The Lowdown
Howdy, Rusty here. Let’s break down what’s coming over the next couple of weeks, surf-wise.
First off, the bad news: we’ve got a major dry spell. From July 25th all the way through the end of the month, there’s really nothing worth paddling out for. Days of weak, tiny swell and onshore junk. The combined swell energy barely cracks double digits at times, so you’re better off keeping the board in the car.
The first time we see a real bump in energy is on Sunday, August 3rd. The swell jumps to a moderate 157 (combined energy) with 3ft from the SSE and a period of 9 seconds. The wind will be a gentle cross-shore from the NE, so it won’t be a total mess, but the data still calls it poor. It’ll be surfable but very average. Not worth getting up early for.
Friday morning, July 31st, offers our only clean window early on. Offshore wind from the WNW at 6 mph, glassy conditions, but swell is a pathetic 2ft. You’d be on a longboard hoping for a micro-ripple.
Into the second week, the cleanest mornings are on Wednesday, August 5th, and Friday, August 7th. On the 5th, we get offshore wind from the WNW at 3 mph and clean conditions with 2ft of SSE swell. On the 7th, a cross-offshore breeze from the NNE at 9 mph with 2ft of swell. Both are tiny, weak, and the energy readings are low (39 and 38 respectively). Not going to win any awards.
Diamond Beach is a beach break that’s inconsistent and hardly ever pumps. The water temperature is about 75°, pretty standard for this time of year.
The bottom line is, there’s no real standout in this whole 16-day window. The best you could hope for is a few tiny, clean waves on one of those offshore mornings, but don’t expect any power or push. For a beginner, none of this gets too big, so it’s safe, but the quality is just not there.
Keep your eyes on the forecast – things can always change.
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.
