The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for Turtles over the next couple of weeks.
The pattern is a solid, drawn-out run of southwest groundswell, but the wind is the real story here. For most of the first week, it’s going to be a battle with onshore and cross-onshore breezes, which will mess up the surface. The water temp is sitting at 71°, which is bang on average for this time of year, so nothing unusual there.
We kick off on Wednesday the 9th. There’s a strong 7ft SW swell with a 16-second period, packing a punch with combined energy of 2183, but the wind is a fresh 19 mph easterly. That’s offshore, so the face will be clean, but the conditions are marginal and the tide might be a factor. It’s an advanced wave, so only for the experienced crew.
Thursday morning the 10th looks a bit better. The swell drops slightly to 6ft from the WSW, period still a solid 15 seconds, and the wind turns light ENE at 6 mph. That’s cross-offshore and clean. This is a standout window for the experienced surfer, with excellent conditions and combined energy still strong at 1399. The afternoon on Thursday, however, goes downhill fast with onshore wind and choppy surf.
Friday the 11th is a write-off with poor conditions, and Saturday the 12th brings a bigger but messier 7ft swell with cross-onshore wind. The morning of Sunday the 13th has a light cross-onshore breeze, but it’s still only marginal.
The long-range stuff gets interesting. Thursday the 17th morning is a gem. The swell is 5ft from the SW with a 15-second period, and the wind goes glassy – WNW at just 3 mph. Combined energy is 1054. That’s a clean, glassy session for the advanced surfer, and a real standout. The forecast is close enough to trust.
After that, the swell drops off Friday the 18th, then we get a big pulse on Saturday the 19th with 12ft of WSW swell, but it’s blowing 22 mph onshore. That’s a total mess – too big for most anyway, and the wind will make it a washing machine. The combined energy is a massive 5163, but it’s only good for the very strong, experienced crew, and the conditions are poor.
Sunday the 20th morning offers a slight reprieve with a 8ft WSW swell and a fresh 19 mph cross-offshore breeze, so it’s clean, but the energy is huge at 2990. Monday the 21st morning brings a 8ft SW swell with a 16-second period, light southerly cross-shore, and combined energy of 3200. That’s a solid, powerful groundswell, but again, it’s a big wave for experts only.
The last few days, from the 22nd to the 24th, see the swell still pumping, but the wind is mostly onshore or cross-onshore, keeping the quality down. The best chance is to pick those early morning windows when the breeze is lighter, like Wednesday the 23rd morning, but it’s still a gamble.
Overall, if you’re an advanced surfer, the standout is Thursday the 17th morning for that glassy, clean 5ft swell. For a bit more power, Monday the 21st morning offers a solid 8ft groundswell, but you’ll need to deal with some cross-shore wind. The rest of the run is a fight with the wind, so pick your sessions carefully.
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.
