The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way for Turtles. This is a serious stretch of swell, no doubt about it, but we’ve gotta work for it with the wind. We’re talking about an exposed reef break that’s strictly for advanced crew—this isn’t the place to be learning.
We kick off the outlook with a massive pulse. Monday the 7th has a solid 10ft of SSW groundswell rolling in with a very long 17-second period. The combined energy is massive at 4856. The trouble is the morning wind is a fresh 19 mph from the SSE, which is cross-offshore and keeping things clean, so it might be worth a look for the brave. But the same day in the afternoon, the wind swings S and picks up to 25 mph, which is a strong cross-shore breeze, making a mess of it.
Tuesday the 8th and Wednesday the 9th drop back slightly to 7ft to 8ft, still good SW swell with long periods of 15-16 seconds, but the wind is a persistent fresh breeze out of the SE and ESE. That’s a cross-offshore flow, which will hold the surface together, but it’s not true offshore. The water temp is sitting at 72°, which is bang on average for this time of year, so no surprises there.
Now, keep your eyes on Thursday the 10th. That morning is the standout of the entire first week. We get a glassy session—wind from the ENE at just 3 mph, making for perfect conditions. The swell is still 6ft from the WSW with a 15-second period, and the energy is 1397. That is going to be absolutely clean, lined-up reef waves for the experienced surfer. Get on it.
From Thursday afternoon onwards through the weekend and into the next week, the wind shifts onshore or cross-shore, and the conditions get lumpy and choppy. The swell remains in the 4ft to 8ft range, but the quality is poor. There’s a bit of a pick on Saturday the 12th morning with a light onshore breeze and a 7ft swell at 17 seconds, but it’s far from ideal.
We get another big pulse around Monday the 21st and Tuesday the 22nd. Monday morning sees a beast of a swell at 12ft from the WSW with an incredibly long 19-second period, energy at 9562. This is a very powerful, very long-period groundswell—absolutely serious. On a reef like Turtles, that’s going to be heavy. The wind is a moderate cross-onshore, so it won’t be perfect, but the energy is undeniable. This one is only for experts, and it’s a promising but less certain call way out there.
If you’re not an advanced surfer, stay well clear of Turtles when it’s over 8ft, which is most of this run. The setup looks more interesting for kite surfing than paddle surfing on many of the windier afternoons.

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.
