The Lowdown
Alright folks, Rusty here. Let’s get real about what’s on the table for the next couple of weeks.
Honestly, this is a tough one. The forecast is looking pretty bleak for a solid stretch. I’m looking at Diamond Beach (Beginner) and I gotta say, for the next ten days or so, it’s pretty much a write-off. That’s a long gap with nothing worth paddling out for. The swell is tiny, the period is short, and the energy is weak. You’ll see combined energy values hanging around 18 to 130, which is in the weak to low-moderate range, but it’s mostly messy and poorly directed.
The water temp is sitting at 74°F with a tiny anomaly of 1°F, so it’s pretty much average for this time of year. Nothing exciting there.
The first real glimmer of hope doesn’t show up until Sunday, the 26th of July. That morning, we’ve got a clean 3ft swell from the S with a 7-second period, combined energy of 62, and gentle offshore winds from the NW. It’s not big, not powerful, but it’s surfable without being a total battle. The afternoon holds similar with a 3ft SSE swell, 8-second period, 78 energy, and still clean offshore breeze from the WNW. This is the best on offer, but it’s more of a longboard cruise or a learner session than a standout. The break is inconsistent, so you’ll be waiting for sets, and crowds are possible, so don’t expect it to be empty.
There’s nothing else to recommend after that Monday morning. The pattern just fades back into tiny, onshore junk. A real bummer of a run.
Stay patient, fellas. The ocean will sort itself out.

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.
