The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' for Turtle Cove.
Well, I gotta be straight with you, it's a pretty grim stretch ahead. We're looking at a solid 16 days of forecast, but honestly, the first ten days are a write-off. There's just nothing worth paddling out for. The swell is tiny, the wind is either onshore or cross-off from the wrong angles, and the energy is weak. You'll be staring at flat, bumpy water. It’s a long, quiet spell.
There is a flicker of life on Wednesday the 9th of September. The morning brings a jump in energy, with a combined swell energy of 231 (moderate). The swell from the SSE hits 4.9 ft, but with a short, weak period of 7 seconds. The wind is a light cross-on from the SSE, creating small ripples, not ideal. The conditions are described as marginal, and it's a big step up from the nothing we've seen, but it's not the kind of day you'll be telling your mates about.
The real standout, the only window worth circling on your calendar, is the morning of Thursday the 10th of September. We get a clean offshore breeze from the SSW, which is perfect for this reef and point setup. The swell is a modest 2.0 ft from the SSE, but it's got a longer period of 9 seconds, giving it a bit more shape and energy (101 combined energy). The water temp is about average for the time of year at 70°, nothing unusual. The tide might be a factor, but if you can find it on the push, it'll be a clean, fun little session. Expect crowds, as it's a known spot that can get busy.
After that, it's back to the doldrums. The wind swings back onshore and the swell fades. Nothing else in the entire 16-day window comes close to that Thursday morning.
So, keep your board in the car and your eyes peeled. That Thursday the 10th is your best bet. It's not a bomb, but it's the only wave in town.

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.
