Alright, Rusty here. Let’s give it to you straight for Diamond Beach.
Truth is, the next couple of weeks are looking pretty bleak. There’s barely a whisper of surf for the first week, and what little shows up is plagued by poor conditions. We’ve got a long stretch of small, weak swell and tricky winds. The only real glimmer of hope doesn’t arrive until Saturday, July 11th, but it’s not much to write home about.
Let’s start with the first proper day where the wave energy gets to a moderate level. On the morning of Saturday, July 11th, we see the combined swell energy hit 127 (moderate) with a clean, cross-offshore wind from the WNW at 16 mph. The swell is a measly 3 ft from the SSE, with a period of 8 seconds. It’s clean, but the size is tiny. That afternoon, the wind turns offshore from the NW at 16 mph, making for clean conditions, but the energy drops right back down to 66 (weak). The waves are surfable but very ordinary.
Honestly, nothing in this entire window jumps out as a standout. The swell never gets over 5 ft, so it’s never a worry for beginners, but it’s also never really got any punch. For a spot that's exposed to swell, it’s a frustrating run. The consistent lack of any real groundswell and the constant cross-shore or onshore winds just kill the vibe. Don’t hold your breath. Forecasts can change, but right now, it’s a tough period for Diamond Beach.
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.
