The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for Turtles.
The pattern over the next 16 days is a bit of a mixed bag. We’ve got plenty of size on the charts, but the wind is the real story here. It’s going to be a classic case of waiting for the right moment. The first few days are a write-off, so we’ll be sitting on the beach for a bit. From Monday 24th right through to late Tuesday 25th, the conditions are either poor or marginal, so don’t even bother paddling out until we get a proper window.
The first real standout comes on Wednesday morning, 26th August. This is the one to circle. The wind goes glassy, dead calm from the WNW at just 3 mph. The swell is a solid 5 ft from the SW, and it’s a long-period groundswell at 14 seconds. That’s going to produce some proper, well-shaped lines. The combined energy is pumping at 1124 (moderate), and the water temp is sitting at 73°, which is about normal for the time of year. Turtles is an advanced reef break, and with that kind of clean, glassy surface, it’s going to be world-class for the experienced crew. This is your best bet early on.
We’ve got another promising window for the experienced surfers on Sunday morning, 30th August. The swell is 7 ft from the WSW, with a very long period of 19 seconds, bringing a ton of energy (2747, strong). The wind is offshore from the east at 9 mph, which should keep things clean. That long period swell will be holding up nicely on the reef. Expect some serious power.
Then again on Monday morning, 31st August, we see a 7 ft WSW swell at 16 seconds with light cross-offshore winds from the SE at 6 mph. The energy is strong at 2033, and the conditions are clean. This is another solid option for the advanced lads.
Looking further out, the second week has a couple of notes. On Saturday morning, 5th September, there’s a 7 ft WSW swell with clean cross-off winds, but it’s marginal. On Sunday morning, 6th September, we get another glassy window with a 7 ft SW swell and a 14-second period. The wind is glassy from the NNW at 3 mph, and the energy is strong at 1930. This one is promising, but it’s a long way out, so don’t lock in the plans just yet.
Overall, the best of the best is that Wednesday morning, 26th August session. Glassy, clean, and a solid SW groundswell. For the experts, the Sunday 30th August morning also looks like a cracker.
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.
