Alright, let me take a look at what we’ve got for Diamond Beach. Straight up, this is a tough run. I’m looking at the whole 16-day window, and honestly, there’s nothing I’d call a good surf option here. The swell is tiny, and the energy is weak the whole way through – we're talking combined energy mostly under 30 (17, 29, 14), barely enough to push a foamie around. The water temp is about average for this time of year, nothing weird there.
Kicking off Friday July 3rd, you’ve got a 0.7ft ESE swell with a 9 second period. Wind is light and cross-offshore first thing, so it’s clean, but there’s just no power. That sets the tone for the next few days. Saturday the 4th and Sunday the 5th are much the same – tiny waves, poor conditions, and Sunday brings rain and onshore wind, so don’t bother.
Monday the 6th sees a tiny spike to 2ft but the period crashes to 3 seconds – that’s just wind chop, not surf. Tuesday the 7th is clean with light cross-offshore winds and a 2-2ft SSE swell, period around 6 seconds, energy at 30 to 49. It’s clean, but it’s weak and gutless. Not worth getting wet for anything more than a splash.
Wednesday the 8th is the biggest we see, with the swell touching 2ft and energy hitting 108 – that’s moderate energy for the first time – but the wind is cross-shore and choppy, and the direction is E, not really lining up with the SE optimum. Still marginal. Thursday the 9th goes back to small and onshore.
Through the second week, it’s more of the same. Best looks are Saturday the 12th and Sunday the 13th, where you get clean mornings with light offshore or cross-offshore wind, but wave heights stay below 2ft and periods are short, 5 to 8 seconds. Energy never gets above 57. The 14th and 15th have clean mornings with offshore breezes, but again, it’s knee-high dribble.
From the 16th onward, the wind gets worse – fresh onshore breezes, choppy, messy. Nothing to recommend.
Look, this is a spot that’s exposed to the SE, and the swell just never shows up in any meaningful way. The crowd is listed as “sometimes,” but with surf this poor, you probably won’t see anyone. There’s no standout, no session worth circling on the calendar. If you’re desperate for a paddle, the cleanest windows are the mornings of the 7th, 12th, 13th, and 15th, but keep your expectations real low.
Honestly, for this stretch, a kite might have more fun than a surfboard.

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.
