Alright folks, Rusty here. Let’s have a look at what’s on the cards for Diamond Beach over the next couple of weeks.

Honestly, I’ve gotta be straight with you – it’s a grim stretch ahead. The forecast is showing a long, quiet run with barely a wave worth paddling for. We’re looking at a solid week and a half of nothing really happening. The first real hint of anything surfable doesn’t show up until Saturday the 18th of July, and even then, it’s nothing to write home about.

For the first week, from Friday the 10th right through to Friday the 17th, it’s a total write-off. The swell is tiny, mostly around 1ft to 2ft, coming in from the east and southeast with short, weak periods of 4 to 9 seconds. The combined energy is very weak, between 11 and 73. Winds are all over the shop, mostly cross or cross-onshore, keeping things choppy and messy. There’s just no push, no power.

The first day that even gets a nod is Saturday the 18th. The morning has a little 3ft swell from the SSW, period 6 seconds, with a light WNW cross-offshore breeze making it clean. The energy is still weak at 65. It’s surfable, but only just – a tiny, weak wave for the beginner crew. The afternoon sees a bit more size, 4ft from the south, but the wind swings cross-shore and chops it up.

Then Sunday the 19th of July morning is worth a mention. We’ve got 2ft from the SSE, period 8 seconds, with the wind going totally glassy – calm, no wind. That’s a rare treat. The wave energy is moderate at 71. It’s small, but for a beginner or someone on a log, those clean, glassy conditions could be a nice little session. Afternoon gets a bit of a cross-off breeze, keeping it clean, but the swell stays small.

After that, from Monday the 20th through to the end of the forecast on the 25th, it’s back to poor conditions. The swell tries to pick up a bit, with 4ft to 5ft from the south and SSE, and the energy climbs into the moderate range (106 to 279), but the wind is almost always cross-onshore from the east or southeast, making it choppy and bumpy. It’s a messy, blown-out vibe.

So, to be clear, there’s no standout swell here. The best on offer is the glassy Sunday morning the 19th – it’s clean, but tiny. And the Saturday the 18th morning has a clean window on a very small wave. If you’re desperate for a paddle, those are your windows. Otherwise, you’re better off waiting for the next system to roll in. The water temp is about average for this time of year, so no surprises there.

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.
