The Lowdown
G’day, Rusty here. Alright, let’s have a look at what’s coming up for Turtles. This is a solid, exposed reef break that’s gonna see some serious size roll through over the next couple of weeks, but the wind’s gonna be the main character here, and it’s not always a friendly one. The water’s sitting at a pretty normal 71.8°F for this time of year, so nothing weird going on there.
It kicks off Sunday the 6th, but honestly, it’s a write-off. A 25 mph southerly cross-breeze is smashing into a 13.1ft SW swell with a moderate 12-second period, and the combined energy is a massive 4850 (strong). It’s just messy, blown-out, and ugly. Not a wave you want to paddle into. That hangs around through Monday the 7th with a 9.8ft SW swell and a super long 17-second period, but that 19 mph SSE cross-off wind at least cleans it up a bit – still, the energy is huge at 5248, and with the size, it’s really only for the brave. The afternoon goes back to messy.
Tuesday the 8th through to Wednesday the 9th sees the swell drop a little, 7.5ft to 6.6ft, still a long 16-second period from the SW. The wind is a cross-off, so it’s clean, but the swell is still packing a punch (wave energy 2634 down to 1982). It’s surfable, but not what I’d call firing.
Now, here’s where it gets interesting. Thursday the 10th morning is the first real standout. The swell drops to a more manageable 5.9ft from the WSW, still a nice 15-second period, but the wind goes light and variable from the NE at 6 mph, making conditions clean. The wave energy is down to 1600 (moderate). This is excellent surf for experienced surfers – clean, good lines, that reef will be working. But look, by the afternoon the wind swings onshore from the west, so get on it early.
Friday the 11th is a write-off again with messy onshore winds, so don’t bother.
Now, Saturday the 12th – this is the best of the whole run. The swell bumps back up to 6.2ft from the WSW, still a very long 17-second period, which means powerful, clean lines. And the wind? Glassy. A 3 mph NNW breeze, so it’s flat calm. The wave energy is high at 2478 (strong). This is the session to circle. The reef will be handling that long period beautifully, and with no wind, it’ll be as clean as it gets. Crowds are often here, so you’ll have company, but for that quality, it’s worth it.
Sunday the 13th to Tuesday the 15th is a bit of a mixed bag. The swell holds around 6.2ft to 6.9ft, but the wind is cross or cross-on, so it’s lumpy. The mornings are better, but the afternoons get blown out.
Wednesday the 16th morning is another nice window. The swell is down to 4.9ft from the SW, 13-second period, and the wind is a light cross-off from the SSE at 9 mph. Clean conditions, moderate energy (1216). Good for a paddle.
Then the end of the run gets big again. Friday the 18th and Saturday the 19th see a big pulse of 9.8ft to 11.5ft WSW swell, with the wave energy jumping to 5046 and 5394. That’s strong, heavy, and with a 16-second period, it’ll be a proper beast. The wind is a fresh cross-shore, so it’s lumpy and powerful. This is only for experts, no question. It’s a full-on challenge.
Sunday the 20th morning cleans up a bit with a lighter cross-off, but the swell is still a solid 9.8ft. Then the run fades out through Monday the 21st with dropping swell and a return to lumpy, onshore afternoons.
So, the standout is clear: Saturday the 12th September. Glassy conditions, 6.2ft WSW swell with a long 17-second period – that’s a dream session at Turtles. The second option is the morning of Thursday the 10th September – a bit smaller at 5.9ft, but clean and light winds. Get in the water.

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.
