The Lowdown
Alright, let me level with you. I'm looking at the whole 16-day window for Diamond Beach, and honestly, it's a bit of a tough stretch. The swell just isn't cooperating, and the wind is rarely on our side.
We're starting with a bit of a flat spell. There's nothing really worth paddling out for in the first few days. The surf is poor, and the wind is mostly cross-onshore or choppy. We get a small window of clean conditions on Saturday the 8th with a light offshore breeze, but the swell is tiny at 2ft from the South. It's a glorified lake paddle, not a surf session.
The pattern continues with small, weak swell and messy wind through the following week. The standout moment, if you can call it that, is actually in the second week. On Monday the 17th, the morning looks absolutely glassy, with the wind dropping to almost nothing. The swell is utterly tiny at just 0.6ft from the SSE, but the period is a surprisingly long 9 seconds. The combined energy is a measly 15 (weak). It's not going to break properly, but if you just want to sit on your board and watch the sun come up, it's the most peaceful the ocean will be all fortnight.
For a beginner, the swell never gets above 5ft, so the size isn't an issue, but the lack of any quality and the constant choppy conditions mean it's not a good time to learn. The water temp is about average for this time of year, so no shocks there.
Honestly, this is a blank run. The models are showing next to nothing. For Diamond Beach, an exposed beach break, this kind of flat, windy spell is pretty normal. It tends not to stay this poor for long, but for now, leave the board in the garage.

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.
