The Lowdown
Alright, this is Rusty comin' at ya from the Turtles line-up.
We’ve got a solid window of swell ahead, but it’s not without its shifty moments. The long-range picture is a proper groundswell train, but you’re gonna have to pick your windows carefully. This is a spot for the experienced crew only, and with the size we’re seeing, it’s not the place for a learner.
The first real action hits on Sunday the 9th. It’s a bit of a frantic start, with a solid 10 ft SW groundswell, and a 17-second period. That’s proper long-period energy, the kind that wraps around the reef with serious power. The combined energy is a massive 5977, which is very strong. But the wind is howling from the SE at 19 mph, making it a cross-off breeze. It’ll be clean, but it’s angry out there. The tide conditions are questionable, so it’s gonna be a battle. That swell is over 8 ft, so this is strictly for the experts.
Monday the 10th is the standout. The swell drops a touch to 7.5 ft, still from the SW, but the period is still a very long 15 seconds. The morning has a gentle SSE breeze at 9 mph, giving us a clean cross-off. The energy is still very strong at 3045, and the forecast says the conditions are excellent for experienced surfers. This is the pick of the whole run. The water temp is about average for this time of year, so a 4/3 is a good idea.
The back half of the first week gets messy. Tuesday the 11th sees a drop in swell to 3.3 ft in the morning, but it jumps back to 8.2 ft in the afternoon with a strong 22 mph cross-off wind. The energy is still strong at 3335. Wednesday the 12th morning is a real highlight for the dedicated: an 8.2 ft SW swell with an ESE wind at 19 mph, giving us a full offshore breeze. The energy is strong at 3136, and it’s fresh offshore and clean. That’s a good session, but again, it’s big. The rest of the week is a mix of clean mornings and chop-filled afternoons, with the swell slowly easing.
The second week starts to get more interesting again. On Sunday the 16th, a clean morning with a 5 ft SW swell, a 14-second period, and a glassy ENE breeze at just 3 mph. The energy is moderate at 828. The forecast says to expect very good surf conditions. That’s a sweet spot for a longboard or a funshape.
We get a pulse of energy again around the 18th and 19th, with 10 ft and 8.2 ft swells, but the wind is a mess, mostly cross-on or cross-off with some strong breezes. The 19th morning is clean with an 8.2 ft swell and a 16-second period, but the energy is very strong. It’s a gamble.
The last four days of the run, from the 21st to the 24th, settle down. The swell drops to a consistent 5 ft to 6 ft from the SW, with periods around 14-15 seconds. The winds are manageable, mostly light to moderate cross-off breezes, with a few clean mornings. The 23rd morning is a beauty: a 5.6 ft SW swell, 14-second period, and a light S wind at 6 mph. The energy is 1220, and the conditions are excellent for experienced surfers. It’s a far more relaxed end to the run.
Overall, the best on offer is the Monday morning, the 10th of August. That’s the one to circle. The Wednesday morning of the 12th is a close second for the hardcore. The Sunday morning of the 16th is a great option for a smaller, cleaner session. The 23rd morning is a solid, consistent finish.

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.
