The Lowdown
Alright folks, Rusty here. Let's have a look at what the next couple of weeks have in store for us.
Right off the bat, I gotta be straight with ya – this is a tough stretch. We're looking at a long, quiet period ahead. The first real chance to wet a line doesn't show up until Thursday the 10th, but honestly, it’s a bit of a tease. For a good week after that, the surf is small and the conditions are just average. There's a flicker of something bigger right at the tail end of the forecast, around the 21st, but it comes with some serious wind issues. Let's break it down.
Thursday the 10th is probably the pick of a very average bunch. We've got a bit of muscle coming in at Turtle Cove – a reef and point setup that likes swell from the SE. The morning sees a clean 6 ft swell from the SSW, but it's got a short, weak period of 7 seconds. The combined energy is only moderate (296). Winds are a moderate WSW offshore, which will keep the surface glassy. With the swell just over 5 ft, it's a bit much for beginners, but for the intermediates, it's the best we've got. The water temp is about average for this time of year. After that, the swell backs right off. Friday the 11th through to Wednesday the 17th is mostly tiny, with heights barely scraping 2 ft and poor wind conditions. It’s a real nothingburger for almost a week.
We do get a pulse of energy returning around the 21st of September. The swell builds to a consistent 5 ft from the east on the 22nd and 23rd, with the energy climbing into the strong range (327 on the 23rd). The period stretches out to a moderate 10 seconds. Problem is, the wind is blowing straight onshore from the east and southeast, making for lumpy, poor conditions. For a point and reef, that onshore wind is a killer. That setup looks a lot more interesting for kite surfing than a traditional paddle session.
Honestly, you might need to wait for the next forecast cycle to get something truly clean and punchy. The real highlight, if you can call it that, is that Thursday the 10th morning session. After that, it's a waiting game.
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.
