Alright, this is Rusty. I’ll level with you, it’s been a real dry spell. The first decent chance to get wet isn’t until Saturday, July 12th. That’s a big gap of over a week with nothing good.
For a break that’s inconsistent and built for beginners, this kind of quiet period is pretty typical.
The best we get is on Sunday, July 13th. There’s a 2ft east swell with a fresh offshore wind. Water temp is normal for the season. The offshore breeze will keep things clean. It’s tiny, but it’s the cleanest wave of the whole outlook. The combined energy is weak, reading 35.
Tuesday morning, July 15th, sees a little 1ft SE swell with glassy conditions. Again, super small but perfectly clean.
Don’t expect any real size; nothing tops 5ft, and the swell period is short most of the time, so the waves will be weak. It’s a beach break, so the setup isn’t helping either.
For paddle surfing, it’s a tough call. If the wind picks up, it might be more interesting for the kite surfers. That’s the hard truth from me.

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.
