The Lowdown
Alright folks, Rusty here. Let’s have a look at the next couple of weeks at Turtle Cove.
Right off the bat, I gotta be straight with you – the next week and a half is looking pretty grim. There’s a big gap of nothing much happening. From now until around the 8th of September, we’re stuck with tiny, weak waves. Most days have swell under 3 ft, and the energy is barely registering, with values like 20 (weak) up to 105 (weak) for that first afternoon. The wind is mostly cross-off or cross-onshore, and the conditions are just poor. You’ll see a lot of “poor surf conditions” in the notes. Honestly, it’s not worth the paddle for the first week.
Things start to look a little more interesting around the 9th of September. That’s when we get our only real standout of the entire forecast. Wednesday the 9th, the morning session is looking like the pick of the bunch. We’ve got a clean 3 ft swell from the SSE, but the period is a very long 14 seconds. That’s proper groundswell energy, and the combined energy is a solid 347 (moderate). The wind is a light breeze from the NNW, making it clean cross-off. For a reef and point setup, that long period is a real treat – it’ll wrap in nicely and give you some proper shape. The afternoon bumps up to 5 ft with even more energy (778), but that’s a bit more size and the wind picks up a little, so it’s a bit more marginal. Still, the morning is the real window.
The 10th of September has some leftover energy from the SSE, but the wind swings onshore and messes it up. The 12th of September has a solid 6 ft from the SSW, but it’s short period (7 seconds) and cross-shore, so it’s not clean. The afternoon of the 12th sees a drop to 5 ft but with a clean offshore wind, so that’s a decent backup if you’re desperate.
So, the call is: don’t bother this week. Wait for the morning of the 9th. That’s your best bet for a proper session. The water temp is about average for the time of year, sitting at 70° with a near-zero anomaly, so it’s not a shocker.
Stay patient, and keep an eye on the forecasts.

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.
