The Lowdown
G’day, I’m Rusty, and I’ve got the local lowdown on what’s coming our way.
Honestly, mate, it’s a pretty flat and frustrating stretch ahead. The next 16 days are looking grim for any decent surf at Turtle Cove (reef and point). We’ve got a run of tiny, weak swells and a whole lot of poor conditions, so don’t get your hopes up too early.
The water’s sitting at a warm 71°, which is pretty much what you’d expect for this time of year – nothing unusual there.
The first real hint of anything surfable comes on Sunday afternoon, 23rd August. It’s still not great – just 3ft of swell from the south with a short 5-second period, so it’s pretty weak and jumbled. The combined energy is only 59, so barely any push. But the wind goes glassy in the morning, then cross-off from the SSW in the arvo, so it’ll be clean. Still, it’s only “ordinary” at best.
Monday 24th August has a similar story – 3ft south swell, 6-second period, 83 energy, but the wind turns offshore from the west in the afternoon, offering clean conditions. Again, nothing to write home about.
Tuesday 25th August sees the swell drop to 1ft, but the period stretches to 11 seconds – a bit more groundswell character. The energy’s only 49, so it’s weak. Clean conditions though, with cross-off winds.
Things get a bit more active from 28th August onwards, but it’s messy. On Friday 28th August, the swell jumps to 3ft from the ESE with a 6-second period, and the combined energy hits 110 (moderate), but the wind is a fresh 19 mph cross-onshore, making it lumpy and poor. Not worth paddling out.
The weekend of 29th–30th August sees the swell build to 4ft from the ENE on Saturday morning, with energy climbing to 184, but it’s onshore and messy – 19–25 mph winds. This is more kite-surfing territory than clean surf.
There’s a glimmer on Tuesday 1st September morning: 1ft from the SE with a 12-second period, but cross-on light winds. That afternoon, though, it goes glassy with 2ft of SE swell, 12-second period, and energy of 161 – moderate. It’s still only “ordinary” quality, but that’s the best we’ve seen in a while.
Wednesday 2nd September afternoon also offers clean cross-off winds and 2ft SE swell, but energy drops to 99.
Overall, nothing stands out as a true winner. The best bet is the glassy afternoon of 1st September, but it’s small and mediocre. If you’re desperate for a paddle, that’s your window.

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.
