Table - best surf conditions forecast for Turtle Cove over the next 16 days.
The Lowdown
Alright, Rusty here. Let’s break down what’s coming up for Turtle Cove over the next couple weeks. Honestly, it’s a real struggle to find a clean wave. We’ve got a big dead stretch at the start, and the only half-decent window is pretty far out and blown out.
The Big Picture
The first half of this 16-day period is ugly. Thursday the 10th and Friday the 11th show some swell, but the quality is terrible. On Thursday morning, there’s a 6ft SW swell with a short 7-second period, coming with a fresh offshore wind. The combined energy is weak at 315, and the call is marginal at best. Water temp is about 70°, which is normal for the season.
From Saturday the 12th, we drop into flatness with readings of 1ft down to 0.3ft for days. There’s a long stretch of nothing through to Monday the 16th. On Sunday the 13th afternoon, you get a glassy 3ft wave, but the period is a miserable 5 seconds, so it’s barely a bump. That’s almost a full week of no surf.
The Only Possible Window
The only time I’d even consider checking the ocean is on Monday the 21st of September. There’s a jump to 4ft from the ESE with a short 6-second period. The combined energy hits a moderate 147, which is the most we see. But the wind is howling from the ENE at 19 mph, cross-onshore, making it lumpy and poor. For Turtle Cove, a reef and point break, the ideal swell direction is from the SE, so the ESE is a bit off. It’s a tough call, and with that strong onshore wind and the setup here, it honestly looks better for the kite surfers than for a clean paddle session.
Then Tuesday the 22nd brings absolute chaos – 47 mph winds from the ENE, a severe gale, with a 3ft wave and moderate energy at 235. Not a day for the lineup. The rest of the month follows with strong winds and lumpy conditions.
Final Call
No good surf in the first week-plus. The one potential window around the 21st is shredded by wind. It’s a bummer, but that’s the way it goes sometimes. For a spot that is fairly consistent, it doesn’t usually stay this flat for long, so keep an eye on the forecasts.
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.
