The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way for the next couple of weeks.
We’ve got a solid run of swell on the cards, but it’s not all smooth sailing. This is a reef break that only an advanced surfer should even think about, and it’s fairly consistent, so there’s always something to keep an eye on. The opening days are a bit of a mixed bag, with some good, clean surf held back by tricky winds or tide windows. The water temperature is sitting at 23°, which is about a degree warmer than usual for this time of year – nothing crazy, but it’s a touch warm.
The real standout comes on Sunday, August 9th. We’ve got a very long period groundswell coming in from the southwest at 18 seconds, pushing 10 ft of swell. That’s proper energy right there, registering a massive 6333 (combined energy). This is expert-only territory – that size is no joke. The morning is looking clean with a cross-off breeze from the southeast at 16 mph. The offshore wind direction for this break is east, so that’s a good angle. It’s a reef break, and with that long period, it’ll be lining up beautifully. Just be aware, crowds are often here, and for a day like this, you can expect it to be busy.
Leading up to that, Wednesday morning the 5th is a write-off for quality, but Thursday morning the 6th has some serious size – 8 ft from the WSW with that same 16-second period – and light cross-off winds from the SSE at 9 mph. Good, clean lines for the experienced crew. The afternoon turns to a cross-shore mess, so get on it early.
After the big Sunday, the swell eases but stays chunky. Monday the 10th is still solid at 8 ft from the southwest, and the morning is clean with moderate cross-off winds. The following week has a few more windows. Thursday the 13th looks promising: 7 ft from the southwest, 16-second period, and a gentle offshore breeze from the ESE at 9 mph. That’s a glassy start to the day. Monday the 17th also has a clean morning with 6 ft from the WSW, and then Tuesday the 18th brings another pulse of 8 ft from the WSW with a 16-second period and clean cross-off winds. By the second week, things get more inconsistent and the winds turn onshore more often, so don’t bank on those afternoons.
There are a few days, like around the 15th and 16th, where the swell drops under 6 ft and the wind is onshore or cross-onshore, making for choppy, poor conditions. A couple of those sessions are a total loss for surfing – more of a kite-surfing setup, to be honest.
Overall, lock in the morning of Sunday the 9th and the morning of Thursday the 13th for the best of the best.
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.
