The Lowdown
Alright, Rusty here. Let’s be straight with you – this outlook is a bit of a heartbreaker for Turtle Cove. The entire 16-day window is a washout for decent waves. We’ve got a really long, quiet stretch ahead with nothing to get excited about.
Looking at the whole picture, there are simply no good surf options. The first few days are almost flat, with tiny 0.7ft to 1.0ft swells and poor conditions. That runs from Tuesday the 15th all the way through to Saturday the 19th of September. It’s just small, messy, or cross-offshore junk. Not worth paddling out for.
We finally see a bit of size bump up on Sunday the 21st pushing 7ft from the ENE, but the wind is a fresh cross-shore, making it lumpy and ragged. That combined swell energy is ramping right up – we’re looking at a reading of 316 (moderate wave energy) – but without clean wind, it’s just a messy, powerful wash.
The energy stays high through the 22nd and 23rd, with 5ft to 6ft swells from the east and even a reading hitting 851 (very strong wave energy) on Thursday the 24th with 7ft surf. But every time, the wind is onshore or cross-onshore, blowing the surface out. The setup is more interesting for kite surfing than paddle surfing through that whole stretch.
By the very end, on Sunday the 27th, we get a little window: a clean, light offshore breeze from the NW with 2ft swell from the south. The combined energy is 136 (weak to moderate). The forecast notes it’s “surfable but very ordinary.” That’s the closest we get to anything worthwhile, and it’s still tiny.
Honestly, this is a blank run. The break is fairly consistent but the conditions just don’t line up. It tends not to stay this poor for long, but for this window, save your energy. Check back in later.

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.
