The Lowdown
Alright folks, Rusty here with the skinny. We’ve only got one break in the sights, Turtles, a proper reef slab that’s wide open to the south swell. This spot is an advanced wave, and it needs everything to line up.
The first few days are scratchy. From Thursday the 3rd through Saturday the 5th, the swell is building but the wind is all over the place. You’ll get some clean morning windows, but it’s mostly lumpy and cross-shore junk. Not worth getting wet unless you’re desperate.
The first big call is Sunday the 6th. Big south groundswell at 10 feet, with a 13-second period, packing a ton of energy. The morning has a strong cross-offshore wind, so it’ll be clean, but that size is for experts only. The reef will be heavy and unforgiving.
Monday the 7th is a gem. The swell drops to 6 feet but the period stretches out to 17 seconds, making it a proper long-range groundswell. Clean offshore winds through the morning. The long period will make the waves stand up perfectly on this reef, with long waits between sets. The afternoon stays clean with 8-foot sets. A solid day for the experienced crew.
Tuesday the 8th and Wednesday the 9th stay clean in the mornings with offshore winds, but the swell is a bit smaller. Wednesday morning is a beauty: light offshore breeze, a clean 6-foot WSW swell at 16 seconds. Perfect conditions.
The absolute standout of the whole window is Thursday morning, the 10th of September. This is the one. A 6-foot WSW groundswell, very long 16-second period, and a near-glass cross-offshore breeze. The wave energy is strong, and it’s all coming together for Turtles to be world-class. Crowds are often a problem on days like this, so get down early.
The second week has some hits and misses. There’s a promising Monday on the 14th of September: clean offshore wind from the east, a solid 7-foot SW swell at 15 seconds, and plenty of energy. Another one for the experienced crew.
Don't bother with the afternoons – strong onshore sea breezes ruin it almost every day. Stick to the mornings, and you’ll get the good stuff.
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.
