The Lowdown
Alright, Rusty here, checkin' in on Turtle Cove.
Honestly, the next several days are a total dud. From Friday the 17th right through to Tuesday the 22nd, there’s nothing doin’. The swell is tiny, the period is short, and the energy is pathetic—like 12 to 13 for the first bit. Don't even bother waxing up.
Now, things take a wild turn on Wednesday the 22nd. A proper southerly swell shows up, hittin' about 7ft in the morning with a combined swell energy of 657. The wind is messy with some thunderstorms around, but come Wednesday afternoon, it cleans right up with a strong offshore wind from the west at 25 mph, pushing the swell to 8ft and the energy to 1021. That’s some heavy stuff. But listen, that’s 8ft+ surf—experts only. The period is a short 9 seconds, so it’ll be hard to get into despite the clean faces.
Your real standout is gonna be Thursday the 23rd. The swell eases to a still-burly 6ft in the morning with a 9-second period and an energy reading of 505. The wind is a clean offshore from the west at 16 mph, giving you those smooth, lined-up waves. A little more manageable than the day before, but still a big-wave day. The afternoon drops to 4ft and stays clean. After that, it fades back into small, sloppy junk for the rest of the run.
The water temperature is a bit colder than usual for July, sitting at 68°.
Bottom line: wait it out until Wednesday the 22nd for the big stuff, but grab Thursday the 23rd morning—that’s the one.

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.
