The Lowdown
Alright folks, Rusty here again. Let’s break down what’s cookin’ at Turtle Cove. It’s a reef and point, open to the swell, and the water’s hangin’ at 69°F – that’s a bit cooler than usual for this time of year, down by 3°F.
Right off the bat, we’re gonna have to wait. Wednesday the 29th is a total washout – a strong, cross-on wind and a lumpy 6ft swell with a short period – just a mess. The combined swell energy is moderate, hitting 273, but it’s not worth paddling out for.
Thursday the 30th morning shows a little improvement. The swell drops to 4ft, but the wind swings light and cross-off, leaving the surface clean. The period stretches to 9 seconds, a bit more friendly. Energy is still moderate at 264. It’s rideable, but nothing special. Friday and Saturday stay small and weak, with energy down in the low hundreds – just a 3ft to 3ft leftover.
We hit a real flat spell from Sunday the 2nd into the middle of the following week. Energy bottoms out at 11, and wave heights drop below 2ft for a few days. That’s a solid stretch of nothing.
Now, here’s the one to circle. Sunday the 9th of August. Early morning, we’ve got a clean 7ft swell from the SSW with a light offshore wind from the WNW – that’s glassy goodness. The energy jumps to 365 (solid moderate). By the afternoon, the swell pushes to 7ft, the wind stays offshore, and the energy hits 476. That’s a powerful, clean, chunky day for the reef. This is the standout – it’s expert territory, too big for the beginners. The period is 7 seconds, so it’s a short-interval swell, but the offshore wind will keep it clean and lined up.
After that, Monday the 10th and Tuesday the 11th still have some size (5ft to 5ft), but the wind gets fiddly – cross-shore and cross-on – making it a gamble. The energy stays moderate, up to 496. Then it fades again into small, weak surf for the rest of the second week.
Bottom line: the first week is mostly a dud except for a few small, clean hits. The real deal is that Sunday the 9th of August – big, clean, offshore. Get on it if you’ve got the nerve. The rest is mostly small or blown out.
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.
