The Lowdown

Alright, let's get into it. Rusty here, looking over the next couple of weeks for Diamond Beach.

Unfortunately, this stretch looks flat as a pancake for a good long while. It's a tough run for any of you looking to paddle out at Diamond Beach. The first recommendation doesn't even pop up until Thursday the 27th of August, and even then, it's not exactly something to write home about. You're facing about a week and a half of tiny, weak surf. The wave energy is barely registering. We're talking combined energies in the teens and low twenties (14 to 49), which is basically nothing. Just a whole lot of waiting.

For the first few days, from Thursday the 27th through the end of August, you've got tiny 1 ft to 3 ft waves mostly from the ESE and ENE. Short period, too, mostly around 4 to 8 seconds – that's pure wind chop, not any real swell. The wind is all over the place, mostly cross or cross-onshore, so it's gonna be choppy. The morning of Sunday the 30th does have a window of absolute glass, with the sea like a mirror, but with only 1 ft of swell, it's barely a ripple.

Then we slide into a whole week of September, from the 1st to the 7th, and it's more of the same. Tiny surf, rarely cracking 1 ft for most of it, and the energy is still pathetic. The morning of Tuesday the 1st and the morning of Wednesday the 2nd have some clean windows with light offshore or glassy conditions. Wednesday the 2nd even sees a jump in period to 11 seconds, a bit more of a groundswell signal, but the height is still only 1 ft. It’s just not enough to get excited about. The water temp is about 76°, which is a touch warmer than normal for this time of year.

Now, we finally get a little bump on Sunday the 6th of September. The swell height picks up to 4 ft from the ENE, and the combined energy jumps to a moderate 124. But the wind is a fresh cross-onshore at 19 mph, making it lumpy and ugly. For a beach break setup like Diamond Beach, with onshore winds, it's going to be a mess. This kind of energy and bump is really more interesting for the kiteboarders than for anyone with a paddle.

The following week does offer some cleaner conditions. Monday the 7th and Friday the 11th of September both have clean, offshore or cross-offshore wind windows with gentle breezes. Friday morning the 11th looks prime with a gentle offshore from the NW. But again, the swell is tiny, at 1.0 ft. It’s clean enough for a longboard if you really want to get wet, but don't expect to catch much more than a ripple.

Overall, this is a rough 16-day outlook for Diamond Beach. It’s a classic case of a spot that goes completely quiet for long stretches. Don't hold your breath. Sometimes the ocean just takes a nap. Keep your eyes on the forecast, though – it can turn around.

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.
