The Lowdown
Alright, Rusty here. Let's have a look at what's coming our way for the next couple of weeks.
We've got a pulse of solid, long-period groundswell pushing in from the WSW, and it's all aimed at one spot: Turtles, a heavy reef setup that's strictly for the experienced crew. The forecast kicks off on Sunday the 30th of August, so there's no gap and no waiting around.
The best of the best lands on Saturday the 5th of September and Tuesday the 8th of September. On Saturday morning the 5th, we’re looking at a proper big one: a 10ft swell from the SW with a light offshore breeze. That means clean faces, absolute perfection for those who can handle it. The wave energy is through the roof at 3402, this is serious ocean power. For Saturday afternoon the breeze swings cross-on and strengthens, so get out there first thing.
Tuesday the 8th of September morning is another standout. A 7ft SW groundswell, period of 16 seconds, combined energy of 2270, and we’ve got clean offshore winds. This is a long-period swell, so it’ll have plenty of push and shape, but the water temp is about average for the time of year – nothing unusual there.
Sunday morning the 30th is also very good with a 6ft swell and glassy, clean conditions. That’s a solid start. The wave energy is high at 2089. Just be aware, this spot is inconsistent and it’s a shallow reef, so it’s only for the good guys.
Sadly, after that first week of action, things go pretty quiet. The swell drops, the winds get messy, and it’s a lot of marginal to poor conditions. There’s a small window on Monday the 7th of September morning (7ft, clean cross-off wind, energy at 2604) but that still only scores a “marginal” call. The rest of the second week is a mixed bag of onshore chop and lumpy seas, with the odd clean morning but not enough swell to get excited about. The only real exception is Monday the 14th of September morning, but that 10ft swell has cross-shore wind, which on a reef like this, is more likely to be a washing machine than a classic.
Overall, if you’re an expert, get on it early in the first week. If you’re not, steer clear.
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.
