The Lowdown
Alright folks, Rusty here. Let’s look at what Turtle Cove has in store for the next couple of weeks.
Bottom line: it’s going to be a long, dry wait. The first real chance to paddle out doesn’t come until Wednesday, September 9th, more than a week away. Everything before that is blown-out or flat, with onshore winds and junky conditions.
On that Wednesday the 9th, we finally get a little window. The wind goes glassy – dead flat – which is a beautiful sight. We’ll see a 4ft swell rolling in from the SSW, with moderate energy (203-234). That’s the one true standout in the whole outlook. It’s not a huge wave, but the clean, glassy surface will make it feel good and inviting. The direction is a bit off for the cove’s ideal SE swell, but when the wind is that good, you take what you can get.
After that, it’s right back to the same story: onshore winds and tiny, weak surf. Not much for a surfer to hang a hat on. Turtle Cove is a reef and point setup that’s fairly consistent, so a run this quiet stings a bit.
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.
