The Lowdown
Alright folks, Rusty here, and I’ve been peering at the charts for the next stretch. The only game in town for the whole 16 days is Turtles, a solid reef break that’s fairly consistent. The water is sitting at 73°, which is pretty much normal for this time of year, so no surprises there.
The action kicks off on Thursday, 27 August, but it’s a bit of a mixed bag. Thursday morning has rain showers with a cross-off wind from the SSE at 16 mph, and the swell is a solid 8 ft from the WSW at a very long 16 seconds. The combined energy is pumping at 3834, which is strong. But the wave comment says it’s marginal, and with that size, it’s a big wave for advanced surfers only. That afternoon, it gets worse—cross-shore wind at 19 mph and lumpy conditions. Friday and Saturday are similar, with clean-looking mornings but winds that are just too strong to make it truly good. Saturday morning’s 5 ft SW swell with a gentle 9 mph cross-off is the best of a weak bunch.
Now, here’s the standout. Sunday, 30 August, morning is where it’s at. The wind drops to zero—dead glassy—and the swell is 6 ft from the WSW at a very long 17 seconds. The combined energy is 2113, moderate to strong, and the comment says “excellent surf conditions for experienced surfers.” That’s the one. A true groundswell, long period, and offshore winds mean Turtles will be firing clean. Just be aware that with that long period, it might break a bit too straight for some, but on a reef, it’ll be a gem. Crowds are often a thing here, so get in early.
Sunday afternoon goes onshore, and Monday morning holds a 7 ft WSW swell but with a light cross-on wind, making it marginal. The rest of the week sees a slow decline in swell size, with most afternoons getting chopped up by strong breezes. There’s a bit of a gap in quality after the first few days, with nothing really standing out until the following week.
On Sunday, 6 September, the morning brings a glimmer of hope. The wind is offshore from the east at 6 mph, with a 5 ft SW swell at 14 seconds. The combined energy is 1011, moderate, and it’s clean. That’s another good session for experienced surfers, but it’s not as strong as the previous Sunday. After that, the swell drops further, and by Monday, 7 September, it’s down to 3 ft, with the rest of the 16 days fading into small, choppy conditions.
So, in short: if you’re after the best, make a beeline for Turtles on Sunday, 30 August, morning. That glassy, long-period SW swell will be a treat. The following Sunday, 6 September, is also worth a look for a cleaner but smaller session. Everything else is either too windy, too lumpy, or just marginal. Stay sharp, and keep an eye on the forecasts.
Rusty, signing off.

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.
