The Lowdown
Alright, surfers, Rusty here. Let’s look at what’s on the cards for Diamond Beach. Right off the bat, I gotta be straight with you – this is a grim stretch. The next week and a half is mostly a write-off, with a whole lot of flat, choppy, or just plain messy conditions. Don’t even bother looking at the shore until the calendar flips to August.
We’re staring down a long dry spell. From now through the end of July, it’s practically all poor surf with zilch for recommendations. The waves are tiny, under 3ft, the wind is mostly cross or onshore, and the energy is weak. The best you’ll see is a fleeting moment on Wednesday morning the 29th with a clean 3ft SSE swell under moderate offshore winds, but the score is still a 1 – surfable, but very ordinary. That’s not a session to get excited about.
Then we hit the real blank. The first few days of August are more of the same junk. You’ll be waiting until Monday the 3rd of August for the first and only real glimmer of hope. Finally, the swell picks up. Monday morning the 3rd sees a clean 4ft SSE swell with a 9-second period and light offshore winds from the NW. The combined swell energy jumps to 226 (moderate) – a real sign of life. This is the standout, the only window worth planning for. It’s not huge, but it’s the best we’ve got. The wind will be light and offshore, so expect clean lines. Just keep in mind, Diamond Beach is exposed to the SE, and the swell is coming from the SSE, so it’s a good match. For a beginner, 4ft is manageable, but if it gets a bit punchy, it might be a tad much.
After that, the energy fades back to weak and the recommendations drop off again. The rest of the second week looks like more of the same nothing. So, draw a circle around Monday the 3rd of August and hope the forecasts hold. It’s been a long time coming.
Stay salty,
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.
