The Lowdown
Alright mate, Rusty here. Let’s have a look at what’s cookin’ for Turtle Cove over the next couple of weeks.
Honestly, I’ve gotta be straight with ya – this is a flat spell with very little to get excited about. The whole 16-day window is a struggle, and most days you’ll be staring at a lake. There’s a brief moment where the stars almost align, but it’s not the kind of swell that’ll have you calling in sick.
The only real window where you might even bother paddling out is on Thursday the 3rd of September. We’ve got a 3ft swell rolling in from the SE, with a short period of 6 seconds. That’s not exactly groundswell, it’s more of a windswell bump, but what makes it interesting is that early morning the wind is blowing offshore from the WSW at 12 mph. That’ll clean up the faces at this reef and point set-up. The combined energy is moderate, sitting at 102. It’s a “surfable waves but very ordinary conditions” kind of deal – a score of 1 out of 10 tells you it’s not gonna be a classic. But with offshore wind and a small swell, you might snag a few fun ones if you’re really keen. The water temp is about average for this time of year, so no wetsuit drama.
After that, the engine shuts right off. The next time you see anything over 3ft isn’t until the 13th of September, when a 3ft SSW swell shows up again, but that’s faced with a cross-onshore ENE wind at 16 mph, making it choppy and messy. A quick look at the 15th of September shows a 4ft SSW swell, but the wind is cross-off and strong, so it’s not gonna be clean enough to recommend.
The rest of the period is a graveyard of tiny swells (1ft to 2ft), strong onshore winds, and just really poor surf conditions. On the 6th of September, we’ve got 25 mph winds from the NNE – that’s more of a kite-surfing day than a paddle-surfing one. The combined energy is weak, mostly under 100 for the vast majority of days.
So, really, your best bet is the morning of the 3rd of September. It’s not a standout, it’s just the only thing on the menu. Keep your expectations low. If you’re desperate for a paddle, that’s your window.
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.
