The Lowdown
Alright, Rusty here. Let's have a look at what's on offer at Turtle Cove (Turtle-Cove) over the next couple of weeks.
Honestly, looking at this 16-day window, it's a real mixed bag and mostly a frustrating one. We've got a solid run of small, weak, and pretty average swell with cross-off winds messing with the shape. There are no true standouts, just a couple of windows where the conditions are less ordinary.
The water temp is sitting at 69.3°, which is a bit colder than normal for this time of year – you'll feel that chill on the paddle out at Turtle Cove. The combined wave energy is almost always in the low double digits, topping out at a moderate reading on the 9th of August, but for the most part, we're looking at weak, unenergetic surf.
Here's the rundown. Starting from Thursday the 6th of August, it's small – 1 ft of short-period SE swell with a moderate breeze. Poor surf. That theme carries through to Friday the 7th. Friday morning actually has a touch of size at 3 ft from the SSW, but with a period of just 6 seconds, it's weak and disorganised. The combined energy is still weak. The wind is cross-off, making it messy. It's surfable, but very ordinary.
Saturday the 8th and Sunday the 9th are more of the same. Sunday morning sees the swell bump up to 3.6 ft with at least moderate energy, but that short 6-second period and cross-off wind mean it's poor. Monday the 10th drops back down. We get a little glimmer on Wednesday the 12th with a 3 ft SSW swell and a very light wind, but the period is still a weak 6 seconds. Again, just very ordinary.
The end of the first week and into the second week, from the 13th of August, the wind finally swings offshore from the W and WSW. That's good news for cleanliness. However, the swell remains tiny and weak, generally around 1.3 ft to 2 ft with periods of 6 seconds. The energy is weak. You might get a clean little wave if you're desperate, but there's no power. Friday the 14th afternoon has a weird spike of 3.6 ft from the NNE with a 4-second windswell period – that's just windchop.
The only moment that even gets a pulse is Wednesday the 19th of August. The afternoon sees a moderate offshore breeze from the W and a 5 ft SSW swell. The combined energy is moderate. It’s the biggest swell of the 16 days. But with a 6-second period, it's a short, dumpy wave. It's not going to be pretty. For an intermediate surfer, it's probably the best of a bad bunch, but it's still poor. After that, we're back to tiny and weak for the rest of the run until the 21st.
So, there's really nothing to get excited about. The conditions are mostly poor, the swell is tiny, and the energy is weak. If you absolutely have to get wet, the 19th of August afternoon might offer a grovelly, clean high-tide wave with the offshore wind, but keep expectations low. Otherwise, it's a bit of a dud forecast.

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.
