The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a solid window opening up, but you’ve got to be patient. The first few days are a bit messy with onshore winds and questionable conditions, but the real action starts to build from Thursday morning onward. The standout period is going to be Wednesday morning, August 5th, and the following Monday morning, August 10th. Those are the ones to circle on the calendar.
The only break in the game for this whole stretch is Turtles, a reef setup that handles a fair bit of swell. The water temp is sitting at 73°, which is about average for this time of year, so nothing wild there.
Let’s start from the beginning. Tuesday, July 28th afternoon is a write-off – onshore wind, messy, and the wave energy is actually pretty strong (1028) but the quality is just not there. Wednesday morning, July 29th is a different story. You get a light NNE breeze, cross-offshore, and clean lines. Swell is 5 ft from the SW, with a period of 14 seconds, pushing a solid 1318 units of energy. This is a good session for experienced surfers, but it’s not the best of the run.
Thursday morning, July 30th is also clean, with a 5 ft SW swell and a longer period of 16 seconds (1062 energy). That longer period gives the waves more shape and punch, but it’s still a bit below the big stuff. Thursday afternoon, the wind swings SW at 15 mph, cross-on, and it gets choppy – forget it.
Friday morning, July 31st is clean again with a cross-offshore breeze, 4 ft SW swell, and 14 seconds (1235 energy). But Friday afternoon is another mess with strong cross-on winds. Saturday, August 1st morning has a 7 ft WSW swell with 16 seconds (2102 energy), clean conditions, but the wind is a moderate cross-offshore. Saturday afternoon is cross-shore and a bit lumpy.
Sunday, August 2nd morning is clean with a 6 ft SW swell (1396 energy), but the wind is a moderate cross-offshore. Sunday afternoon, the wind goes cross-on and it’s choppy again.
Now, the first true standout is Wednesday morning, August 5th. We’ve got a 7 ft WSW swell, a 16-second period, and the energy is pumping at 2450. The wind is SE at 3 mph, practically glassy, cross-offshore. This is as clean as it gets for a reef break. The waves will have serious power, and with that long period, it’s going to be a proper groundswell. For experienced surfers, this is the session to aim for. Keep in mind, with that size, it’s not for beginners.
Thursday, August 6th morning sees a 8 ft WSW swell with a 17-second period (3315 energy), but the wind is cross-shore, creating a bit of chop. It’s still surfable, but not as perfect as Wednesday.
The next big one is Monday morning, August 10th. Another 8 ft SW swell, 17-second period, and the energy is massive at 3548. The wind is SE at 15 mph, cross-offshore, so it’s clean. This is a powerful, long-period swell. For a reef break like Turtles, that’s a dream – the wave face will be long and lined up. Again, this is for experts only at that size. The crowd factor at Turtles is “often,” so expect company.
The run then drops off. Tuesday, August 11th morning has a 6 ft SW swell with a 14-second period, and a light offshore breeze from the ESE. Clean, but a step down. Wednesday, August 12th morning is small, just 3 ft, and then it’s all onshore wind and choppy junk after that.
So, to sum it up: the best bets are Wednesday morning, August 5th, and Monday morning, August 10th. Big, clean, powerful groundswell. The rest of the time is either average or poor. Get it while it’s good.
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.
