The Lowdown
Alright, Rusty here, and I’m looking at Turtle Cove.
To be straight with you, the whole 16-day window is pretty lackluster. There’s very little to get excited about. The water is sitting at 68°, which is a bit cooler than normal for this time of year, so you’ll want a wetsuit.
We kick off on Saturday, August 1st, with a small pulse. The morning has 3ft of S swell, short period, with a cross-off breeze. The energy is weak, and it’s nothing special. The afternoon gets worse with stronger wind.
Sunday the 2nd is a total washout – tiny, messy, and poor. Monday the 3rd sees a big jump in size, with 6ft in the morning and a solid 8ft in the afternoon, but the wind is howling at 28 mph in the morning and 22 mph in the afternoon. That’s full-on kite-surfing conditions, not paddle surfing. There’s a ton of power in the water, but it’s blown to pieces.
The rest of the first week and into the second is a long, flat, and poor stretch. Swell is mostly 2ft to 4ft, with short periods, and the wind is never ideal. The only real standout is Thursday, August 13th in the morning. The wind goes dead calm, glassy, with 2ft of S swell. It’s tiny, but it will be glassy perfection for a longboard. The energy is very weak, but the conditions make it the cleanest wave of the whole forecast.
After that, it’s back to small, poor, and cross-shore junk through to Sunday the 16th. There’s a long gap of nothing.
So, the best you’ve got is that Thursday the 13th morning for a glassy, small-wave session. The Monday the 10th morning is a distant second. The rest of the 16 days? Don’t bother.
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.
