The Lowdown
Alright, Rusty here, let's talk about what's shaping up.
We've got a solid run of surf coming through for the region, centered on Turtles, a solid advanced reef break. The water's sitting at 73°F which is about normal for this time of year, so no surprises there.
We kick off on Friday, the 28th of August. It's not a great start – there's wind and lumpy conditions with a 8ft SW swell, so the morning is the better bet of the two sessions, but it's still marginal. Saturday the 29th is much the same story; a dropping swell but still bumpy.
Now, Sunday the 30th of August is where it gets exciting. We've got a 6ft WSW groundswell rolling in with a long, juicy 17-second period, and the wind is glassy in the morning, straight out of the WNW. That's the standout session of the first week. This is a reef break, so that long-period energy is going to unload nicely, though for the advanced crew only. The combined energy is pumping at 2089 – that's strong stuff. If you can surf Turtles, Sunday morning is the one. The afternoon turns onshore, so be out early.
Monday the 31st and Tuesday the 1st of September see the swell drop slightly and the wind turns cross and cross-on, making things choppy. Not ideal. Wednesday the 2nd and Thursday the 3rd are cleaner in the mornings with cross-off winds, but the swell is smaller at 5ft to 5ft. You'll find some corners, but it's not firing.
We hit a rough patch from Friday the 4th through Saturday the 5th – strong winds and messy seas. That Sunday the 6th of September morning has a big 10ft WSW swell and clean cross-off winds, but it's a beast. Combined energy is 3955 – very strong. Only for the experienced and confident. The morning looks clean, but the afternoon gets shredded by cross-wind.
Monday the 7th and Tuesday the 8th of September are smaller again and cleaner in the mornings, but nothing to write home about. Wednesday the 9th is onshore and choppy.
Then, we get a late pulse. Thursday the 10th of September delivers the biggest swell of the whole period: an 12ft WSW groundswell with an 18-second period. The combined energy is a massive 7515 in the morning, and 7890 in the afternoon. This is a giant, powerful groundswell. The morning has a gentle cross-shore breeze with just a slight chop, so that's the cleanest window for the big stuff. This is for experts only – this is a serious, heavy wave. Friday the 11th has a similar 12ft swell in the morning with clean cross-off winds, but the afternoon is blown out.
Overall, your two absolute standouts are Sunday morning, August 30th for the clean, glassy 6ft wave that's still meaty, and Thursday morning, September 10th for the massive, clean, long-period groundswell. The big one on the 10th is a promising but less certain call this far out, but if it comes together, it'll be the session of the month.
Stay safe out there.

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.
