The Lowdown
Alright folks, Rusty here with the outlook for Turtles. This is a reef setup for advanced crew only, mainly getting a solid run of SSW to WSW groundswell. We’ve got some decent pulses coming through, but the wind is going to make or break the sessions.
Overview & Water Temp:
The water temp is sitting around 73° right now, which is about 1° warmer than usual—basically normal for this time of year.
Monday 24 August:
Not a great start. Morning has clean conditions with a 6ft swell from the WSW, but the energy is strong at 1428. The score is too low to get excited about, with marginal conditions flagged. Afternoon turns into a total mess with strong onshore winds and lumpy surf, so just skip it.
Tuesday 25 August:
A slight drop in size. Morning has 5ft from the SW with clean conditions, but it’s still not a standout—energy is down to 767 and it’s marked marginal. Afternoon is blown out again.
Wednesday 26 August:
This one teases us. Morning has offshore wind with 5ft from the SW and solid energy at 1126 (clean conditions), but it’s still rated as marginal. The afternoon sees a jump in swell to 7ft from the WSW with very high energy at 2909, but onshore wind and lumpy conditions ruin it.
Thursday 27 August:
The swell builds big. Morning shows 10ft from the SW with massive energy at 4451 (clean conditions), but it falls into the marginal category. This is big for most—definitely too big for beginners and pushing expert territory. Afternoon has 25 mph crosswind and messy chop. Not the one.
Friday 28 August:
Swell drops a bit. Morning is 7ft from the SW with 1902 energy, clean but still marginal. Afternoon is 6ft, clean, but still rated low. It’s there, but not firing.
Saturday 29 August – The Standout:
This is the pick of the period. The morning has fresh 19 mph offshore winds from the ESE with a 4ft SW swell. Energy is moderate at 506. Conditions are clean, and it’s marked as marginal—but the offshore wind at Turtles is a big deal. This is a rare chance for glassy, draining waves on a fairly consistent reef. Afternoon fades to a tiny 2ft from the WSW with a very long 21-second period, giving 601 energy—clean, but just too small to get excited about.
Sunday 30 August:
Morning has 6ft from the WSW with strong energy at 1944 and clean conditions, but it’s still a marginal call. Afternoon turns onshore.
Monday 31 August:
This is the second real standout. The morning is excellent for experienced surfers: 6ft from the WSW, 16-second period (groundswell), with 1718 energy and light offshore/cross-off winds at 6 mph. This will be clean and powerful—perfect for Turtles’ reef. Afternoon gets choppy again.
Tuesday 1 September:
Morning holds: 6ft from the WSW, 16-second period, 1859 energy, clean with moderate breeze. Still marginal but a decent session.
Wednesday 2 September to Sunday 7 September:
A mixed bag of moderate swells (5ft to 7ft) but most afternoons are blown out or lumpy. The morning of 7 September brings a 10ft SW swell with 3003 energy and clean conditions—rated a 4, which is the best score in the entire run—but that’s big wave territory, expert only.
Monday 7 September (full day):
Morning as above: big, clean, powerful. Afternoon gets cross-choppy.
Tuesday 8 September:
Last day to check. Morning has 7ft from the SW with 1291 energy, clean, but the period drops to 12 seconds. Still marginal.
Bottom line: The real window is Saturday 29 August morning with offshore winds and Monday 31 August morning for excellent conditions on a nice groundswell. The 7 September morning is huge and clean (energy at 3003), but only for the brave. Crowds are likely at this spot, so expect plenty of company when it’s clean.
Keep an eye on those windows. Rusty out.

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.
