The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe. We’ve got one spot on the radar for the next 16 days, and it’s a proper advanced reef break that’s going to see plenty of action.
We’re looking at Turtles, a solid reef setup that’s fairly consistent and exposed to the south-southwest swell. The water’s sitting at 73.6° with a slight positive anomaly, so it’s a touch warmer than usual for this time of year, but nothing crazy. The best swell direction for this spot is a south-southwest, and we’ve got a long run of west-southwest and southwest groundswells coming through, which lines up nicely.
The first proper surf kicks off on Tuesday the 4th of August. It’s a slow start with a 4.3ft west-southwest swell at 16 seconds, but the wave energy is already pumping at 1041. The wind is a cross-off from the northeast at 15.5 mph, so it’ll be clean but not firing on all cylinders. The score is a bit low, so I wouldn’t rush out for this one.
Come Wednesday the 5th, things ramp up. The morning sees a 7.5ft west-southwest swell with a 16-second period, and the energy jumps to 2648. The wind is a cross-off from the east-southeast at 12.4 mph, so it’s clean. But the real standout is Wednesday afternoon: a 7.2ft south-west swell, 16-second period, and the energy is 2291. The wind shifts to a light cross-off from the south-southeast at just 6.2 mph, making for glassy conditions. This is the pick of the first week—excellent surf for experienced surfers, clean, and with that long-period groundswell powering in. The only downside is that crowds are possible, so get in early.
Thursday the 6th keeps the momentum. The morning is a big 8.2ft west-southwest swell at 16 seconds, with energy at 3548. The wind is a gentle cross-off from the south-southeast at 9.3 mph, and it’s clean. Thursday afternoon is even better—same swell size and period, but the energy hits 3565, and the wind stays light. That afternoon session is another top contender, with the score peaking at a 5. It’s still expert territory at over 8.2ft, but the conditions are dialled.
Friday the 7th sees the swell holding at 7.2ft, but the wind turns cross from the south at 9.3-12.4 mph, bringing a bit of chop. It’s not the day for perfection. Saturday the 8th is a write-off—strong south winds at 21.7 mph, lumpy cross-shore chop, and poor surf. Don’t bother.
Sunday the 9th is a big one. A 9.8ft south-west swell at 17 seconds rolls in, with energy at a massive 5677. The wind is a cross-off from the southeast at 18.6 mph, so it’s clean but windy. This is a heavy, powerful groundswell with a very long period, so it’s only for experts. That long period will make it a bit straight at a beach break, but on a reef like Turtles, it’ll be a proper freight train.
Monday the 10th drops off slightly to 7.5ft, but the wind stays fresh from the southeast. It’s still clean, but the energy is lower. Tuesday the 11th brings a strong offshore from the east-southeast at 24.9 mph, with a 6.2ft south-west swell. The wind is strong offshore, making it clean but hard to paddle into. This is a session for the confident crew.
The real standout of the entire forecast is Wednesday the 12th of August. The afternoon brings a 6.2ft south-west swell at 16 seconds, with energy at 1970. The wind is a moderate offshore from the east-southeast at 15.5 mph, and it’s clean. The score hits a 4, and the conditions are described as excellent for experienced surfers. That moderate offshore wind is the key—it’ll hold the face open and make for some sweet, hollow waves.
Thursday the 13th to Saturday the 15th sees a mix of conditions. The swell stays around 5.6ft to 6.9ft, with some cross-off and light winds. Saturday the 15th morning is a nice one: a 5.6ft south-west swell, 15-second period, energy at 1376, and a light cross-off from the north-northeast at 6.2 mph. Clean and excellent for experienced surfers.

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.
