The Lowdown
G’day, I’m Rusty, and I’ve been watchin’ this stretch of coast for a long time. Let’s talk about what’s comin’ up for Turtle Cove.
Right off the bat, I gotta be straight with you – this is a pretty lean run. The next sixteen days are gonna test your patience. There’s a big gap from now until the end of the first week where the surf is just too small or too messy to really get excited about. The first real chance to paddle out comes on the morning of Sunday, August 9th, but even then, it’s not a ripper.
Let’s break it down. The water temp at Turtle Cove is sitting at 70°, which is about 1° cooler than average for this time of year – nothin’ to write home about, just your standard early-August chill.
The strongest, most consistent window we’ve got lands on the morning of Sunday, August 9th. We’re lookin’ at a 4ft swell from the SSW, with a period of 6 seconds. That’s a short, choppy windswell, but with a light W wind blowin’ 6 mph straight offshore, it’ll be clean. The combined energy is moderate, sittin’ at 111, so there’s a bit of push there. It’s not gonna be a world-beater, but for a Sunday morning session, you could do worse. The sets will be a bit close together with that short period, so you’ll be workin’ hard, but the offshore breeze will make it feel like a proper wave.
The other little window that’s worth a mention is Saturday morning, August 15th. We’ve got 3ft from the S, 6-second period, and the wind is dead calm – glassy, mate. That’s a rare treat. The energy is weak at 87, so it’s gonna be a bit fat and slow, but if you’ve got a log or a mid-length, you’ll be trimmin’ on clean little peelers with no one else around. The crowds are listed as “sometimes,” so you might have a few mates out, but it’s not gonna be a circus.
The rest of the fortnight is a write-off, honestly. Mornings like Wednesday, August 12th, with a 2ft south swell and a light WNW offshore, look clean, but the energy is barely there at 47. You’ll be bobbing around more than ridin’. Tuesday, August 18th, has a similar feel with a 2ft SSE swell and a 9 mph WNW offshore, energy at 76 – still too small to get your heart racin’.
One thing to note: there’s a couple of days where the wind cranks up, like Sunday afternoon, August 16th, with a 22 mph SW blow and 4ft east swell. That’s a messy, choppy combo – more for the kite crew than us paddle surfers.
So, to sum it up: the standout is Sunday morning, August 9th, for the best combo of size and cleanliness. If you can wait, Saturday morning, August 15th, offers a glassy, small-wave session. For the rest, keep your board in the car and your eye on the forecast – it’s a dry spell, but it won’t last forever.
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.
