The Lowdown
Alright, I’ll switch it over for the imperial folks now. Rusty here again.
Let me break it down for Turtle Cove over the next 16 days. Honestly, it’s mostly a dry spell. There’s a long stretch of nearly two weeks where the surf is just not happening. The only real chance you get is on Tuesday, August 18th.
From August 9th all the way through the 17th, it’s real quiet. Tiny waves, messy wind, and hardly any push. The combined energy reading is weak, mostly in the tens and twenties (57, 28, 53, 24), so nothin’ doing. Water temp is right at 72°F, which is about average for this time. No excuses.
Then comes Tuesday morning, August 18th. That’s the one highlight. Turtle Cove gets a 5 ft swell out of the NE, with a short period of 6 seconds. The swell energy hits a decent 307, and the wind is glass – dead calm, just a slight air. That’s gonna be clean as a whistle for the reef and point. For intermediate surfers, this is your window. The offshore wind direction is W, which suits the spot. Crowds are only “sometimes” around, so you’ve got a fair shot at a good session.
The afternoon of the 18th fades quick – swell drops to 5 ft, wind turns cross-off, and it’s just marginal. After that, you’re back to slim pickings. There’s a pulse on the 20th with a 6 ft SSW swell and energy at 296, but the wind is cross or onshore, making a mess of things. Not worth the hassle.
From the 21st onward, it’s flat and funky. Even a glassy morning on the 23rd only gives you 1 ft of swell – you’re just floatin’.
So here’s the plan: if you want a wave, aim for the morning of Tuesday, August 18th at Turtle Cove. Everything else is a long, empty gap. Hang tight.

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.
