The Lowdown
G’day, Rusty here, your local surf reporter. Let’s take a look at the surf over the next couple of weeks around Turtle Cove.
Alright, I’ll be straight up with you: we’ve got a long, lean patch ahead. For the first week and a half, the swell is tiny and the conditions are just not cooperating. Real frustrating stuff, but that’s the way it is for now.
We start off Thursday, September 3rd with some weak 2ft to 2ft swell from the SE at 9 seconds, but the wind is blowing cross-off at 12 mph. It’s just poor surf conditions. Friday the 4th is flat and glassy in the morning with 1ft swell, but again, nothing to get excited about. Through the weekend and into the start of the following week, the swell stays below 3ft, with onshore and cross-onshore winds making it lumpy and choppy. There’s about a solid week of barely surfable waves.
The only day that even pokes its head up is Thursday, September 10th. We finally see a pulse of swell – 6ft coming from the SSW with an 8-second period. The combined energy jumps to 396 (moderate wave energy), which is a real stand out compared to the rest. The wind is still cross-off from the SW at 15 mph, so it’s clean. But even then, the forecast says it’s “marginal” – maybe a tide issue, maybe the quality isn’t there. For Turtle Cove, a reef and point break, that SSW direction isn’t the optimum (which is SE), so the waves might not set up as well as they could. Still, if you’re desperate for a paddle, Thursday morning and afternoon on the 10th is the only show in town for a couple of weeks. It’s a bit sizeable for beginners at 6ft, but fine for intermediates.
Beyond that, from Friday the 11th right through to Friday the 18th, it’s back to tiny 0.3ft to 4ft slop, with weak energy readings mostly under 100. The winds vary, but the surf quality is just poor – small, short-period windswell that’s not doing anything special. There’s a brief window on Wednesday the 16th with 4ft from the E at 5 seconds, but it’s cross-onshore and lumpy, so not worth the effort.
So, the honest truth? There’s only one potential highlight: Thursday, September 10th. It’s not a perfect day, but it’s the best we’ve got. Get in the water then, because the rest of the 16 days is a write-off for quality waves at Turtle Cove.
Rusty.

Information about the Turtle Cove Surf forecast
The above surf forecast table for Turtle Cove provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Turtle Cove can be found by selecting the local surf guide option on the grey menu. Our Turtle Cove 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 (Turtle Cove) 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 Turtle Cove 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.
