The Lowdown
Alright folks, this is Rusty. Let’s have a look at what’s shaping up for Turtles over the next couple of weeks.
Right off the bat, we’ve got a fair bit of swell on the way, but the wind is going to be a real battle for most of the first week. The real standout, the one you’d want to circle on the calendar, is the morning of Wednesday the 9th of September. After a few days of messy, blown-out conditions, we finally get a clean 6ft swell from the WSW with a fresh offshore breeze from the East. The period is a solid 16 seconds, so that’s proper groundswell energy. The combined energy is reading 1883, which is solid. It’s advanced wave heights, so this is for the crew who know what they’re doing.
The water temp is about average for this time of year, so nothing unusual there in terms of needing a thicker suit.
Now, let’s walk through the period. The 4th of September (Friday) is a write-off. We’ve got a 6ft SW swell but the wind is a messy cross-shore, and the combined energy is around 1524-1542, which is moderate, but the conditions are just too lumpy. Not worth the paddle out. Saturday the 5th is a bit bigger, with 8ft on the morning push, but the wind is cross-onshore and the energy is strong (3178), but it’s choppy and poor. Sunday the 6th sees the swell jump to 12ft, but with a strong breeze from the S, it’s just a washing machine. That’s expert-only in the barrel, and even then, the wind is terrible.
Monday the 7th and Tuesday the 8th are a step in the right direction. The swell drops to 6ft-8ft, and the wind goes cross-offshore, keeping the waves clean. The energy is still strong (up to 3676), but it’s a lot more rideable. These are decent days for experienced surfers, but the real gem is that Wednesday the 9th morning.
After that, the surf holds in the 5ft to 7ft range through the second week, but the wind gets tricky again. Thursday the 10th morning is clean with a moderate offshore, but the afternoon turns to crap. The 11th of September (Friday) morning has a clean 5ft swell, but it’s a bit weak.
The real wildcard is the morning of Friday the 18th of September. We’ve got a glassy 6ft swell from the SW. The wind is an absolute dream – dead calm, glassy – and the combined energy is 1042, which is moderate. The water is clean, and the conditions are described as excellent for experienced surfers. That’s a long way out, so don’t book the trip just yet, but it’s a promising little window.
Overall, the first week is a bit of a slog with the wind, but there are a couple of windows of clean, powerful surf. The 9th of September morning is the pick of the lot. The second week looks more fickle, but that glassy morning on the 18th is a real tease.

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.
