The Lowdown
Righto, let’s be straight with you. Looking over the next 16 days for Turtle Cove, it’s a pretty grim run. There’s not a single standout session on the table, and honestly, there’s no surf worth paddling out for. The whole period is a write-off for anything decent.
Starting from Friday the 11th, the swell is tiny and weak, with a small S’ly swell of 2ft at a short 6 seconds, and the combined energy is a measly 41. The wind is offshore from the WSW, so it’s clean, but the waves are just too gutless. Saturday the 12th is even smaller at 1ft, with onshore E wind making it a total mess.
Sunday the 13th brings a bit more size with a 3ft SSE swell, but the period drops to a pathetic 5 seconds. It's clean with cross-off winds, but that’s junk – no push, no shape. The next few days through to the 17th are all small, weak, and plagued by cross-shore or onshore winds. The swell never gets above 4ft, and most of the time the combined energy sits below 100, meaning the ocean is flat and lifeless.
There’s a tiny glimmer late on Sunday the 20th, where the wind goes glassy and the water turns to glass. The swell is 3ft from the ESE at 7 seconds, and the combined energy is 65 – still weak. The score is barely surfable, ordinary conditions at best. It’s the closest thing to a wave you’ll get, but it’s not worth the drive.
After that, things get properly ugly from Monday the 21st. The wind cranks up from the ENE at 25-31 mph, turning the ocean into a washing machine. The swell rises to 4ft on the 21st, with combined energy hitting 101 – just into moderate, but it’s cross-onshore and blown to bits. By Tuesday the 22nd and Wednesday the 23rd, the wind is near gale force, and although the swell energy jumps to 217 on the 23rd, it’s a complete mess – only for kites, not paddle surfing. The wind and chop make it unsurfable.
The last few days from the 24th to the 26th drop back to tiny, weak swell with dying cross-onshore winds. Nothing changes.
So, honestly Turtle Cove is a dead zone for the next two weeks. The best you can hope for is that glassy moment on the 20th, but even then, the swell is pathetic. Keep the board in the car and check back another time.

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.
