The Lowdown
Alright folks, Rusty here, looking at the upcoming swell for Turtles.
First up, the water temp is sitting at 72°, which is pretty much what you'd expect for this time of year, nothing weird going on there.
We’ve got a solid run of surf on the cards, but it’s not all going to be clean. The standout session without a doubt is Tuesday the 8th of September morning. We’ve got a powerful 7ft swell rolling in from the WSW with a long 18-second period – that's proper groundswell energy, you'll feel the push. The combined energy is pumping at 4177, and with a clean cross-off wind from the NE, Turtles is going to be firing. Just a heads up, at this size and with that long period, it’s going to be a beast for experts only, and the conditions will be best for a reef setup like this one.
Before that, Monday the 31st kicks things off with a 7ft WSW swell, but the morning is your only window with light southerly winds. By the afternoon the cross-on breeze kills it, so get in early. Monday the 7th of September morning is also worth a mention – another 7ft SW swell and clean cross-off winds, giving you 3040 in energy. That’s a good, solid session.
Looking further ahead, Tuesday the 15th of September morning looks like another absolute highlight. The swell holds at a solid 7ft from the WSW with a 16-second period, but the real treat is an offshore wind from the east. That’s a rare combination for Turtles and it means perfection. The energy is strong at 2441. Again, this is expert territory at that size.
Be aware, Turtles is often crowded and it's a fairly consistent spot, so expect company on the good days. The afternoons through this whole period are generally a write-off with strong cross or onshore winds, so stick to your dawn sessions.
Later in the run, like Saturday the 12th and Sunday the 13th, the swell drops back and the winds stay messy. There’s a glimmer on Friday the 11th morning with a clean 6ft swell and gentle winds – that one is rated as excellent for experienced surfers. The long-range stuff like the 14th and 15th is looking promising, but it's still a way off, so keep an eye on it.
Signing off,
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.
