The Lowdown
Alright, Rusty here, let's look at what's on the table.
Alright, we’ve got some serious energy building for Turtles, a reef break that's for advanced crew only. For the next couple of weeks, it’s all about Turtles, but you’ve gotta pick your moments. The first few days have some cleaning up to do, but there's a real standout on the way.
The water temp is sitting at a pretty standard 72.9°F, so nothing wild there for this time of year.
Saturday the 29th is a write-off with cross-onshore winds, save your energy. Sunday the 30th morning is where it gets interesting. The wind goes totally glassy, zero km/h, with a solid 6.2ft swell from the WSW. The period is a very long 17 seconds, bringing in some proper groundswell energy (2089). This is the real deal, but at that size and with a very long period on a reef, it's a serious wave for experienced surfers only. The afternoon gets a bit messy with the cross-onshore.
Monday the 31st morning is a chance with clean, light cross-shore winds and a 6.6ft swell from the WSW, still a very solid 16-second period (2345). Again, this is powerful stuff for the skilled crew.
Then we hit a bit of a lull in quality. Tuesday the 1st through to Thursday the 3rd of September are all looking marginal with moderate to fresh cross-shore winds chopping things up.
Now, look at Friday the 4th of September morning. We get a cleaning breeze again, cross-off from the SSE, with a 6.6ft SW swell, period 14 seconds (1429). It's a decent window of clean surf.
Saturday the 5th and Sunday the 6th of September are blown out with strong winds, not worth it.
Monday the 7th of September morning is a real highlight on the horizon. Offshore wind from the East, 25 km/h, with a 5.2ft SW swell. The swell period is a solid 13 seconds (1061), and that offshore flow will be magic for the take-off. For a reef break, a clean offshore wind is gold. It’s a bit more manageable size, but that wind will make it world-class for those who can handle the reef.
Tuesday the 8th of September morning is also clean with a cross-off breeze and a 6.2ft SW swell, 16-second period (1737). Another solid option.
The following week keeps the swell alive but the winds are trickier. Another real standout appears on Thursday the 10th of September morning with clean cross-off winds and a 6.9ft WSW swell, 15-second period (2152). That’s a powerful, clean morning for the experienced.
And looking way out, Saturday the 12th of September morning and Sunday the 13th of September morning are beautiful. Saturday has a 6.2ft SW swell with clean, gentle cross-off winds (1349). Sunday the 13th morning drops to a 3.0ft WSW swell, but with an offshore East wind, a very long 19-second period (1262) and clean conditions. That's a little gem for the advanced surfer who wants a fun, clean wave on the reef.
So, the best of the best? Sunday the 30th of August morning with that dead glass and solid, long-period groundswell is a no-brainer if you're an expert. For a slightly more manageable size but still incredible quality, Monday the 7th of September morning with the offshore wind and solid swell is an absolute standout. The crowds at Turtles are often there, so expect company for these sessions.

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.
