G’day, Rusty here, and I’ve got the forecast for Diamond Beach. Honestly, it’s a grim stretch ahead for the next sixteen days out of the gate. This spot is a beginner-friendly, exposed beach break that rarely gets a decent pulse, and the next week and a half is mostly a write-off. We’ve got a long dry spell from now through to about the 23rd of July where there’s nothing worth paddling out for – the swell barely kicks above 0.7 ft, and when it does, the wind is all wrong, cross-onshore and choppy. The combined wave energy sits below 100 for most of that time, just weak and messy.

There’s a shift on Thursday the 24th of July. The morning is still ordinary – 4 ft of S swell with a period of 8 seconds, clean enough with a slight breeze cross-off from the north, but the energy is moderate at 188. It’s surfable but nothing to write home about. Then Thursday afternoon is the first real standout. We get 4 ft of S swell, period still 8 seconds, and the wind goes glassy from the south. That’s clean, lined-up waves, and the combined energy jumps to 202 – solid moderate. For a break that’s inconsistent and rarely breaks, this is the moment to be in the water. Expect crowds to be possible given the exposure, but with the setup being a beach break, that long-period groundswell (8 seconds isn’t long, but it’s steady) should offer some shape.

Friday the 25th of July morning holds a bit of that pulse – 4 ft S swell, period still 8 seconds, energy at 208 – but the wind swings cross from the NE, putting a slight chop on it. It’s marginal, and crowds are still likely. By the afternoon, it gets messy again with 5 ft S swell and cross-winds. After that, we drop back into nothingness for the 26th. The water temperature is about average for this time of year, no major anomaly to report. It’s a long wait, but that Thursday glassy session is the one to aim for – just don’t hold your breath for consistency. Keep an eye on the forecasts, because it tends not to stay poor forever.

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.
