The Lowdown
G'day, I'm Rusty, and I've got the local gen on Diamond Beach. Let's be straight, it's been a tough run for surf here. Looking at the next 16 days, starting from the beginning of September, the truth is there’s barely a wave worth paddling for during the first couple of weeks. The swell just isn’t showing up. You'd be waiting for days—over a week, in fact—with nothing but tiny, weak, and messy conditions.
From the 3rd through to the 15th of September, it's a flat spell. The swell heights are mostly under 3 feet, with a combined swell energy that's barely registering—stuck in the weak range at best, and often just teeny values. The period is short and choppy, and even when the wind is offshore or glassy, the swell is too small and weak to do anything with. It’s the kind of stretch where you’re better off finding another hobby.
Things finally tease a chance on Wednesday the 16th of September. The morning session is the only real window in the whole outlook. You’ve got a clean 2 feet swell from the East with a 10-second period, giving it a bit more shape, and a light offshore breeze from the NNW. The combined energy stays weak though. It's described as "ordinary", so don't get your hopes up. Any ride will be a battle.
It’s worth noting that Diamond Beach here is an exposed, inconsistent beach break for beginners. The wind looks better than the swell. If the swell was significant, the cross-shore/onshore wind and beach setup might make this more interesting for the kite crew than for us, but with the swell so flat, even that’s not a thing.
No standout sessions here, folks. The best on offer is that Wednesday the 16th morning, but it’s weak. A long-range look towards the end of the period on the 18th shows a longer-period swell (13 seconds) but with rain and onshore wind, so it’s a write-off. Keep an eye on the charts, because it tends not to stay this quiet forever.

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.
