Table - best surf conditions forecast for Turtles over the next 16 days.
Right, let’s have a look at what’s cooking for the next couple of weeks. The only real player on the board is Turtles, a reef break that only works for advanced crew. It’s a fairly consistent spot, but it’s often crowded and it’s wide open to the swell, so it takes a solid hit. The optimum swell direction is SSW, so we’ll be watching that.
The water temp is sitting at 74° right now, which is about average for the time of year—nothing unusual there.
We’ve got a bit of a wait for the first real window. Saturday afternoon is a write-off: cloudy, cross-on wind, choppy mess. For the first decent surf, we’re looking at Sunday morning, July 12th. It’s clean with a cross-off breeze, and a 5ft SW swell coming in at 14 seconds – that’s a proper groundswell. The combined energy is moderate (946). It’s a solid start, but the swell isn’t huge yet.
The real standout is Monday morning, July 13th. Offshore wind, light breeze, and the swell jumps to 7ft from the SW, period stretching to 18 seconds – that’s very long-period groundswell. The energy is strong (2706). This is a serious wave for experienced surfers. The reef setup will handle that long period perfectly, so expect some proper, well-shaped walls. The afternoon gets messy with cross-on wind, so get in early.
Tuesday morning, July 14th is another cracker. Offshore wind again, 6ft SW swell at 16 seconds, and strong energy (1816). Another clean, powerful morning for the advanced crew.
Wednesday morning, July 15th keeps the run going with offshore wind, 6ft WSW swell at 14 seconds, and moderate energy (1168). Clean and fun.
The next big highlight is Saturday morning, July 18th. It’s a clean cross-off, but the swell is 7ft from the WSW at 19 seconds – very long period. The energy is strong (3417). That afternoon the swell builds to 10ft from the SW, but the wind goes cross and it gets lumpy. The morning session is the one for experts only.
Sunday, July 19th sees the swell holding at 8ft from the WSW and SW, with clean cross-off winds all day. The energy is very strong (3196 in the morning, 3269 in the afternoon). This is a solid, powerful groundswell for the experienced.
Thursday morning, July 23rd shows a building swell again: 6ft SW at 16 seconds, cross-off wind, strong energy (2468). But the afternoon turns onshore and messy.
The final standout is Friday morning, July 24th. Offshore wind, 8ft SW swell at 16 seconds, and very strong energy (2875). Another big, clean morning for experts.
After that, the surf drops off and the winds get messy, with a small window of glassy conditions on Wednesday afternoon, July 22nd – 5ft SW swell, glassy wind, but it’s a short-lived pocket.
If you’re an advanced surfer, the best two calls are Monday morning, July 13th and Friday morning, July 24th – both have offshore winds, solid SW groundswell, and strong energy. The reef will handle the long period well. Just be aware, Turtles can get crowded.

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.
