The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Diamond Beach. We're running a 16-day window, and to be honest, it's a pretty quiet stretch. There's no real swell to speak of, and the conditions are mostly ordinary, so we're in for a bit of a wait.
The first surfable moment pops up on Thursday, the 23rd of July. The morning session is your best bet, with a small 2ft SSE swell pushing in at a short period of 8 seconds. The combined energy is weak (77), so we're talking knee-high stuff at best. The wind is a gentle cross-offshore, which will keep things tidy. It's a clean little wave, but beginners will be fine in this size. After that, it's a rough run of days. From Thursday afternoon all the way through to the 28th, it's a write-off. The wind is onshore, chopping up the surface, and the swell is tiny, so there's nothing worth paddling out for.
We get another brief window on Wednesday, the 29th of July. Early morning, we've got a similar 2ft swell from the SSE, with a light cross-off breeze keeping it clean. The energy is still very low (67), so don't expect much push. Thursday morning, the 30th, is also a consideration, with a 2ft SSE swell, light cross-off wind, and a bit more period at 9 seconds. It's surfable, but again, nothing to get amped about.
Honestly, after that, it's a long, dry spell. There are no standout days in the second week at all. We see a few more clean mornings with light winds, like the 1st and 2nd of August, but the swell is non-existent at 1ft to 2ft. The energy numbers are well below 100, meaning it's flat. The whole period is a struggle for decent surf. The water temp is about average for this time of year, so no surprises there.
If you're desperate for a paddle, the Thursday morning (30th July) is the pick of a very average bunch. The 2ft SSE swell and light cross-off wind will give you the cleanest conditions, but it's purely a longboard or foamie session. For the rest of the time, you're better off checking the forecast again in a few days. This is one of those quiet periods that happens.
Keep your chin up, the swell will swing back around eventually.
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.
