The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way.
We’ve got a solid run of swell on the radar for Turtles, but it’s not all good news. The water temp is sitting right around 73°, which is only a touch warmer than normal for this time of year, so nothing to get excited about there. The real story is the size and the wind. This is a reef break that demands respect, and with the size we’re looking at, it’s going to be for the experienced crew only.
The first few days are a bit of a write-off. Friday the 7th is a tease with a clean 7ft swell from the WSW, but it’s a cross-off wind and there’s a 16-second period which is nice, but the surf is just marginal. Saturday the 8th is a total loss with strong winds and messy, lumpy conditions. Not worth paddling out.
Sunday the 9th is where it starts to get interesting. That morning, we have a 10ft swell from the SW with a very long 17-second period and a clean cross-off wind from the SE. The combined energy is massive (5743), so there’s a lot of power in the water. The afternoon cleans up even more as the wind drops to a moderate breeze. This is a solid window for the experts.
Monday the 10th is a mixed bag. The morning is OK with a cross wind and a 8ft swell, but it gets messy in the afternoon. Tuesday the 11th is a big one. The morning has a 10ft swell with a strong 28 mph cross-off wind, but it stays clean. The afternoon is even better, with the swell bumping up to 12ft from the SW, a 16-second period, and the combined energy hitting 6522. That’s a lot of water moving around.
Now, the standout of the entire run is shaping up for Wednesday morning, August 12th, and Monday morning, August 17th. The 12th sees a 10ft SW swell (16-second period) with a true offshore wind from the ESE at 22 mph. That’s a clean, powerful wave for a reef break. The 17th is even more promising for the long-range crew: a 10ft WSW swell with a 17-second period and a light 6 mph cross-off wind from the NNE. The combined energy is 4774, and the conditions are clean. This is the one to circle on the calendar, but it’s a long way out, so keep an eye on it.
There’s a few other windows, like the morning of the 13th and 14th, with offshore winds and 7ft to 7ft swell, but the wind is a bit stronger. For the rest of the run, it’s a mix of lumpy onshore and cross-shore winds, but the 17th is the one that’s got my attention.
Stay safe out there, this is a reef break for the experienced.
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.
