The Lowdown
Hey, Rusty here. So we’ve got a solid stretch of swell hitting Turtles, but it’s not all going to be perfect. This is a reef break, very consistent, exposed to the southwest, and the water temp is about average for the time of year.
Starting Thursday, 20 August, morning – there’s a 2.5m SSW groundswell with a 16-second period, and the combined energy is at 3685 (strong to very strong). That’s a lot of power. The wind is cross-off from the SE at 20 km/h, keeping things clean. This is the standout of the first week – the morning session is the one to aim for. The afternoon wind picks up to 30 km/h, still cross-off, but a bit more breeze.
Friday, 21 August, morning is similar – 2.5m SSW swell, 17-second period, energy at 3774, and cross-off SE wind at 20 km/h. Still clean and powerful. But from Saturday, 22 August, the swell starts to drop – 2.1m on Saturday morning, then 1.7m by Sunday, and the energy falls into the 2000s. The wind stays cross-off but gets a bit stronger.
There’s a slow decline through the week, with the smallest surf around Wednesday, 26 August, where the swell is only 1.2m and energy is 735 (moderate). Thursday, 27 August, sees a small pulse back to 2.1m, but it’s not a standout.
After that, there’s a bit of a lull until Monday, 31 August, morning, when a 2.3m SW swell with an 18-second period and energy at 3788 shows up. Winds are cross-off from the SE at 20 km/h – that’s a promising long-range call, but it’s a week and a half away, so don’t lock it in just yet. The days after that slowly fade again.
So the best call is Thursday, 20 August, morning at Turtles – 2.5m, 16-second groundswell, massive energy, and clean cross-off winds. Crowds are sometimes around, so you might have some company, but the waves are worth it.
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.
