The Lowdown
G'day, Rusty here. Look, I've scanned the charts for the next couple of weeks, and I gotta be straight with you – it's a flat spell. There's absolutely nothing on the cards worth paddling out for. The entire 16-day window is a write-off, with no surfable options at all. It's one of those blank runs that can happen here, so don't throw your boards in the shed just yet; it tends not to stay this quiet for long.
The only spot in the frame is Diamond Beach. It's a beginner-friendly, exposed beach break that needs a solid SE swell to work, and we just aren't getting it. The water temperature is about average for this time of year, so no surprises there.
Let's walk through the misery. Friday the 4th, we've got a tiny 1.0 ft to 1 ft SE swell with a short 8-second period, producing weak energy. The wind is offshore, but it's just too small to bother. Saturday and Sunday are even worse – barely a ripple. Monday the 7th sees a little bump from the east at 2 ft, with a 10-second period and moderate energy. The wind is clean, but the forecast says "surfable waves but very ordinary conditions," and a score of 1 out of 10 tells the real story. It's not worth the wet suit.
The following week doesn't get any better. A few days show a bit of a NE swell around 3 ft on the 13th, but the wind is onshore or cross, and it's just messy. Later in the week, the 19th of September has a 4 ft ESE swell with a fresh offshore breeze, but the period is a short 6 seconds, and the energy is still weak. It's a clean, choppy mess, not a wave.
Honestly, for the whole 16 days, every single forecast is a "poor surf conditions" or worse. The best you could hope for is a clean, flat ocean. The setup looks more interesting for kite surfing than paddle surfing if the wind picks up, but for us surfers, it's a total bust. Keep your stick on the rack, lads.

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.
