The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a solid run of south-west groundswell lining up for Turtles, and it’s looking like a proper run of quality waves for those who know what they’re doing. The water’s sitting at 73°, which is pretty much spot on average for this time of year, so no surprises there.
The first real sniff of action comes Monday morning, 27 July. It’s a bit on the smaller side with 3ft from the WSW, but the period is a long 15 seconds and the wind is cross-off from the ESE at 12 mph, keeping it clean. The energy is moderate (534). It’s a bit marginal though, so I wouldn’t rush for it.
Tuesday morning, 28 July, is where we start to get a little more interesting. Swell bumps up to 6ft from the SW with a 13-second period, and we’ve got offshore wind from the East at 12 mph. Clean, lined up, and the energy is climbing (987). This is a solid morning session.
Now, Wednesday morning, 29 July, is a standout. The swell holds at 5ft from the SW, 14-second period, but the wind goes glassy-light from the NNE at just 3 mph. That’s cross-off, clean, and the energy is ramping up strong (1318). The report says it’s excellent for experienced surfers, and I’d agree. This is the pick of the first week.
Thursday morning, 30 July, still has clean 5ft SW swell with a long 16-second period and cross-off SSE wind at 9 mph. Energy is solid (930). Good, but not the peak.
The weekend of 1-2 August sees the swell size climb. Saturday morning, 1 August, is 7ft from the WSW, 16-second period, and cross-off SE wind at 16 mph keeps it clean. The energy is now strong (2372). It’s getting big, but for advanced surfers, this is a proper window. Sunday morning, 2 August, delivers 7ft SW swell, 15-second period, and a clean offshore from the ESE at 16 mph. Energy is very strong (2027). This is a top-tier morning for the crew who can handle it.
The next big standout is Monday morning, 10 August. Swell is a solid 10ft from the SW, 14-second period, with a fresh offshore from the ESE at 22 mph. The energy is huge (3261). The afternoon is even better, with the same 10ft but a cleaner offshore and the energy hitting 3644. This is only for experts, but it’s a serious session.
And then Tuesday morning, 11 August, might just be the best of the whole run. 10ft from the WSW, a very long 17-second period, cross-off from the NE at 16 mph, and the energy is absolutely pumping at 5714. That’s a big, powerful, clean groundswell. The afternoon is onshore and messy, so the morning is the window. This is a long-range call, so it’s promising but not locked in yet.
Keep in mind, Turtles is a reef break, and it’s fairly consistent. It’s an advanced wave, and with that long-period groundswell, it’ll be breaking with a lot of power. The crowds are often there, so get in early. The SW swell direction is right on the money for the optimum here.
There’s a big gap from Wednesday 5 August through to Sunday 9 August where the wind is mostly cross-on or onshore, making it messy. Surfable, but not the quality you’d bother with unless you’re desperate.
Stay safe, read the swell, and I’ll see you in the water.
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.
