The Lowdown
Alright crew, Rusty here again with the same outlook, but in the old-school numbers.
We've got a solid, consistent run of SW groundswell heading for Turtles, but the wind is going to be the deciding factor. You'll need to be on your game to score the best of it.
The first chance to paddle out is on Sunday the 19th. The swell is already a solid 8ft from the SW, with a 15-second period, so there's plenty of juice (2491). The cross-shore wind will mess with the face a bit, though. It's doable, but not perfect.
The wind cleans up nicely for Monday morning the 20th. We're looking at a clean 7ft SW swell with a 13-second period and a cross-offshore breeze. This is a proper session for the advanced crew. The energy is still strong (1460), so those waves will have some serious push.
The real standout, the one to plan around, is Thursday the 23rd. The wind goes offshore from the East, the swell is 5ft from the SW, and the period is a massive 16 seconds. That's a long-period groundswell, and the energy reading (1281) confirms it's packing some heat. The afternoon gets even better with a moderate offshore breeze. This is a high-quality day for experts, but that long period will mean big, clean lines at this reef. Expect some sets.
After a few smaller days, the next big pulse hits Monday the 27th. The morning is looking excellent for the experienced crew. We're back to a 5ft SW swell with a 16-second period and a gentle offshore breeze from the ESE. The water will be clean and the energy is back up (1407). The afternoon turns into a messy cross-onshore, so it's a dawn patrol job.
Into the first week of August, the pattern holds. Saturday the 1st has a clean afternoon session with light winds and a 4ft WSW swell, with solid energy (1250). It'll be fun and clean. Sunday the 2nd has a bigger 7ft swell, but the wind goes onshore in the afternoon.
Water temp is sitting at 74°, which is pretty normal for this time of year.
Remember, Turtles is for advanced surfers only. When the swell pushes over 8ft, like the Monday afternoon on the 27th, it's big and powerful. When it's under 5ft, it's still a reef with some punch. The crowds are often a factor here, so expect some company on the peak. This spot is fairly consistent, so the flat spells won't last long.
This is Rusty, signing off.

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.
