The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the table for Turtle Cove.

Right off the bat, I gotta be straight with you – it’s a tough start. For the first few days, we’re looking at nothing but tiny, weak energy and poor conditions. From Wednesday the 12th right through the weekend and into the early part of next week, the swell is mostly below 2ft, with the combined energy struggling to hit even 34 (really weak). The wind is all over the shop, often putting a chop on it, so it’s just not worth paddling out. You’re looking at a stretch of nearly five days with nothing to get excited about.

Now, things finally get a little interesting on Monday the 17th. The morning brings a bump in swell to 5ft from the SSW, with a combined energy reading of 246 (moderate). The wind is cross-off from the NW, so the face should be pretty clean. The period is only 8 seconds though, so it’s a bit of a short-period wind swell, not a classic groundswell. It’s a marginal call, but it’s the best we’ve seen so far. The afternoon drops off a bit.

Tuesday the 18th morning looks surprising – the wind goes glassy, which is a rare treat. The swell is back down to a tiny 2ft from the S, with energy at only 68 (weak). It will be clean as a whistle, but you’ll be scratching for any kind of push.

The real standout in this whole 16-day window looks to be the morning of Wednesday the 19th. We get a 3ft SSE swell with a period of 11 seconds – that’s a proper groundswell. The combined energy hits 139 (moderate). The wind is light cross-off from the WSW, so the waves should have some shape and be pretty clean. Turtle Cove is a reef and point setup, and an 11-second swell from the SSE will work nicely there, wrapping in with some decent lines. This is the pick of the bunch.

After that, we go back into a funk. The rest of the week and into the next is mostly poor, with strong winds and messy conditions. There’s a weird spike on Saturday the 22nd with a 6ft SSW swell and energy of 406 (strong), but the wind is howling from the SSW at 15-18 mph, making it a cross-off that will be too blown out to enjoy. That size is also pushing into expert-only territory if it’s closing out.

The very last session on Wednesday the 26th afternoon might offer a small reprieve with glassy conditions and 3ft from the ENE, but the energy is weak at 77.

Water temp is about average for this time of year, nothing unusual.

So, to sum it up: the first week is a write-off. Your best bet is the morning of Wednesday the 19th. It’s not a big swell, but it’s the cleanest, most lined-up option we’ve got. Don’t expect a crowd out there, as it’s a fairly consistent spot but the conditions have been so poor. Get on it early.

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.
