The Lowdown
Alright, Rusty here, lookin’ at the waves.
Right off the bat, we’ve got some swell on the way, but it’s gonna be a dodgy week for clean conditions at Turtles. This is an advanced reef break, exposed to the swell, and from the get-go on Tuesday morning, August 25th, there’s a glimmer of hope. We’re looking at a solid 5ft SW groundswell (766 combined energy – moderate) with a long 13-second period, and the wind is light and cross-offshore. The water’s sitting at a normal 73° for this time of year. That morning window is actually looking very good, with clean surf on offer.
But don’t get too comfy. By Tuesday afternoon, the wind swings onshore and chops it right up, and that sets the tone for the next few days. Wednesday morning (August 26th) is a tease: a slightly bigger 5ft SW swell (1124 – moderate) with a lovely long 14-second period, and the wind goes glassy cross. It’s right on the edge of being good, but the guidance screams “marginal.” The standout for the whole window is actually Sunday morning, August 30th. We’ve got a 7ft WSW groundswell pumping in with an extra-long 18-second period (2363 – strong energy). The wind is a gentle cross-offshore breeze, making it clean. That’s the one to circle on the calendar if you’re an advanced surfer.
After that, it’s a real mixed bag. From August 31st right through to September 9th, the swell sticks around – mostly 6ft to 8ft from the SW or WSW – but the wind is constantly onshore, cross-shore, or just too strong. Some mornings like September 2nd and September 3rd show a clean cross-off window with 6ft to 7ft SW swell (around 1137-1712 – moderate to strong), but the rest of the time it’s choppy. By September 7th, the wind is howling at 28 mph, making a mess of the 6ft swell.
Honestly, for this 16-day stretch at Turtles, the real standout is that Sunday, August 30th morning session. It’s the cleanest combination of size, direction, and wind we get. The other clean mornings are there but the swell quality is often marred by questionable conditions.
Rusty.

Information about the Turtles Surf forecast
The above surf forecast table for Turtles provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Turtles can be found by selecting the local surf guide option on the grey menu. Our Turtles 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 (Turtles) 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 Turtles 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.
