The Lowdown
Alright, Rusty here. Let’s be straight with you – this is a tough outlook for Diamond Beach. We’ve got a solid 16-day window, but the ocean just isn’t cooperating. There’s a real gap here with no good surf to speak of for the first ten days, from Saturday the 25th of July right through to the end of the month. The swell is tiny, mostly around 1ft to 2ft, and the wind is nearly always cross or cross-on, keeping things messy and choppy. The water temp is sitting at 75°, which is pretty normal for this time of year, nothing to write home about. The combined wave energy is weak, barely cracking 100 (61 to 101 range), so there’s just no punch in the water.
The only real glimmer in this whole outlook comes on Tuesday the 4th of August. That afternoon the wind swings around to a light cross-off from the NNE, and the reports say the surf is clean. The swell is still small, only 2ft from the SSE, but that’s the best we’ve got. It’s a beginner-friendly wave, but don’t expect anything firing. The combined energy is only 63, so it’s still weak. If you’re desperate for a paddle, that’s your window. The break is exposed to the SE, and the swell is coming from the SSE, which isn’t its ideal direction, but it’s the best of a bad bunch.
After that, the rest of the week into August 9th is more of the same: tiny swell, onshore or cross-shore winds, and poor surf conditions. Even the couple of mornings with offshore or glassy wind (like the 6th and 7th of August) only have 1ft to 2ft of swell, so it’s flat and clean, not surfable. Don’t get your hopes up.
This is one of those stretches where the ocean just says no. Keep an eye on the forecasts, it can’t stay this flat forever.
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.
