The Lowdown
Alright folks, Rusty here. Gotta be honest with you, the next two weeks around Turtle Cove are looking like a whole lot of nothing. I've stared at the charts 'til my eyes went crossed, and this is a test of patience.
We're starting with a real dead spell. From Wednesday the 19th through Saturday the 22nd, there's just no surf to speak of. Tiny, weak swell, and the wind is messing things up. Cross-off breezes that don't help, then onshore junk and even some rain on Saturday. This isn't surfing, this is just staring at flat water. It's a real drag.
We get a tiny glimmer of hope on Sunday the 23rd in the afternoon. The swell bumps up to a pathetic 2ft from the south with a short 5-second period. The wind goes light cross-off, so it cleans up, but the energy is just pitiful – we're talking a combined energy of only 52. It's technically surfable, but you'd be scratching for anything. It's one of those days you paddle out more out of habit than expectation.
But then, the wind actually goes fully offshore for the first time on Monday the 24th. The morning is still weak, but the afternoon is your window. We get a pulse to 5ft from the SSW, and that's enough to bump the energy up to a moderate 208. The wind is a moderate offshore and the surf is clean. This is the one real highlight in this whole forecast. It won't be epic, but it's a proper surf. That late Monday session is your best bet, hands down.
Now, hold onto your boards. From Tuesday the 25th all the way through to the end of the month, we're back in the doldrums. The swell drops right back down, the winds turn onshore or cross-onshore, and things get lumpy and messy. The 27th and 28th see a bit more size, with the swell pushing to 4ft, and the energy gets strong, hitting 401 on the 28th morning. But it's all for nothing, because the wind is howling from the NE at 19-22 mph, making it a complete, choppy mess. That's not surf, that's a washing machine. If you've got a kite, that might look more fun than a paddleboard.
We slide into September with a weak whimper. A few clean days on the 1st and 2nd, but the swell is down to 1ft. Long period, sure, up to 14 seconds, but with no size, it's just a ripple. On the 3rd, the energy picks up a bit to 144, but it's onshore and still tiny. All in all, a pretty bleak outlook. There's one standout session, and that's Monday afternoon. Don't miss it, because otherwise, it's a whole lot of nothing for a while.
Alright, stay patient, keep an eye on that Monday arvo forecast, and I'll see you out there.

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.
