The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a bit of a slow start, but some real gems are lining up, especially for the crew who can handle a bit of size.
The early part of the forecast is pretty average. Friday the 17th and Saturday the 18th are a write-off. The swell is there at 5ft to 6ft, but the wind is all over the shop, making it messy and choppy. The combined energy is moderate (819 to 1473), but it’s not doing anyone any favours. You’d be better off waiting.
Then things get interesting. Sunday the 19th morning is the first real standout. Turtles is an advanced reef break, and this is its time. We’re looking at a solid 8ft swell from the WSW, with a very long period of 15 seconds. That’s proper groundswell energy (3037). The wind is a light offshore breeze from the ENE, so it’s going to be clean. This is excellent surf for experienced surfers. The water is sitting at 74°, which is about normal for this time of year. Just a heads-up: with this kind of long-period swell, it can be a bit straight at beach breaks, but on a reef like Turtles, it’ll be cranking. This spot is fairly consistent, and often has crowds, so expect some company.
Monday the 20th is a weird one. The morning is a complete mess with a strong crosswind, but Monday afternoon the wind drops to glassy conditions. The swell drops a touch to 5ft from the SW (13-second period) with moderate energy (923), and it’ll be clean. It’s a chance for a few if you can get out of work.
After Monday, the swell drops off and the wind stays strong for a few days. Tuesday the 21st through to Wednesday the 24th are dominated by fresh onshore or cross-off breezes, and the swell is inconsistent and small. It’s a poor run for the most part, with combined energy dropping under 1000. There’s a brief moment on Thursday the 23rd morning with a fresh offshore wind and a 5ft SW swell, but it’s marginal.
The real next big invite comes on Wednesday the 30th of July. The morning looks excellent for experienced surfers. We’ve got a 7ft swell from the WSW, with a very long 17-second period, and the combined energy is strong (2404). The wind is a slight cross-offshore breeze, so it’ll be clean. This is a big, powerful groundswell that needs a reef like Turtles to really shine. It’s a promising long-range call.
Thursday the 31st morning is also a cracker. Another 7ft from the WSW, 17-second period, and a light cross-offshore breeze. The energy is even higher (2488). This is another excellent session for the experts. The afternoons, however, are likely to be blown out.
For the first week of August, the swell starts to back off a bit. Saturday the 1st morning has a 6ft WSW swell with a 16-second period, clean enough with a cross-offshore breeze, but it’s not the same level as the earlier standouts.
Overall, the best on offer is definitely Sunday the 19th morning, and the standout week-long window is the 30th and 31st of July mornings. The rest of the time, it’s a waiting game or a fight with the wind.
Rusty.

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.
