The Lowdown
Alright folks, Rusty here. Let’s take a good hard look at what’s on the table.
Right off the bat, I gotta be straight with you – it’s a tough run ahead. For the better part of the next two weeks, we’re looking at a whole lot of nothing. Turtle Cove (a reef and point setup) is the only game in town, and for days on end, we’re stuck with tiny, weak dribble. There’s a solid gap from now until the middle of the third week where you’d be better off checking the tide charts than paddling out.
The first real flicker of life doesn’t show up until Wednesday, August 19th. That morning, we see a jump in size to about 6ft from the SSW, but it’s messy with a cross-shore wind. The afternoon though, that’s where you want to be. On the 19th, the wind goes glassy – dead calm – and the swell drops just slightly to a still-chunky 5ft from the SSW. The combined wave energy is strong at 291, meaning there’s some proper power in the water. The period is short at 8 seconds, so it’ll be a bit soft and crumbly, but that glass-off will make it clean. For a spot that’s been dead for weeks, that Wednesday afternoon is the standout. If you can only pick one session in this whole 16-day window, that’s it.
Other than that, you’ve got a few mornings with light winds, like Monday the 10th with an easterly glass-off, but the swell is barely a ripple at 2ft. Not really worth the wetsuit rub. Sunday the 16th has a dead calm morning but again, only 1ft. You’d be floating more than surfing.
Turtle Cove takes swell from the SE, and most of the decent pulses come from the SSW, so it’s not perfectly aligned. The water temp is about average for this time of year, nothing wild to report. Crowds are a “sometimes” thing here, but with this forecast, I doubt you’ll be fighting for a wave.
Bottom line: save your energy for the 19th (Wednesday). That afternoon is the only real chance for a proper surf. Everything else is a flat spell with a few glassy mornings for beginners to practice pop-ups.

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.
