The Lowdown
G'day, I'm Rusty, and I'm staring at the charts for Turtle Cove. Honestly, it's a tough stretch ahead. The 16-day window kicks off with a real flat spell, and we're looking at a solid 5-day gap from the start with no worthwhile surf on offer. The water temp is sitting at 70°, which is about average for the time of year, nothing to write home about.
The first glimmer of hope comes on Thursday, the 3rd of September. The morning session is where it's at. We've got a clean 7ft swell pushing in from the SSE with a moderate offshore wind from the west. The wave energy is moderate (363), and those offshore conditions will keep the lineup tidy. The swell is a bit stout at 7ft, but that's a decent size for intermediate surfers – it's not a beginners' wave. The period is a short 7 seconds, so it's a bit lumpy and wind-driven, but it's the best we'll see for a while. The afternoon hangs in there with a 5ft swell from the SE and a gentle offshore wind, still clean and rideable.
After that, it's back to the doldrums with a long gap of weak, onshore, and messy conditions until we get a standout on Wednesday, the 9th of September. Again, the morning is the pick. The models are hinting at a 3ft swell from the SSE, but with a long 12-second period, which means proper groundswell energy. The combined energy is strong at 501, and we've got a moderate offshore wind from the west. This is a beautiful, clean setup for a point and reef break like Turtle Cove. The long period will draw out the lines, making for some well-shaped waves. The smaller size (3ft) keeps it accessible for intermediates, and the offshore breeze will keep the faces glassy. The afternoon is a bit weaker with a shorter period, but still clean.
Beyond that, the second week looks pretty grim with mostly small, onshore, and choppy conditions. Nothing else worth paddling out for. If you're looking for a session, lock in the 3rd of September morning or the 9th of September morning. The 9th is the real standout with that long-period groundswell and clean offshore winds. Keep an eye on the forecast, though, as it's a week out and could change.
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.
