Alright, Rusty here, let's look at what's on offer for Diamond Beach.
Well, mate, I won't beat around the bush – this stretch is looking pretty flat for a good, long while. The forecast shows we’re in for a real quiet spell, with a gap of about a week and a half where you’d be better off doing just about anything else. The first time we see any real energy is on Saturday the 18th of July, and even then it’s nothing to write home about.
Let’s start with a bit of context. The water's sitting at a very warm 76°, which is a solid 5° warmer than normal for this time of year, so you'll be in boardshorts or a light spring suit if you're brave.
For the morning of Saturday the 18th, we finally get a pulse of swell from the SSE. It's pushing 3ft, which is small but not completely flat, with a period of 8 seconds. The combined energy is just cracking into the moderate range at 148, so it’s got a tiny bit of push. The key here is the wind – we’ve got a light breeze from the west, keeping things clean. It’s surfable, but it’s very ordinary. If you’re desperate, it’s the only game in town.
Sunday the 19th morning is a similar story. The swell drops a touch to 3ft from the SSE, but the wind swings around to a moderate WNW offshore. That’s a major positive for clean faces. The energy is still moderate at 116, but again, don’t expect any power. This is a beginner-friendly wave size, so it's manageable, but the lack of oomph is the real let-down.
Diamond Beach is an exposed beach break, so it needs a bit of consistency to hold shape, and this short-period, weak energy swell just isn't delivering that. The best of a mediocre bunch is Saturday morning and Sunday morning – they’re clean because of the offshore winds, but the waves are weak and gutless.
Honestly, for most of the next two weeks, the setup looks more interesting for a kite session than a paddle surf. The wind and small, choppy conditions are far better suited to that.
Keep an eye on the charts, but for now, we’re waiting.
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.
