The Lowdown
Alright, Rusty here, and let's be straight with you.
We are looking at a flat spell for Diamond Beach. This spot is beginner-friendly and likes swell from the SE, but we just aren't getting it over these 16 days. The whole run is a write-off. Nothing is even worth a paddle. The scores are rock bottom from the first day to the last. It's a long dry stretch.
Kicking off on Tuesday the 8th, you've got a tiny 0.7ft swell from the east with a 9-second period. The energy is weak. The water is notably warm at 77°, which is much warmer than normal. The wind is light in the morning but gets worse. Wednesday the 9th has a slightly bigger wave but drops into a short, choppy 4-second period from the SSW, making for lumpy, poor conditions all day.
Thursday the 10th has a 4ft swell in the morning with cross-off wind, and the best looking window is actually the afternoon when the wind turns offshore from the NW, even though the swell drops to 2ft. That's small and clean, but still not enough to get excited about. The rest of the days through the end of the second week offer nothing but poor surf conditions.
In the second week, we see a couple of days with offshore winds, like Monday the 14th when it goes glassy and Monday the 16th with clean offshore wind, but the swell is still tiny at around 1ft to 2ft. By the 23rd of September, the last day, the swell reaches 2ft from the SE with moderate energy, but the wind is a messy cross-onshore, making it choppy. For a surf, there's nothing.
Sometimes in this area, you just get a blank run. It happens. It's not the end of the world. Forecasts change, so check back in. But for now? Grab a kite if you've got one, because the bigger breezes will be more fun than a surfboard.
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.
