The Lowdown

Alright, this is Rusty, and I’m taking a look at what’s coming up for Diamond Beach. Gotta be straight with you – the next 16 days are looking pretty grim. There’s a long stretch of nothing happening here, and I mean a solid run of flat-to-weak, messy conditions. Let’s get into it.

We start off with a bit of a tease on Monday the 27th of July, but it’s a total write-off. A risk of thunderstorms, a cross-on shore breeze, and only a tiny 1ft swell from the southeast with a period of just 8 seconds. The combined energy is weak (25), and the water's sitting at 74°, which is about average for this time of year. The surf is poor, and it’s not worth paddling out.

Tuesday the 28th is even worse. The wind ramps up to 22 mph from the SSW, creating a lumpy, cross-onshore mess. The swell bumps up to 5ft, but it’s a choppy, short-period windswell from the south with a shocking 4-second period. The combined energy climbs to a moderate 115, but it’s just a messy, blown-out wall. Not for paddle surfing – this setup looks more interesting for kite surfing.

Wednesday the 29th morning offers a glimmer of hope. The wind swings to the WNW at 6 mph, giving us a clean, cross-offshore breeze. The swell drops to 2ft from the southeast at 7 seconds. The combined energy is weak (87). The report says “surfable waves but very ordinary conditions,” so it’s rideable but tiny and weak. Not a standout.

From Wednesday afternoon right through to the end of the forecast period on August 11th, it’s a long, flat spell. The swell stays below 2ft, mostly between 0.3ft and 2ft, with periods all over the place but mostly short. The wind is often onshore or cross-shore, keeping things choppy or messy. There are a few moments of clean, offshore wind (like Thursday the 30th afternoon and Friday the 31st morning), but the swell is just too small – 1ft to 2ft – to push any real waves. The combined energy is weak, often in the single digits or low double digits.

The most notable thing is the lack of any real swell. Even when the wind is good, there’s no wave energy to work with. For a beginner, there’s nothing here that’s safe or fun. For anyone else, it’s a flat spell. The only real highlight, if you can call it that, is the Wednesday the 29th morning session, where you might get a few clean, knee-high rollers. But it’s not a standout.

So, honestly, the best advice is to leave the board at home. There’s no good surf on offer in this 16-day window. The area is going through a quiet, consistent run of poor conditions, which is more normal for this spot when the swell hasn’t shown up. Forecasts can change, but for now, it’s a bust.

Stay patient, and keep an eye on the horizon.

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.
