The Lowdown
Alright folks, Rusty here. Let’s paddle out into this forecast for Turtles. It’s a solid reef break, advanced territory, and it’s fairly consistent, so it’s not gonna be flat for long. We’ve got a run of decent swell coming through, but winds are going to be the main character here.
The water is sitting at 74°, which is about average for the time of year. The first few days of the period are a bit of a write-off. Monday the 3rd is a mess with strong onshore winds and the swell is messy. Not worth getting wet.
Things start to turn around Tuesday the 4th. The morning brings a 4 ft WSW swell with a 16-second period – that’s nice long-period groundswell. The wind is offshore from the east at 16 mph, and that’s a major positive. It’s clean, it’s glassy. The combined energy is moderate (1041). This is a solid option for the experienced crew. The best part of the week is shaping up Thursday the 6th morning. We’ve got an 8 ft WSW swell, still with that 16-second period, and clean cross-offshore winds from the SSE at 9 mph. The energy is kicking into high gear (3548). That’s a standout morning – big, powerful, and clean. It’s big for a reef, so only for the experts.
The weekend of the 9th and 10th sees a bump in size. Sunday the 9th morning is pushing 10 ft from the SW, 16 seconds, but the wind is a fresh 19 mph cross-offshore. It’s clean, but the energy is massive (4168). That’s a serious, heavy swell. The 12th of August, a Wednesday, is another standout. The morning shows a 10 ft SW swell with a 17-second period, and the wind is a clean offshore from the east at 22 mph. The energy is through the roof (5587). That is a powerful, clean, expert-only session. The last real highlight is the morning of the 18th of August. We’ve got an 8 ft WSW swell, 16 seconds, and light cross-offshore winds from the southeast at 9 mph. The energy is strong (3113), and it’s clean. A great way to bookend the period.
Because this is a reef break, that long-period swell is going to shape up nicely, but it’s not a beginner zone. Crowds are often there, so expect company for the best windows. The afternoon of the 10th and the 11th are a total loss with strong winds and poor surf.
Overall, the best on offer is the morning of the 12th of August. That deep, long-period SW groundswell with clean offshore wind is the true standout. The morning of the 18th is a close second.
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.
