The Lowdown
Alright mate, Rusty here with the imperial rundown.
First thing: the water is sitting at 73°F, which is about 1°F warmer than the long-term average for this time of year. Nothing too wild, just a touch on the mild side of normal.
The standout for the whole run is Turtles (reef break). This spot is exposed to the swell and it really loves a good SSW direction. The best session you’ll see is on Sunday morning, August 30th. We’ve got a solid 6ft of swell rolling in from the WSW, with a very long period of 17 seconds – that’s proper groundswell energy. The wind is glassy, dead calm from the NNW at 3 mph, so the surface will be like a mirror. Conditions are excellent for experienced surfers, but that long-period swell will be lining up beautifully on this reef. Combined wave energy is strong at 1978. It’s a fairly consistent spot, but it can get crowded often, so get in early.
The rest of the week leading up to that is a mixed bag of cross-shore winds and lumpy conditions. Thursday morning, August 27th, has a big 8ft WSW swell with a 16-second period, but it’s a cross-shore 19 mph S wind, so it’s lumpy and marginal. The swell energy is very strong at 3419, but it’s not clean surf. Friday and Saturday are similar – okay swell but the wind messes it up.
After that Sunday glass-off, the outlook gets a bit messy again. Monday, August 31st, has a clean 7ft swell, but the wind is cross-on from the SW, which puts ripples on the face. Tuesday morning, September 1st, is worth a mention: 6ft WSW swell, 16-second period, with a clean cross-off SSE breeze at 9 mph. That’s a decent option for a quick session.
From Wednesday, September 2nd, through to the end of the first week, we see the swell drop a little, with wave heights around 4ft to 6ft, but the wind is still mostly cross or cross-shore, so it’s not perfect. The second week (starting around September 5th) brings a big pulse of 8ft to 10ft SW swell, but the wind turns onshore and strong – 28 mph on the afternoon of September 5th. That’s going to be a messy, powerful mess. At that size, with strong onshore wind, this beach-and-reef setup might be more interesting for kite surfing than paddle surfing.
Later in the second week, around September 8th and 9th, we get another clean morning window: 5ft to 8ft WSW swell with a 17-second period and a light cross-off SE breeze. That’s promising but less certain this far out. The combined energy is moderate to strong. The swell is still coming from the SSW/SW, which is good for Turtles.
Overall, the best bet is that Sunday morning glass-off at Turtles. Everything else is a fight with the wind. If you’re keen, go for it. If not, wait for the forecast to change.
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.
