The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks.
To be straight with you, this is a lean stretch for Turtle Cove. The overall pattern is small, inconsistent, and mostly ordinary. We’re looking at a long, drawn-out run of tiny waves and tricky winds, with only a couple of brief windows that might get your toes wiggling.
For the first few days, starting Tuesday the 25th up through the end of August, we’re stuck with tiny swell – nothing over 3 ft, and mostly in the 1.0 ft to 2 ft range. The wind is a mixed bag, but even when it’s offshore or clean, there’s just not enough energy in the water. The combined energy is weak, sitting between 22 and 125 (a low to moderate reading). The water temperature is 70°, which is dead average for this time of year, so no surprises there.
The first real standout – and I use that word carefully – comes on the morning of Tuesday, the 1st of September. We see a bump in swell to 4 ft from the SSW, with a short 7-second period. The wind is light offshore from the W, so it’ll be clean. The combined energy is moderate at 165. This is the best looking window in the whole outlook, but it’s still ordinary surf. It’s small, weak, and the short period means it’ll be a bit lumpy and fat. For a beginner, this is manageable, but for anyone looking for a proper wave, it’s going to feel like a lot of work for little reward.
Beyond that, things drop back into the doldrums. From the 2nd of September onwards, the swell is all under 3 ft, with periods mostly short and often onshore or cross-onshore winds. The morning of Thursday the 3rd of September has a brief moment of glassy conditions on a tiny 2 ft SE swell, with a decent 10-second period, but the combined energy is only 103 – weak. It’s a small, clean window, but you’ll be on a longboard fighting for scraps.
The second week is a write-off. Tiny surf, strong winds, and a lot of poor conditions. The combined energy drops into the teens and thirties – basically zero push. The standout on the 1st of September is your only real bet, and even then, it’s a long way from firing. If you’re desperate for a paddle, that’s your window. Otherwise, this stretch looks more like a good time to tune your boards or go for a swim.
Stay patient, folks. The ocean is having a quiet spell.
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.
