The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking over the next couple of weeks at Turtles. This is a reef break, exposed to the swell, and it likes the swell coming from the SSW direction, which is exactly what we’ve got lined up for a lot of this run. The water is sitting at about 73°F, which is pretty much normal for this time of year, so nothing weird going on there.
The first real standout is on Tuesday morning, the 25th of August. We’ve got a clean 5ft SW swell with a 13-second period pushing in, and a light cross-off breeze from the SE at 6 mph. The energy’s moderate at 760, but it’s glassy and lined up. This is a proper session for the advanced crew – Turtles is no beginner wave.
Wednesday morning the 26th has similar size, 5ft from the SW, but the wind is a light cross-on from the NW at 3 mph. It’s still surfable for the experienced, but the energy is ramping up to 1124, so there’s a bit more punch. Thursday morning the 27th sees a jump to 10ft from the WSW with a 16-second period – that’s a long-period groundswell, and for a reef like this, it’s going to hold up and offer some real power. The cross-off wind from the SSE at 16 mph keeps it clean, but at that size, it’s strictly for experts. The energy is strong at 4533. The wind gets on it later in the day. Friday and Saturday are a bit messy with stronger cross-shore winds, so quality drops off.
Now, hold onto your boardies, because the best on offer is the Sunday morning of the 30th of August. Glassy conditions, a 6ft swell from the WSW, and a massive 18-second period. That’s a very long-period groundswell, perfect for Turtles. The energy is strong at 2024. This is going to be clean, powerful, and well-shaped. Absolutely the top pick for this forecast window. Monday morning the 31st is nearly as good – glassy again, 6ft, 16 seconds. Another cracker.
The first week of September is a bit of a mixed bag with onshore and cross-shore winds, but there’s still swell around the 5-7ft mark. The standout in the second week is looking at Tuesday morning, the 8th of September. A 7ft swell from the WSW with an 18-second period, gentle cross-shore wind, and strong energy at 3509. That’s another excellent prospect for the experts, a bit far out but promising. Wednesday the 9th also has a clean window with a 7ft W/SW swell.
So, to sum it up: Sunday the 30th and Monday the 31st of August are your absolute best bets – glassy, powerful, and long-period. Tuesday the 8th of September is a solid long-range lookout. Turtles can be a crowded spot, and it’s fairly consistent, so get in there when the winds are right. This reef delivers when it’s on, and for the advanced surfer, there are some proper gems in this run.
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.
