The Lowdown
Righto, gather round.
Let's talk Turtles. It's a pretty classic advanced reef set-up, wide open to the swell, and what we really want is that SSW direction to line up with its optimum. We've got a bit of a waiting game on our hands, though. The water is sitting at a balmy 72°, which is pretty much bang on average for this time of year—nothing weird there.
The next week and a bit is a bit of a frustrating watch. There's swell in the water, but the wind is a pain. Monday morning the 14th kicks things off with a solid 6ft of WSW swell at a very long 15 seconds (1742 combined energy), but that moderate cross-shore chop is putting a bit of a crinkle on it. That score is a bit of a tease. From Monday arvo right through to the end of Friday the 18th, it’s pretty grim. Fresh breezes and cross-onshore winds are just wrecking what could be decent waves. Tuesday the 15th has a clean 7ft on the charts, but 35 km/h cross-shore winds make for lumpy, ugly conditions. That's a no-go.
We finally get a flicker of hope on the morning of Saturday the 19th. It's not perfect, with a moderate cross-shore breeze and some chop, but the swell jumps to a heavy 10ft from the WSW at a very long 16 seconds (3684 combined energy). That’s a serious amount of water moving. It's a demanding wave for experts only at that size—definitely not for beginners, and probably a bit too much grunt for most on that reef.
The real standout, the one to mark on your calendar, looks like the morning of Thursday the 24th. It's a bit further out, so keep an eye on it, but the stars nearly line up. You’ve got a 7ft SW swell at a punchy 13 seconds (1729 combined energy) with a clean, cross-off wind. That’s the first time in a while we’ll see a proper wall. The afternoon gets messy again, but that morning window has "go" written all over it. Expect crowds, this one has a reputation.
After that, it's back to battling the onshores. Saturday the 26th packs a monstrous 10ft swell with a very long 19-second period (7282 combined energy), but with a strong 30 km/h cross-onshore wind, that's pure chaos and a hard pass for a paddle board. That one is kite-surf territory all the way. The last chance in the window is Monday morning the 28th. The swell drops back to 5ft (1294 combined energy) and the wind is just a light breeze, but it’s still cross-onshore. It'll be bumpy and a bit of a mission, but for the desperate and the skilled, there might be a few sneaky ones.
So, to be straight with you: this is a tough run for Turtles. The waves are there, but the wind is the enemy for most of it. Circle the 24th of September. That's your best bet for a clean session.

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.
