The Lowdown
Alright crew, Rusty here. Let’s break it down. We’ve got a solid run of surf on the cards, but it’s not for everyone. The standout break is Turtles, a proper reef setup. Water temp is sitting at 73°F, which is about average for the time of year, so no surprises there.
The first real opportunity kicks off Friday, July 31st, with the morning session. We’re looking at a clean 4ft swell from the SW, with a light cross-offshore breeze from the SE. It’s only for the experienced crew though, as the energy is already pumping at 1235 (moderate). The wind is light, so expect it to be clean.
That Friday afternoon goes a bit sideways with the wind swinging onshore, turning things choppy. Not worth your time.
Saturday, August 1st has a bit more size at 7ft in the morning, and it’s clean, but the wind is up at 16 mph from the SE. It’s surfable if you're skilled, but the quality is just okay.
Now, Sunday, August 2nd is where we get a proper window. Morning glass-off with a true offshore breeze from the ENE at just 9 mph. The swell holds steady at 6ft from the SW, period a solid 15 seconds. This is excellent for experienced surfers. This is your pick of the first week.
The middle of the week gets messy with onshore winds and building swell. Monday, August 3rd has some rain showers and strong cross-off winds, but it’s not the best.
From Thursday, August 6th through the weekend, we see a big pulse. Swell sizes jump up over 8ft and even hit 12ft by Saturday, August 8th. But the wind is all over the shop—mostly onshore and strong. It’s big and powerful (combined energy over 5000 on the 8th), but messy. This is expert-only territory and honestly, the conditions are poor.
We get a bit of a breather by Friday, August 7th morning, with a clean 7ft swell and light cross-off wind. Good for the brave.
The real standout of the whole outlook, though, is the run starting Wednesday, August 12th. Morning brings a massive 13ft SSW groundswell with an 18 second period. That’s a very long-period groundswell, and at a reef like Turtles, that spells power. The wind is offshore from the SE at 19 mph, keeping it clean. Combined energy is a staggering 9091. This is a heavyweight session, only for the most experienced. Thursday, August 13th holds similar size and also clean with offshore winds. And then Friday, August 14th morning might just be the pick of the entire 16 days: clean 8ft swell, but the wind goes glassy from the E at just 3 mph. Absolutely no wind. That’s as good as it gets at this level.
After that, the swell backs off a touch but stays in the 8ft range through the weekend of the 15th and 16th, though winds turn more cross and onshore, making it less inviting.
Overall, the first week is good for a few clean windows, but the second week from August 12th onward is where the heavy-hitters need to be ready. It’s big, it’s clean, and it’s all for the experts. Crowds are likely at Turtles, but on a day like that, you won’t care.
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.
