Table - best surf conditions forecast for Diamond Beach over the next 16 days.
Alright, let me tell you what I'm seeing for Diamond Beach over the next few weeks. Honestly, for most of this run, it’s going to be a tough watch.
We start off with absolutely no swell to speak of for the first week. From Wednesday the 8th right through to late Monday the 13th, it’s a whole lot of nothing. The energy is weak, the wind is mostly onshore or cross-shore, and every single report just says "poor surf conditions." You’d be wasting your time paddling out on those tiny, choppy 1.0 ft to 3 ft waves. It’s flat, folks.
The water temperature is 76°, which is much warmer than normal for this time of year – a real anomaly of 4°, so jump in without the thick rubber if you can handle the lack of waves.
Then, finally, there’s a glimmer. On the morning of Tuesday, July 14, we get a pulse of energy. The combined swell energy jumps to 503 (moderate wave energy), with a 6 ft swell coming from the ESE. The wind goes glassy – dead calm from the west at 3 mph. This is the real standout of the entire 16-day forecast. The conditions will be excellent for a wave that size, which is getting into the territory of being a bit much for beginners. The period is 8 seconds, so it’s a bit of local wind swell, not a long-period groundswell, but with those clean, glassy conditions, it should offer some fun, punchy waves. Of course, crowds are sometimes an issue at Diamond Beach, so get out there early.
After that Tuesday morning sweet spot, it dries up again. The rest of the week and into the weekend sees the swell drop right back down below 3 ft, and the wind shifts back into the cross/onshore range, making for choppy or weak conditions again. There’s a brief moment on the afternoon of July 21 where the wind goes glassy again, but the swell is tiny – only 4 ft from the south with very weak energy (94), so it's barely surfable.
All in all, if you’re itching for a paddle, the only session worth chasing is that Tuesday the 14th morning. The rest is a waiting game for the next proper swell.

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.
