The Lowdown
Grab your coffee. Rusty here.
Looking at the next 16 days for Turtle Cove, it's a quiet stretch. We're looking at a lot of small, weak energy pulses that just don't have the size to make much of anything happen. The swell window isn't lining up, and there's a fair bit of wind to contend with. We've got a long gap of poor conditions before we finally see a pulse of energy on Thursday the 10th, but even that comes with a hefty side of wind.
Right now, the water temp is sitting at 70°, which is pretty much bang on average for this time of year.
The one standout window is around Thursday the 10th. The swell bumps up to 7ft from the SSW, with a combined energy of 454 (moderate). That’s the biggest pulse of the whole run, but it’s a short-period swell of 7 seconds and the wind is a cross-off from the WSW at 19 mph. For a reef and point like Turtle Cove, that kind of short-period swell can be a bit walled-up and not as well-shaped as you'd hope. It’s definitely not for beginners – over 5ft – but the cross-off wind will keep it reasonably clean. Honestly, with those winds, this setup might be more interesting for a kite session than a paddle session.
After that, it's pretty grim. We slide back into tiny, weak waves for days. There’s a brief moment on Monday the 14th where we get surfable but ordinary conditions with 3ft swell and light cross-off winds, but it's hardly a call to action. The rest of the run into the second week is all small, choppy, or onshore junk.
Honestly, if you're desperate for a wave, keep an eye on that Thursday the 10th. Otherwise, save your energy. The forecasts can change, but this one’s looking like a long, slow blank.
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.
