The Lowdown
Alright, Rusty here. Let's be real about Turtle Cove. It's a bleak outlook for the next couple of weeks. The first solid week and a half is basically a flat spell, so don't get your hopes up.
The first time you might even bother looking at the water is Monday, September 14th. Even then, it's ankle-snappers at 1ft from the southeast, with a 9-second period. The morning wind is a light cross-off, making it clean, but the energy is pathetic (57). It's just barely surfable. The water temp is about average for the season, nothing to write home about.
The real issue is that for days on end, the wind is a problem, and the swell is either tiny or, when it does show up like on Thursday the 10th, it's a messy 6ft from the southwest with a short, crummy 7-second period. That's a lot of windswell energy (408) but absolutely no shape. For a reef and point break, that's a total washout. Honestly, it looks more like a kite-surfing day than a surfing one.
From the 14th onward, it's a long, flat slog. There's a little hope on the 18th with a 1ft wave from the southeast and a 12-second period, and the wind is offshore from the west. That's a good setup for a point, but the wave is just too small. The 20th and 21st have some clean offshore mornings, but again, we're talking about 1ft leftovers. The crowd factor is listed as "sometimes," but with this little swell, you'll be the only one out.
There's no standout day here. The entire 16 days are a bust. The best you can do is a tiny, clean wave on the 14th or 18th, but it's not going to be anything to write home about. Keep the board in the car, but don't rush.
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.
