The Lowdown
Alright, let’s talk about Turtles. This is a heavy, advanced reef break that’s exposed to swell, and it’s got a real sweet spot for SSW groundswell. The water’s sitting at 73°, which is pretty much bang on average for this time of year, so nothing wild there.
The next few days are a bit of a write-off, honestly. Thursday afternoon kicks off with some lumpy 8ft swell but the wind is straight cross and the energy is massive at 3685, but it’s messy and not worth paddling out for. Friday morning cleans up a bit with a cross-off wind and still 7ft, but the forecast is marginal. Friday afternoon, Saturday, and Sunday morning are all compromised by onshore or strong cross winds, so you’re sitting on the beach for a bit.
Now, Sunday the 9th is where it starts to get interesting. The swell drops to 10ft but it’s a long-period SW groundswell, 17 seconds, with a clean cross-off wind. That’s a lot of energy — 5956 — and with that period, it’s going to be a proper, powerful groundswell. This is for experts only, no question. The reef will handle it well, but the sets will be long and heavy. Monday the 10th isn’t much chop, but Tuesday the 11th is another standout: 10ft to 12ft, SW, 15-16 seconds, and clean cross-off winds. The energy on Tuesday afternoon hits 6861, which is serious. Still, you’re looking at a clean, heavy, expert-only session.
The real gem, though, is Thursday the 13th in the morning. The swell drops to 6ft, but it’s a long-period SW groundswell at 15 seconds, and the wind goes offshore from the east at 15 mph. That’s the kind of glassy, clean, lined-up condition that makes Turtles a dream. The energy is moderate at 1457, but the quality will be there for experienced surfers. That’s your best window.
After that, the swell stays around 6ft to 7ft through the weekend, but the winds start to mix up. Sunday the 16th morning is worth a mention: 5ft, clean, light offshore from the east, and 869 energy — not huge, but clean and fun. The 18th brings a bigger 10ft pulse, but it’s cross-shore and lumpy, not ideal.
Bottom line: if you’re good enough, Sunday the 9th and Tuesday the 11th are the big-wave days, but Thursday the 13th morning is the pick of the bunch for clean, quality reef surf. Stay sharp, Turtles doesn’t forgive mistakes.

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.
