6 seconds, it’s barely a ripple. The combined energy drops even further, into the teens and 20s (14, 21, 23, 17, 29). By the 17th, you get a moderate offshore breeze from the NNW, but again, the swell is only 1 ft to 2 ft. It’s clean, but there’s nothing to ride.
So what’s the bottom line? There are no good surf options in this 16-day window. Zero. If you’re desperate, maybe the 17th morning offers a glassy clean look at something tiny, but it’s more of a paddle than a surf. Diamond Beach is a fairly inconsistent spot, and this kind of blank run is normal for the area when the swell direction and wind don’t line up. Forecasts can change, but right now, it’s a hard pass.
Stay tuned, keep your eyes on the charts, but for now, I’d say take a break.

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.
