The Lowdown
G'day, I'm Rusty. Let's talk about Turtles, a solid reef break that's exposed to the swell. Right now, the water temperature is about 72°, which is pretty normal for this time of year.
The first week kicks off with a bit of a slow start, but there's a real standout brewing. From Tuesday morning, September 1st, we've got a 6ft groundswell from the WSW with a very long 16-second period. The combined energy is moderate at 1700, and with a clean cross-off wind, it's looking promising. The wind gets a bit of a chop on it in the afternoons, so mornings are the go. Wednesday and Thursday are messy with fresh cross-shore winds, so not great.
Friday morning, September 4th, is another clean session with a 6ft swell from the SW, 14-second period, and cross-off winds. The energy is moderate at 1537. Saturday sees the swell bumping up to 8ft, which is getting into expert territory, but the wind is messy. The real standout is Monday morning, September 7th, with a 7ft WSW groundswell, a very long 17-second period, and light offshore winds from the ESE. The energy is strong at 3416, and the waves will be clean and well-shaped. This is the pick of the first week.
Tuesday, September 8th, is another highlight for experienced surfers. The morning has an 8ft SW swell with a 17-second period, offshore winds from the ENE, and very strong energy at 3442. It's a big, powerful groundswell that will be best at this reef.
The second week gets a bit patchy. The wind picks up and the quality drops. Wednesday, September 9th, has clean morning conditions with a 6ft swell, but the afternoon turns onshore. Thursday, September 10th, has a 7ft swell with a 16-second period, but the wind is cross-onshore. Friday, September 11th, morning looks clean again with a 6ft WSW swell, but the afternoons are blown out. From the 12th to the 16th, it's mostly cross-shore and onshore winds with swell dropping off, though there's a bump on Tuesday, September 15th, with a 10ft SW swell that's too big and messy for good surfing.
Overall, the best windows are the mornings of September 1st, 4th, 7th, and 8th. The Monday and Tuesday standout with the clean, powerful groundswell.
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.
