The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Turtles.
We’ve got a solid 16-day window, but it kicks off with a bit of a mixed bag. The first real standout is Sunday morning the 19th. Turtles is a reef break, so it handles a good swell, and we’ve got a clean 8ft from the WSW with a lovely 15-second period. That’s proper groundswell. The wind is a light cross-off from the SE, keeping it glassy. The water is sitting at 74°, which is about normal for this time of year. The energy is pumping at 3162 (moderate to strong). This is for the advanced crew only – it’s a proper session.
After that, things get messy. Monday and Tuesday are a write-off with strong winds and poor surf. Wednesday the 22nd offers a bit of a cleaner look with a 5ft SW swell and cross-off winds, but it’s not setting the world on fire.
Then we get a glimpse of something better on Thursday the 23rd. The morning brings a 5ft SW swell with a 16-second period, and we get offshore winds from the East at 35 km/h. The energy is 1179 (moderate). It’s a bit windy, but those offshore conditions will keep it clean. That afternoon cleans up even more with a lighter offshore breeze and a 5ft swell. Worth a look for the crew.
The second week is a roll of the dice. The end of July and start of August has a big pulse showing. Friday the 31st of July morning is a serious one: 12ft of WSW swell with a 17-second period, and clean cross-off winds. The energy is 7229 – that’s strong. This is a big wave day for experts only. It’s a long way off, so keep an eye on it.
August 1st Saturday morning is a similar story – 10ft of WSW swell, clean, and massive energy at 3773. Again, this is for the top-tier surfers.
A quieter but promising session shows up on Wednesday the 29th of July morning. Glassy conditions with a 3ft, 19-second period WSW swell. The energy is 1259 (moderate). That’s a long period, so it will be a clean, powerful little wave at the reef. Perfect for a more relaxed session if you’re not keen on the big stuff.
Overall, the best bet for the average surfer is the Thursday the 23rd for a clean, offshore session. For the big wave hunters, the Friday the 31st and Saturday the 1st are the ones to watch, but they are a long way out.
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.
