The Lowdown
Alright folks, Rusty here. Let’s talk about what’s coming up at Turtles.
This is an advanced reef break that needs a solid SSW swell to get going, and the next couple of weeks look like a slow burn before things get really interesting. The water temp is sitting at 74°, which is about normal for this time of year. Don’t expect much to start – the first few days are a write-off with messy winds and marginal surf. The real waiting game begins now.
Thursday morning the 16th has a 4ft swell from the WSW, but that 25 km/h NNE breeze is cross-off, so it’s clean but not really packing enough punch or direction. The energy is moderate (913). It’s a one-star kind of day, honestly. That afternoon and Friday get worse as the wind swings onshore. Saturday the 18th sees a bit more size, 6ft in the morning from the WSW, with a light N breeze making it cross-shore and a bit bumpy. The energy jumps to 1271, but the tide or conditions are questionable. Not the one.
Now, Sunday the 19th is where you should start paying attention. You’re looking at an 8ft WSW groundswell with a 15-second period, which is a long-period groundswell, meaning better shaped waves but longer lulls. The wind goes glassy in the morning – 5 km/h from the east. That’s dead calm, clean, and beautiful. The energy is strong (3037). This is for experienced surfers only; it’s too big for beginners. The break is fairly consistent here, and crowds are often, so be prepared to share. This is the standout of the first week.
The next few days drop off into the 4ft to 6ft range with onshore winds, not worth paddling out for. The end of the week on the 23rd has a Thursday afternoon window with 5ft from the SW, 15-second period, and a gentle offshore breeze from the east. Clean, smooth, excellent for experienced surfers. Energy is moderate (1001). That’s a solid pick for a relaxed session.
The following week is quieter, with mostly small swell and clean but weak conditions. The 26th Sunday morning has 4ft from the WSW, 14 seconds, and a light NNE breeze that’s cross-off and clean. Energy is moderate (984). It’s a decent morning if you’re desperate.
But the real standout in the second week is Friday the 31st. Mark that one. A 6ft WSW groundswell with an 18-second period – very long period, which means powerful, well-shaped waves that will hold up nicely on this reef. The wind is completely glassy. Zero. Calm. That’s rare. The energy is strong (2120). This is another one for the experienced crew, but it could be the best session of the whole outlook. Promising, but it’s a long way out, so keep an eye on it.
Overall, don’t bother paddling out until Sunday the 19th. The two true standouts are that Sunday morning and the final Friday. Everything else is either too small, too windy, or just average.
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.
