The Lowdown
Right, let’s have a look at what we’ve got on the cards. This is for Turtles, a reef break that handles a solid SSW swell and is strictly for the advanced crew.
Overall, we’ve got a long window of surf, but conditions are going to be real hit and miss. The standout session is definitely on Sunday, August 30th, first thing. That morning is glassy with a clean 6ft of WSW groundswell rolling in at a very long 17 seconds. That’s proper groundswell, packing a lot of punch with a combined energy of 2089, and the offshore wind will have it looking perfect. The water temp is sitting at 73°, a smidge warmer than average for this time of year, so it’s comfortable.
Other early mornings are worth a look if you’re keen. Tuesday, September 1st and Wednesday, September 2nd are both clean with that cross-off wind, offering up 6ft and 7ft of SW swell respectively. They’re a bit more of a gamble with that ‘marginal’ feel to them, but clean waves are clean waves. The combined energy on the Wednesday morning is a solid 1760.
Now, there’s a big gap of poor afternoons and messy days in between, but hold on for Monday, September 7th. That morning has a solid 7ft SW swell at 17 seconds and a fresh offshore wind (2927 combined energy) – it’s powerful and clean. The afternoon gets even better with a light offshore wind and a 7ft swell (2201 combined energy). That afternoon slot looks excellent for the experienced surfer.
After that, things get a bit lumpy again with shifting winds and cross-on slop. The waves get bigger towards the end of the second week, with Friday, September 11th and Saturday, September 12th pushing 8ft and 7ft, but the wind is never good. The big one to watch, though it’s a long way off, is Sunday, September 13th. That morning is pumping 10ft of WSW swell at a very long 18 seconds from a SSW direction. The combined energy is a massive 6626, which is serious power, but it’s coming in with a cross-on wind making it choppy. That’s proper big wave territory, experts only if you can deal with the mess, as it’ll be lumpy and raw.
There are a lot of days where the afternoon wind ruins it, so stick to the mornings. The consistent thing here is the swell, but the wind and chop will keep you working for it. Keep an eye on that Sunday, August 30th morning – that’s the pick of the bunch by a long way.

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.
