The Lowdown
Alright, grab your board and listen up. It’s Rusty here, and I’ve gotta be straight with you – the next couple of weeks at Turtle Cove are looking pretty grim for us paddle surfers. We’ve got a long, quiet stretch ahead, but there might be a little flicker of hope way down the line.
Right now, from Saturday the 22nd all the way through to the end of the month, the ocean’s just not giving us anything to work with. The waves are tiny, mostly below 2 ft, and when there is a little bump, the wind is either cross-on or just messy. We’ve got a lot of clean conditions thanks to offshore winds, but without any real swell energy, it’s just a flat, glassy lake. The combined energy is barely registering, with values mostly below 100, so don’t even bother paddling out. It’s a solid ten-day blank run for anything rideable.
There’s a tiny tease on Wednesday the 26th morning – the wind goes glassy, dead calm, and the water is a nice 72°, about normal for this time of year. But the swell is a pathetic 2 ft from the SE with a period of 9 seconds. It’s surfable, but it’s just ordinary, gutless waves. Not worth getting wet for, honestly.
The first real glimmer of hope doesn’t show up until Wednesday the 2nd of September. That morning, we finally see some proper energy with a combined swell energy reading of 282 – that’s moderate, solid juice. The swell is 3 ft from the SE with a 9-second period, and we’ve got a clean, cross-off wind from the SSW. This is the standout of the whole forecast. It’s not huge, but it’ll be the cleanest, most powerful surf we’ve seen in weeks. The break is a reef and point setup, so that longer period should wrap in nicely.
After that, it gets a bit messy again. Thursday the 3rd brings a bigger 4 ft swell from the S, but it’s short-period junk at 6 seconds and the wind is onshore, making it choppy. That kind of energy (283 combined) is better suited for a kite session than a paddle board. It’s just a sloppy mess.
So, to sum it up: don’t bother for the next week and a half. Mark your calendar for Wednesday morning, September 2nd. That’s your best bet for a clean, fun session at Turtle Cove. It’s still a long way out, so keep an eye on it, but it’s the only real light in this tunnel.
Stay patient,
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.
