The Lowdown

Alright mates, Rusty here. Let's get one thing straight from the jump: this forecast is a marathon, not a sprint. We've got a long window ahead with a lot of grovelly, weak surf before things get serious. It's all about patience, and we're gonna need a heap of it.

The first stretch is woeful. We're talking tiny, dribbly waves barely pushing past a foot or so. The wind is mostly offshore or cross-off, which would be a dream if there was any power behind it. The water temp is around 69°F, standard for the time of year, nothing special. The first few days are a total loss, just clean but completely flat. You could water-ski on it.

As we roll through the first week, the pattern stays weak. One pulse on Sunday looks like it wants to push the swell to a few feet, but it’s steep and jumbled. It’s the kind of surf that gives you hope for half a second before you realize it’s a closeout mess. Then we hit a total lull, a period of a few days where the ocean just goes to sleep. It's a real desert out there, with no energy at all. The combination of the break being consistent but the swell being absent makes it feel worse.

But then... the light at the end of the tunnel. The final Thursday throws a serious spanner in the works. A powerful, long-period swell from the south-southeast is forecast to roll in, ramping the surf up to a solid double-overhead plus. The raw energy in the water is incredible, going from a few hundred to a five-figure reading in a day. It’s a huge, legitimate groundswell.

Here's the kicker, though. The wind sits cross-shore, chopping up what could be a perfect day. The size is already in the expert-only territory, and with the bump on top, it’s only for the brave. But, the direction is spot on for Turtle Cove. It has the exact open, south-facing exposure to grab every bit of that SSE energy. It’s a shame the wind isn’t offshore, but even so, this is the standout of the entire 16 days, though the forecast confidence is still a question mark this far out. For the crew willing to fight the crowd and the chop, you might get a very memorable, proper slab. But keep your expectations in check for the rest of the run.

Rusty, signing off.

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.
