The Lowdown
Alright, this is Rusty. Let's have a look at what we've got coming down the line for Turtle Cove.
Overall, the next couple of weeks look pretty grim for getting a decent wave. There’s a lot of wind and messy conditions for most of it, with only a very small window where things come together. You’re going to have to be patient.
The water at Turtle Cove is sitting at about 68°, which feels a bit colder than normal for this time of year.
The first real chance to paddle out comes on Tuesday, August 4th. Tuesday morning is the standout, no question. We’ve got a 5ft swell rolling in from the south with a short 8-second period, and what makes it special is the wind—dead glassy, coming from the WNW at just 3 mph. That’s going to leave the surface like a mirror. The energy is moderate (247). It’s a reef and point set-up, and the swell is coming from the south, which is close to that optimum SE direction, so it should wrap in okay. It won't be huge, but if you’re after a clean, fun little wave, that’s your moment. Keep in mind, crowds are possible here sometimes.
After that, it falls apart. Tuesday afternoon the wind swings and the conditions get ordinary again. For the rest of the first week and into the second week, it’s mostly cross or cross-off winds with small, weak swells and a lot of wind. There’s a window on Saturday, August 8th morning with a 3ft south swell and light WSW wind, but it’s only surfable, not good.
Then we move into the second week. From August 10th onward, the swell picks up—we’re seeing 5ft to 7ft south swells on the Monday and Tuesday, with strong breezes up to 28 mph. That’s going to be a blown-out mess and only for experts if anyone’s keen on a beatdown. The energy gets strong on Monday afternoon (422), but with that wind, it’s not worth it for a paddle board.
From August 12th right through to the end of the forecast on the 17th, it’s all small, weak swell with poor conditions, onshore winds, and chop. There’s a massive gap with nothing worth chasing. You’d be better off doing something else.
So, if you’re hanging for a wave, keep your eyes on Tuesday, August 4th morning at Turtle Cove. That’s the one and only highlight across this whole stretch, and because it's a reef break, those long-period swells won't be an issue here. It’s a near-term call, but it’s looking like your best bet.
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.
