The Lowdown
Alright, mate, Rusty here with the Imperial version. Let's look at Diamond Beach. The 16-day outlook is pretty bleak. We've got a lot of small, messy surf with onshore wind, and there's a long stretch of flatness in the second week.
The one and only window worth paddling for is Monday morning, August 3rd. The wind is light and cross-offshore from the WNW, cleaning up the surface nicely. We'll see chest-high swell at about 6 ft from the SSE, with moderate wave energy (624). The period is around 8 seconds, so the waves will have some push. The water temp is about average for the season. It's an exposed SE beach, and it can get a bit of a crowd, so be ready for that.
Outside of that Monday morning, it's a tough outlook. You get a few clean mornings on the 10th and 11th, but the swell is tiny, barely 2 to 3 ft. It's longboard territory if you're desperate, but nothing to write home about.
From the 12th of August onward, it's flat. Swell heights drop below 2 ft with almost no energy. You're looking at a solid week of nothing rideable. This is a normal pattern for the area when the surf goes silent.
Keep the board waxed, but don't rush down.

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.
