Table - best surf conditions forecast for Diamond Beach over the next 16 days.
Alright folks, Rusty here. Let’s be straight with you about Diamond Beach. Looking at the full 16-day window, the honest truth is there’s barely a whisper of surf worth paddling for. The whole first week, from Friday the 10th right through to the end of Sunday the 20th, is a dead zone. You’re looking at nothing but tiny, weak waves – mostly 1ft to 2.3ft – with junk winds and a combined energy that barely reaches double digits (mostly 24 or less). It’s a total write-off for a surf. Don’t bother.
The only flicker of life comes right at the tail end of the forecast. On Tuesday the 21st, we finally see something that’s not a total washout. The swell bumps up to a clean 3.3ft from the East, with a period of 7 seconds. The wind turns offshore from the Northwest, which is a major positive, giving us clean conditions. The combined energy gets into triple digits (102-119), which is at least moderate. It’s still not a classic, but it’s surfable. The rest of that week stays marginal, with the wind swinging around and the energy dropping back off. So, if you’re desperate, the 21st is your only real look.
Diamond Beach is an exposed beginner spot, and it’s inconsistent. With the water temp sitting at 74.8°, that’s a touch warmer than normal for the time of year, which is a nice little bonus if you do get in. But honestly, this is a long blank run. For an area like this, a stretch of quiet weather is pretty normal. Don’t hold your breath; check back in a few days.

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.
