The Lowdown
Alright folks, Rusty here. Let’s break it down. We’ve got a solid run of surf coming up at Turtles, a reef setup for the advanced crew. The water is sitting at 74°F which is a touch warmer than normal for this time of year, about a degree above the long-term average. The first day we can get in the water is Thursday the 6th. It’s not perfect, but there’s a decent, consistent, long-period groundswell from the WSW pushing in at 8ft with a 16-second interval. The energy is strong—right in the moderate-to-strong zone (3548). The issue is that wind is cross from the south at 9 mph, so expect a slight cross-chop. It’s surfable, but not the pick of the window. By Friday morning the 7th, we get a cleaner setup. That swell drops a touch to 7ft from the WSW, still with that lovely 16-second groundswell pulse, and we get light cross-offshore breeze from the southeast at 6 mph. That’s clean, with nice energy (2488). This is the standout early in the run. The reef should be lining up beautifully for experienced surfers. Saturday the 8th gets messy with strong cross-shore winds, so skip that.
Sunday the 9th brings a serious jump – a 10ft SW swell with a 17-second period. The energy is very strong (6261). The wind is cross-off from the southeast at 19 mph, keeping things clean despite the size. This is a big one – over 8ft, so expert territory only. That long period will make it a bit straight at a beach break, but at a reef like Turtles, the shape should be there.
We then have a long run of good, clean morning windows through the middle of the month, with swell holding in the 7ft to 8ft range from the SW, and periods staying solidly in the groundswell territory. The standout during this stretch is Wednesday morning the 12th. The wind goes true offshore from the ESE at 22 mph, with a 10ft SW swell and a 16-second period, energy at 4209. That’s clean, powerful, and offshore – absolute classic conditions, but only for the experts.
The later part of the run, from the 16th, we get a drop in size. Monday the 17th morning is a nice option for a slightly tamer session, with clean cross-off wind and 8ft at 14 seconds from the WSW. It’s still a fair-sized wave. Then Thursday the 20th morning looks promising again, with an 8ft WSW swell, 17-second period, strong energy (3949), and clean cross-off breeze.
If I had to call the two true standouts: Friday morning, August 7 for the cleanest, well-shaped, powerful groundswell for advanced surfers, and Wednesday morning, August 12 for the serious, offshore-blasted, big-wave session for experts only. Crowds are often a factor at this break, so get out early.
Right, that’s the picture. The swell energy is moderate to strong all the way through, so there’s plenty to work with. Stay safe out there.

Information about the Turtles Surf forecast
The above surf forecast table for Turtles provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Turtles can be found by selecting the local surf guide option on the grey menu. Our Turtles 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 (Turtles) 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 Turtles 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.
