The Lowdown
Alright, mate, Rusty here. Let’s have a proper look at what’s coming down the line for Turtles. It’s a bit of a mixed bag, so let’s wade through it.
The immediate forecast has us waiting for the ocean to get its act together. We’re looking at a few days of messy, wind-affected surf before the conditions we actually want show up. For the first stretch, from Thursday the 10th through the middle of next week, the swell is there, but the wind is going to make things proper ugly. We’ve got moderate to fresh cross-onshore breezes chopping things up, and the odd strong one on the weekend. There will be waves, but they’ll be lumpy and hard to love. You’d be fighting it more than surfing it.
Now, looking ahead. The standout window is the morning of Thursday, the 17th of September. This is where things click. The swell drops slightly to about 6ft from the WSW, but the wind swings around to a light offshore from the NNW. The water is going to be glassy. This is a proper clean session on an advanced reef, so you’ll need your wits about you, but the quality will be there. The energy is strong. It's a window you don't want to sleep through.
Then, into the following week, we’ve got another interesting one. The morning of Friday, the 25th, looks clean again with a cross-offshore breeze. The swell is smaller, around 3ft, but it’s coming from the west with a long 20-second period. That’s some proper groundswell energy traveling a long way, and it’ll wrap in nicely. It’s a good call for a longboard or a step-up in the quiver.
There’s a big bonk of swell on Sunday the 20th – pushing 10ft – but the wind is onshore and the period is short, so it’s going to be a serious, unruly mess. That’s expert-only territory, and even then, it’ll be challenging. For anyone else, it’s a day to watch from the cliff.
The first few days will be a write-off, a good time to get the gear sorted. But that Thursday morning the 17th, and that Friday the 25th, are the ones to circle. They’re not certainties this far out, but they’re bloody promising.
Alright, stay sharp.

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.
