Table - best surf conditions forecast for Diamond Beach over the next 16 days.


Alright, Rusty here. Let's take a look at what's cookin' over the next couple of weeks.

To be straight with you, it's gonna be a long, quiet stretch. We're looking at a massive gap with no real surf on offer until Wednesday, July 15th. From now until then, it's mostly flat, choppy, or just plain poor. Don't bother paddling out.

Finally, on the morning of Wednesday, July 15th, we get a little pulse of life at Diamond Beach. Swell will be a tiny 2ft out of the SE with an 8-second period, and the combined swell energy is weak (100). The real story here is the wind: it's forecast to be glassy (SSE at 5 km/h). That's a major positive and the reason this is the only session worth mentioning. The water temp is about average for this time of year. The break is exposed to the SE, which lines up okay. Keep in mind, Diamond Beach is an inconsistent spot and can be a bit of a lottery, but with the glassy conditions, a log might just be the call for a few fun little runners. Crowds are sometimes a factor here. This is your only real shot in the whole 16 days.

Beyond that, the rest of the forecast falls away again. There's a couple of mornings with clean, offshore winds around the 21st, like Tuesday morning, July 21st, when a light WNW breeze (9 mph) creates clean conditions, but the swell is tiny (2ft out of the S, 25 combined energy). You'd be scratching for anything.

It's a flat run. Don't get your hopes up too early.

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.
