The Lowdown

Alright, Rusty here, let’s talk about what’s cooking at Turtle Cove. We’re looking at a pretty flat spell ahead, so don’t be in a rush to grab your board just yet.

Right now, the water is sitting at about 69°, which is pretty much what you’d expect for this time of year – no surprises there.

The first few days are a bit of a write-off. Wednesday morning offers up a tiny 0.7ft SSE swell, but with a cross breeze and weak energy (13), it’s just not doing anything. Thursday morning sees a jump in size to 6ft from the SW, but that’s a short-period 7-second wind swell with a big 19 mph cross-off wind. The combined energy is moderate (318), but the wind is too strong for it to be any good – it’s a messy, blown-out situation. That kicks off a long, dry stretch. From Wednesday the 9th right through to Tuesday the 17th, there’s nothing worth paddling out for. The swell stays tiny, under 3ft, and the wind is either wrong or too strong.

Now, there’s a little glimmer of hope on Friday the 18th. The morning session shows a 6ft SW swell with glassy conditions and a very light breeze. That’s a clean look, and the combined energy jumps to 446, which is solid. The period is only 7 seconds though, so it’s a short-period wind swell, not a long grinder. Still, with glassy conditions, that’s your best bet in the whole 16-day window. It’s an intermediate reef and point break, so it can handle that size, but keep in mind it’s a fairly consistent spot, so it won’t be a total mystery. After that, it drops back off to small and ordinary again.

The rest of the second week is mostly small, weak, and choppy. A few afternoons clean up, but the swell is just too small to get excited about.

So, if you’re asking me, the only real standout is Friday morning, September 18th. Get there early for the glass, and you’ll find some fun, clean 6ft surf. The rest of the window is a waiting game.

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.
