The Lowdown
G’day, I’m Rusty, and here’s the outlook for the region.
We’ve got a 16-day window, but the first couple of days are a write-off—nothing worth paddling out for. The first real action kicks off Thursday morning, 16 July, and from there, it’s a slow build with a couple of standout windows.
The only break on the cards is Turtles, a reef setup that’s fairly consistent but only for advanced surfers. The water temp is sitting at 74°, with a 0.9° anomaly—pretty much average for the time of year, so no shock to the system.
Thursday morning, 16 July is the first clean session. You’ve got a 4ft swell from the WSW, with a period of 14 seconds—that’s long-period groundswell, meaning better shaped waves but longer lulls between sets. The wind is NNE at 16 mph, cross-off, so it’s clean. Combined energy sits at 913 (moderate). It’s a solid warm-up, but not the standout.
Sunday morning, 19 July is the big one—this is the pick of the entire forecast. Swell jumps to 8ft from the WSW, with a period of 16 seconds. That’s a very long-period groundswell, packing a punch (combined energy of 3203—strong). This is expert territory only; too big for beginners. Wind is SE at 6 mph, cross-off, and it’s clean. The break is exposed to the SSW, and the swell direction is WSW, which is close to its optimum. This is the day to clear your schedule.
Wednesday morning, 22 July is another solid call. 5ft from the SW, 14-second period, combined energy of 1092 (moderate). Wind is E at 12 mph, offshore, and it’s clean. Good for experienced surfers, and the offshore wind will make it glassy.
From there, the surf tapers off. The second week (starting 23 July) has smaller, cleaner windows—like Thursday morning, 23 July with 5ft from the SW, 12-second period, and ENE wind at 19 mph, offshore and clean (combined energy 624). But it’s not the juice of the first week.
The last real chance is Thursday morning, 30 July—5ft from the WSW, 19-second period (very long period), combined energy 1536 (moderate). Wind is SE at 16 mph, cross-off, clean. This one’s promising but further out, so less certain.
Expect crowds at Turtles—it’s marked as “often” busy, so get in early, especially on that Sunday.
Stay stoked,
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.
