The Lowdown
Alright, Rusty here, checkin’ in on Turtles. We got a solid run ahead, but it’s two different stories. The first week is clean and powerful, then the second week goes huge.
Sunday the 19th, right off the bat, we’ve got a solid 8 ft swell from the WSW, with a very long 15-second period. The wind is a light cross-offshore from the SE, so the face is gonna be clean. The water is 74°, which is about average for this time of year. The combined energy is pumping at a strong 3162. This is a reef break for advanced surfers only, and it’s often crowded here. The quality is too good to pass up.
Monday the 20th drops to 7 ft from the SW, with a 13-second period. The wind picks up to a fresh 19 mph from the SSE, so it’ll be a bit bumpy. The energy is moderate at 1602.
Tuesday the 21st drops to 4 ft. The wind is still fresh. Not the best, but the morning is clean. Wednesday the 22nd the wind swings offshore from the ESE at 19 mph, cleaning up the 5 ft swell. Thursday the 23rd is a standout. The swell pushes back to 5 ft from the SW, but the period jumps to 16 seconds. That’s a very long period groundswell, and with a fresh offshore wind from the E at 19 mph, it’s gonna be glassy. The energy is moderate at 1281. Perfect for a reef.
Friday the 24th drops to 4 ft, still offshore. A good day for a log. The weekend of the 26th and 27th is small and a bit onshore, so not worth it.
Now, the big show. Monday the 27th, the swell picks up to 6 ft from the WSW with a 16-second period. The wind is light. Energy is strong at 1373. Tuesday the 28th holds similar size.
The real story is the first few days of August. Saturday the 1st of August, we’re looking at a massive 13 ft swell from the SW with a 16-second period. The combined energy is a whopping 6984. This is expert-only. The wind is a cross-offshore from the NE at 19 mph. Sunday the 2nd of August is similar, 12 ft from the WSW with a 17-second period, energy at 6680. This is the big one. It’s a long way out, but if it holds, it’s the standout.
After that, Monday the 3rd of August settles to 7 ft, still rideable but the wind gets a bit onshore.
For the experienced crew, hit Sunday the 19th and Thursday the 23rd. If you’re a charger, watch Saturday the 1st and Sunday the 2nd of August. That’s a proper big-wave session.
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.
