The Lowdown
Alright, Rusty here again. Let's talk about Turtle Cove for the next couple of weeks.
The long and short of it is, we’re in for a pretty rough stretch. There’s a big gap right from the start, and we’re not lookin' at any real surf for several days. From now until Monday the 4th of August, it’s a wasteland—small, weak, and blown out. Nothing worth paddling out for.
The Only Real Window: Monday Night / Tuesday Morning (4th - 5th of August)
Our one and only chance is on Tuesday morning, the 5th of August. We get a pulse of swell from the south-southwest, about 8 feet (2.4m) with a 13-second period. That's got some juice (combined energy of 381). That size is getting serious; it’s not a beginner wave, more for the experienced crew.
The wind will be a light northwesterly, making it glassy and clean for the reef and point at Turtle Cove. It’s a pretty consistent spot, so it'll be breaking. But the direction isn't ideal for this place. That short-period swell will wrap in, but it might not have the best shape.
After that morning, the window slams shut. The wind swings onshore, and the swell drops dead all over again. There’s a little pop of bigger surf around the 10th, but the wind will be blowin' hard and ruining it.
Water Temp & Final Word
The water’s running about a degree and a half colder than usual at 68°F. Not a huge deal, but you’ll feel it if you’re used to warmer water.
So, honestly, if you miss that Tuesday morning window, you’re out of luck for the whole 16 days. It’s a pretty quiet spell for Turtle Cove.

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.
