The Lowdown
G’day, Rusty here. Let’s talk about Turtles. This is an advanced reef break that faces the south-southwest, so it needs the right angle to get good. It breaks fairly consistently, but you’ll often find a crowd, so be ready to share.
Water temp is about 72°, pretty much average for this time of year—nothing unusual.
We’ve got a dry spell upfront. The first few days have some swell but the wind is messy, blowing cross or cross-off with a fresh breeze, and the surf quality is just marginal. Nothing worth paddling out for.
Thursday the 3rd through Saturday the 5th have increasing size, from around 6 ft to 8 ft out of the southwest, but the wind stays cross or cross-on, and most of it is lumpy or choppy. Saturday morning pushes 8 ft with a 16-second period, cross-off with a moderate breeze, and the energy is strong (3178). Could be okay for experienced surfers, but still just marginal.
The standout is Monday the 7th of September. Morning sees a solid 8 ft swell from the west-southwest with a very long 17-second period, and the wind is offshore from the east-southeast—fresh and clean. The combined energy is pumping at 4223. This is a proper groundswell for Turtles, and with offshore wind, it’ll be clean and powerful. The long period means long gaps between sets, so paddling out is easier, but at a reef, those sets will be fast and hollow. Monday afternoon holds up too, with 8 ft from the southwest and a cross-off breeze. That’s your best window.
Tuesday the 8th is also strong: morning offshore from the east with 8 ft at 16 seconds and energy at 3196. Clean and powerful, just a touch less size.
From Wednesday the 9th, the swell drops to 6 ft to 7 ft, and the wind turns onshore or cross-on a lot. Conditions get choppy, and the surf quality slides to marginal or poor. There’s a gap from around the 11th to the 13th with weak energy and messy winds.
One last look: the morning of Tuesday the 15th. That’s got 7 ft from the southwest, a 14-second period, and glassy offshore wind from the east at only 3 mph. Clean conditions with moderate energy (2055)—could be a sneaky good session.
The best on offer is Monday the 7th. Big, clean, powerful swell with offshore wind. For the advanced crew, that’s the day. Tuesday the 8th is a close second.
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.
