The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way.
We’ve got a long run of waves on the cards, but this isn’t a straight-up beginner’s paradise. The standout spot is Turtles, a proper reef break. The water’s sitting at 73°F with a water temperature anomaly of 0.7°C—so about average for this time of year. Right out of the gate on Sunday the 30th of August, we’ve got a solid 6ft swell from the WSW with a long 17-second period. However, with that cross-on wind and a combined wave energy reading of 2089 (moderate to strong energy), it’s looking a bit bumpy, nothing special.
Monday the 31st carries on with similar 7ft swell, but the wind stays tricky and the conditions are just marginal. Tuesday the 1st of September morning is where it starts getting interesting. The swell drops slightly to 6ft from the WSW, period still a long 16 seconds, but we finally get a clean cross-off wind and a wave energy of 1687. That’s proper, clean reef surf for the experienced crew.
Wednesday the 2nd and Thursday the 3rd stay in the small-to-medium 5ft to 5ft range, but the wind plays up again, keeping quality down. Friday the 4th of September morning cleans up once more with a 6ft SW swell and a light cross-off breeze—decent but not a standout.
Now, the real highlight. Monday the 7th of September is the one to circle. We’re looking at a solid 10ft swell from the WSW, a very long 17-second period, and an offshore wind from the ESE first thing. The combined wave energy is huge at 5170 (very strong). That’s a serious, heavy groundswell at a reef. This is for experts only—8ft+ is big, and that long period will make it wall up. Come the afternoon, the wind goes cross-off from the SE, and it’s still clean with 10ft and 16 seconds. That’s the pick of the whole outlook.
Tuesday the 8th of September is still pumping with 8ft WSW swell, period 16 seconds, and a cross-off wind in the morning from the NE. The energy is still very strong at 4025. Another day for the experienced surfer.
After that, the swell backs off a bit. We get a lovely, glassy morning on Thursday the 10th of September. Only 6ft, but with an ENE breeze so light it’s flat calm—glassy conditions and a 16-second period. Beautiful, clean lines on the reef.
The final days into the second week show smaller swell and more onshore winds. The last notable mention is Monday the 14th of September morning, with 6ft from the WSW, 15 seconds, and a clean offshore from the ESE. A solid end to a long, active period.
Don’t come here expecting mellow waves. Turtles is an advanced reef that can get very heavy. If you’re not ready for a 10ft groundswell with strong energy, sit this one out. But for the crew who are, the 7th and 8th of September are the real deal.
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.
