The Lowdown

Alright, let me level with ya. I've had a look at what's on the table for Turtle Cove over the next couple of weeks, and I gotta tell ya, it's a bit of a rough stretch. We've got one tiny window where things might get interesting, but for the most part, this is a waiting game.

Right now through the end of September, it’s pretty flat. We're talking tiny, weak swells mostly under 2 ft, with combined energies barely cracking 50. That's barely a ripple. The water temp is sitting at a pleasant 69°F, which is bang on average for this time of year, but there's just no push to back it up.

The story starts to change a little around Sunday the 20th. We see a jump to a 3 ft SSW swell, but with a short period of only 6 seconds and a nasty cross-onshore wind, it's gonna be a choppy, messy affair. Not worth paddling out for.

Now, here’s where I get a little excited but have to keep my feet on the ground. From Monday the 21st right through Wednesday the 23rd, we've got some real size building. The swell jumps to 5 ft from the East on the 21st and 22nd, pushing combined energy up over 200 – that's moderate energy. But the real kicker comes on Wednesday the 23rd, with a 7 ft ESE swell. That's a solid 489 of combined energy, strong stuff. This is the standout period, but there's a huge catch.

The wind is a total killer. For the 21st and 22nd, it's onshore or cross-onshore East winds at 12-16 mph. That's gonna chop it up bad. On the 23rd, it's a fresh cross-onshore from the SSE at 19 mph. For a reef and point break like Turtle Cove, that wind direction will ruin it. The waves will be lumpy, messy, and closed out. If the wind had been offshore, this would have been a day to call in sick for work.

Now, by Thursday the 24th, the wind finally swings cross-off from the SSW at 22 mph, cleaning it up beautifully. The swell drops to a still-chunky 6 ft (572 combined energy), but those strong winds and long period will make for incredibly clean, powerful lines. This is actually a very interesting prospect for expert surfers who can handle the paddle out. The swell direction from ESE is a little off the optimum SE for Turtle Cove, but with that glassy wind, it might just wrap in nicely.

After that, it drops off fast. By Friday the 25th we're back to small, weak, and choppy. The whole run from the 14th to the 19th is a write-off. You're looking at over a week of flat, unrideable conditions. It's a tough outlook, but that's the way it lays down sometimes.

So, if you’re an experienced surfer who can handle big, clean water, Thursday the 24th is your only real shot. For everyone else, you might as well save your energy and wait for the next proper swell.

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.
