The Lowdown
G'day, Rusty here, and I gotta be straight with you – the outlook for Turtle Cove is pretty grim. We're looking at a long, long stretch of nothing much, with a few days that are just barely surfable. The water temp is sitting right on average for this time of year at 72°F, so nothing unusual there.
The whole 16-day window is a real struggle. From Friday the 14th right through to the morning of Monday the 18th, it's all poor surf conditions. Tiny, weak swells with messy winds. The first real chance of anything comes on Monday the 18th, but it's not exactly a call to drop everything.
Monday the 18th – Tuesday morning looks like the only real window. On Tuesday morning the 18th, we get a 4ft swell from the SE, with a period of 8 seconds, and a light cross-offshore NNW breeze. The combined energy is moderate at 163. It's described as "surfable waves but very ordinary conditions," so it's small and a bit weak, but at least it's clean. Tuesday afternoon is similar, with a 3ft swell from the SE and a light cross-off breeze from the south. Nothing to write home about, but you could get a few fun ones if you're desperate.
Wednesday the 19th morning is the best of a bad lot – a tiny 3ft SE swell, a 7-second period, but the wind is glassy from the WSW. The energy is weak at 74. It'll be clean, but the waves are going to be small and weak. After that, it's back to the doldrums.
From Thursday the 20th onwards, we're back to poor surf conditions. There's a bump in swell energy on Thursday afternoon with a 5ft SSW swell (206 energy), but it's a short period, messy wind, and the conditions are rated poor. The rest of the week into the end of the month is a mix of small, weak, onshore slop and clean but tiny leftovers. The period from Saturday the 22nd to the 29th of August is just a long, blank run of poor surf.
So, the honest truth is, there's no standout here. The only two days worth even looking at are Tuesday the 18th and Wednesday the 19th, and even then, it's just for a quick paddle on a small board. If you're a beginner, the swell never gets above 5ft into the 'too big' zone, but it's too weak and small to really learn on. For everyone else, it's a case of wait and see if the forecasts change for the better. This area can be fickle, but it tends not to stay this poor for long.
Stay patient, 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.
