The Lowdown
G’day, Rusty here. So we’re lookin’ at Turtle Cove for the next couple weeks, and mate, it’s pretty bleak. There’s not much to get excited about—mostly tiny swell and messy wind, with hardly any sessions worth paddlin’ out for.
We kick off Thursday, August 27th, with a little 2ft SE swell on clean cross-off wind at 12 mph, but the combined energy’s only 75—real weak. That pattern holds through the weekend and into next week. Saturday the 29th afternoon shows a tiny blip with light wind and clean 2ft surf, but it’s still shin-biters. By Sunday the 30th, we’re down to 1ft and the wind’s up. Water temp’s 70°, which is about average for the season.
Then comes a proper dry spell from Monday, August 31st, all the way through Monday, September 7th—more than a week of barely a ripple. Swells hang around 1ft to 2ft, and the wind’s either howlin’ onshore or just plain wrong. The only tiny bright spot is the morning of the 7th: the wind goes glassy and there’s a 1ft E swell, but with combined energy of only 27, it’s a puddle.
Come Tuesday, September 8th, we finally get a pulse—6ft of SSW swell with clean cross-off wind at 12 mph. Combined energy’s 227 (moderate), though the period’s short at 6 seconds—it’s the best we’ve seen but still pretty marginal. That fades into Wednesday the 9th.
The real standout, if you can call it that, lands on Friday, September 11th. We got 6ft of SSW swell with a 7-second period, cross-off wind at 12 mph, and combined energy of 345 (moderate). For a reef and point like Turtle Cove, that energy with clean offshore breeze should produce some rideable, if a bit short-period, waves. But it’s still a marginal call.
So, first week’s a bust, second week has one or two half-decent moments. If you’re keen, the 11th is your best bet, but don’t get your hopes too high.

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.
