The Lowdown
Alright, let’s be honest – Turtle Cove is pretty flat for the whole 16 days. We’re looking at a long stretch with barely any swell, so don’t get your hopes up.
From Monday the 7th through Wednesday the 9th, it’s tiny. Waves are 0.7ft to 1ft, mostly from the east or SSE, with clean but weak energy. The combined energy is just a whisper – 41 down to 13. Not even worth getting the wax out.
Thursday the 10th is the first bit of size, but it’s rough. A 6ft SSW swell hits in the morning, dropping to 6ft in the afternoon, but the period is a short, choppy 7 seconds. Energy jumps to 376 (moderate), but the wind is howling at 19–22 mph from the SW, making it bumpy and ugly. This is kite-surfing weather, not a paddle session.
Friday the 11th is the only real chance you’ve got. Morning brings a 3ft SSW swell with a 7-second period, combined energy of just 76 (weak), and a light NNW breeze at 6 mph keeping it clean and cross-off. Water temp is about normal for this time of year at 70°. It’s surfable, but it’s nothing special. If you’re jonesing, that’s your window.
From Saturday the 12th onward, it’s back to tiny: 0.7ft to 1ft waves from the SE or S, with weak energy between 8 and 66. Winds are usually cross-off or light, so it’s clean but dead flat. Even a 4ft spike on Saturday the 19th comes with a horrible 5-second period and the wind cranking to 28 mph – again, more for the kite crowd.
No real standout here. The best bet is that Friday the 11th morning with a 3ft swell and light wind. Otherwise, it’s a barren run. Turtle Cove is usually fairly consistent, so this kind of dead spell is a bummer, but forecasts change. Hang tight.

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.
