Alright, Rusty here. Let’s have a proper look at what Diamond Beach has cookin’ for us over the next couple of weeks. I’ll be straight with ya – it’s a long, flat spell for the most part, but there’s a little blip of hope if you’ve got patience and a board for bigger, cleaner stuff.
Right now and for the next week or more, Diamond Beach is pretty much a write-off for a decent paddle. We’re talkin’ days of tiny, weak, and messy surf – starting Monday the 6th through to Sunday the 12th, you’ll be lookin’ at waves mostly under 3 ft, with short, weak periods and mostly cross-onshore or choppy wind. The combined energy barely climbs past 70 (weak), so it’s barely got any push. Not worth wetting the suit for. There’s a brief moment Saturday morning the 11th with glassy conditions and a tiny 1.0 ft swell, but the period’s a low 5 seconds – just not enough to ride.
The standout window finally appears on Monday morning, 13th July. The swell jumps to 6 ft from the east with a period of 7 seconds, and the combined energy hits 295 (moderate). The wind’s a light north cross-off, so it should be clean. That wave comment says “expect good surf conditions,” so my gut says get out there early. The water’s sitting at a very warm 76°F, which is a massive 5°F warmer than usual for this time of year – you’ll be sweating in your wettie. The break is exposed to southeast swell, and we’ve got east swell hitting it, which is off the optimum direction but the size and clean conditions make it the pick of the entire period. Keep in mind Diamond Beach can be inconsistent, and it’s a beginner-friendly spot – this 6 ft might be a little big for total beginners, but for most of ya, it’s fine.
Tuesday morning the 14th is the real heavy hitter for experienced surfers only. The swell jumps to 7 ft from the east, period 9 seconds, and the combined energy absolutely hammers in at 1029 (strong to very strong). Wind is west-southwest cross-off, so glassy clean conditions. This is solid, powerful groundswell – but at over 8 ft, it’s expert territory. The wave comment says “excellent surf conditions for experienced surfers”, so if you’ve got the skills, this is your session. Just be aware that with this much east swell on an exposed beach, it’ll be a ripping paddle and you’ll want to pick your peak carefully. Crowds are possible here sometimes, so expect company if it’s firing.
After that Tuesday morning pulse, it fades fast – Tuesday afternoon drops to 4 ft with cross-on wind and shoddy quality. From Wednesday the 15th onward, we’re back to tiny, weak dribble for the rest of the 16 days – mostly under 2 ft, with combined energy dropping below 100, and wind often clean but just no size to work with. There’s a brief moment on Sunday the 19th morning with 2 ft and clean offshore breeze, but it’s still too small to get excited about.
So here’s the deal: the best on offer is Monday morning the 13th for a fun, clean session on a decent 6 ft east swell, and Tuesday morning the 14th for the big dogs who want a powerful 7 ft east swell with glassy conditions. Everything else is flat and quiet. Don’t hold your breath for the second week – it’s a long run of small stuff.
Stay stoked, check the tides, and don’t paddle out alone on that Tuesday morning if you’re not ready for it.
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.
