The Lowdown
G'day, Rusty here. Let's break down what's coming up over the next sixteen days. It's a bit of a mixed bag, but there's some real potential if you pick the right windows.
The main event is a solid, long-period groundswell from the WSW, but the wind is the real story. For the first week, the afternoons are getting hammered by strong southerly winds, making things lumpy and messy. You'll want to chase the morning windows when the wind is lighter and more offshore.
The standout is Saturday 29th August morning at Turtles, a reef break that's wide open to the swell. There's a clean 5ft swell from the SW, with a 12-second period. The energy is moderate (842), and the real key is the light SSE breeze at 9 mph, which is a clean cross-offshore wind. That's going to set up some really nice, clean lines. The water temp is 73°, which is about average for this time of year, so no surprises. Just be aware this spot can get crowded, and it's not one for beginners.
Before that, we have to grind through the early part of the week. Wednesday 26th August afternoon is a total loss – 7ft of swell with a strong onshore westerly wind, so don't even bother. Thursday 27th morning has a bit more size at 8ft from the WSW, and the wind is a clean cross-offshore, making it a possible session. That's a big, powerful wave (energy of 3858) with a 16-second period, so it's a proper groundswell, but it's only for the experienced crew. The afternoon gets messy again.
The next few days are much the same story: mornings offer cleaner conditions with moderate swell, but the afternoons get blown out. Sunday 30th August morning has a 6ft WSW swell (energy 2113) and a very long 17-second period, but the wind is a light cross-onshore, which is a bit of a letdown. It's still worth a look if you're keen.
Heading into the second week, the swell hangs in there but the quality drops. Monday 1st September morning looks clean with a 6ft WSW swell, but the energy is still solid. After that, the wind pattern stays tricky, with a lot of cross and cross-onshore conditions. There's a blip on Tuesday 8th September morning, with a 7ft SW swell and a 16-second period, but the cross-shore wind will put a chop on it. The long-range stuff is promising but less certain.
Overall, the clear winner is the Saturday morning session. It's clean, it's got a decent swell, and the energy is there. Get on it if you can.
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.
