The Lowdown
Alright, this is Rusty. Let’s have a look at the next couple of weeks.
We’ve got one spot on the radar, Turtles. It’s an advanced reef break that really likes a SSW direction. The problem is, for the first few days, the wind is just all over the shop. We’ve got a big, powerful, long-period groundswell rolling in over the weekend of the 5th and 6th – we’re talking around 8ft to 11ft of SW swell, with wave energy numbers in the thousands (3178 up to 4029). That’s a lot of water moving, but the wind is going to be a nightmare. On Saturday morning it’s a cross-on mess at 9 mph, and then it gets worse. Expect ugly, lumpy, cross-shore conditions through Sunday. This is not paddle-surfable for anyone but maybe a kite.
The water temp is sitting at a nice 72°, which is about average for this time of year, nothing weird there.
Finally, by Monday the 7th, we get a little window. The swell drops to a still-chunky 10ft with a 17-second period (very long period, meaning it’s a proper groundswell) from the SW. The wind switches to a clean cross-off at 19 mph. This is the kind of energy that will line up beautifully at a reef like Turtles, though the long period might make it a bit too straight for the beach. The wave energy is massive at 5248 – that’s strong.
Tuesday the 8th should be similar but a little smaller, with clean conditions in the morning.
But the real standout? Look at Thursday the 10th. The swell settles to 6ft, still from the WSW with a nice 15-second period. It's a moderate 1342 combined energy. The wind goes light and cross-off at 6 mph. Conditions will be clean. It’s still an advanced wave, but manageable for a strong intermediate on a good day. This is your best bet for a decent session.
Then there’s a gap. Friday the 11th is no good with a small, weak, onshore bump. The next real gem comes early on Saturday the 12th of September. That morning we get a 7ft groundswell with a 17-second period from the WSW, the wind is glassy (3 mph from the north), and the wave energy is a solid 2675. If you can get out before the afternoon cross-on kicks in, that’s another gold-plated session for experienced surfers.
Beyond that, the pattern keeps throwing size and wind issues at us. Around Tuesday the 15th we see another big pulse of 8ft at 16 seconds, with clean cross-off wind in the morning. That one looks very promising for the Monday morning of the 14th as well, with a 7ft SW swell.
The very end of the forecast, on Thursday the 17th, offers a small, glassy 5ft morning with a 13-second period. It’s a little weak (806 energy), but glassy is glassy, and it could be a nice quiet paddle.
The overall picture: there are some cracking clean windows for the advanced crew, but you have to pick your days. The wind ruins more than it helps, and when the swell is over 8ft, it’s expert territory. The 10th, 12th, and 15th mornings are the standouts. Don’t be a hero on a windy day at this reef. Wait for the glass.
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.
