The Lowdown

Alright, grab your board. Rusty here, and I've got the lowdown on the next couple of weeks at Diamond Beach. Let's be straight with you – it's looking like a tough stretch. We're in for a long dry spell.

The whole 16-day window is a bit of a bummer, to be honest. The swell is tiny and the energy is just not there. The combined swell energy barely cracks 100 (103) on one afternoon, and that's about as exciting as it gets. Most of the time, we're looking at weak energy in the 20s to 80s range. For a surfer wanting a proper wave, this is a lean period.

Right now, it's Wednesday morning, the 29th of July, and we've got a tiny 2ft swell from the SSE with a period of just 6 seconds – that's short-period wind chop, not groundswell. The wind is a fresh offshore from the WNW at 19 mph, which keeps the surface clean, but there's just no push to the waves. The water temp is a tame 75°, which is bang on average for this time of year, so no wetsuit drama there.

We will have a few days of this. There's a glimmer of hope on Friday morning, the 31st, when the wind goes glassy. The swell is only 1ft from the SE with a period of 8 seconds, so it's tiny, but those glassy conditions will make it look pretty. If you're desperate for a paddle, that's your best bet for a clean, tiny wave, but don't expect to get your hair wet.

Then we get into a period of onshore and cross-onshore winds that will chop up whatever weak swell is there. It's pretty ordinary. The best chance we see for anything remotely surfable is on Monday, August 3rd, in the afternoon. We'll have a 3ft SSE swell, but the wind goes light cross-offshore from the WSW at 9 mph, cleaning things up. The combined energy is a weak 70. It's surfable, but it's very ordinary.

The pattern continues with small, weak swells. The only other time we see a spike in energy is on Saturday, August 8th, the afternoon, when a 3ft S swell with an 8-second period pushes the combined energy to 121 (moderate). But the wind is a moderate cross-onshore from the south at 12 mph, making it choppy and messy. Not worth the drive.

The very end of the window, on Thursday, August 13th, in the afternoon, shows a 5ft S swell with a period of 7 seconds and a combined energy of 280 (moderate). But the wind is a light cross-onshore, and the surf is described as marginal. It's a bit bigger, but it's not clean.

Honestly, there's no standout session here. The swell is too small and weak for the break to work properly. It's an exposed beach break, so it needs a bit more push. With the wind staying clean and the swell so small, this setup actually looks more interesting for a kite surfer than a paddle surfer. I'd hang the board up for a bit and wait for the next system to roll through.

Rusty, signing off.

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.
