The Lowdown
Alright, let’s get to it. First up, we’ve got a bit of a wait on our hands. The surf over the next few days is pretty lackluster, to be honest. The swell’s there, but the wind’s got it all chopped up and messy. You’ll see some waves on Monday afternoon at Turtles, but it’s cross-on and lumpy, a proper waste of that 6.5ft of WSW swell. The energy is strong, (2096), but it’s just not clean.
The rest of the week stays in that same vein. Tuesday morning is a bit better, with a cross-off breeze giving you some cleaner 5.9ft lines, but it’s still a tough paddle for not much reward. The afternoons are blown out again, and the wind stays fresh from the south, making things lumpy. The swell slowly drops into Wednesday, down to 4.6ft, but the wind, particularly in the afternoon at 25 mph, just ruins any chance of a good one. You’re looking at a few days of onshore crumble more than anything. Thursday sees the swell pick up again, but it’s still cross and rough. We’re in a bit of a shoulder-hopping, take-what-you-can-get pattern for the first week. The period’s around 13-14 seconds, so there’s some push, but the wind just won't give us a break.
Now, looking further out, that’s where the real interest lies. The big standout is looking like the morning of Monday the 7th. The swell is going to be pushing 9.8ft from the SW, and with a 17-second period, this is proper groundswell. The energy reading is massive (4380). The wind is a moderate cross-off from the SE, which means it should be clean and holding shape. Now, this is a reef break, so that long-period swell is going to focus nicely. It’s an advanced spot, and with that size, this is not for the faint of heart. This is the one to circle on the calendar.
The morning of Wednesday the 9th is another one that looks good. The swell has backed off a little, down to 6.9ft, but the wind is light from the south, making for some glassy, clean conditions. The energy is still solid at (2422). It won’t have the size of Monday, but it might be a bit more user-friendly for the advanced crew. The way that SW swell wraps in here, it’ll be a fun one.
Then on Thursday the 10th, we get our first true offshore wind of the whole run. The ESE breeze is light, and the swell is still a healthy 7.2ft from the WSW. This could be the most perfect, cleanest session of the whole period, even if it's not the biggest. The water temp is sitting at a normal 72° for the time of year, so no surprises there.
For the second week, things get a bit more inconsistent and the forecasts are less locked in. There’s still plenty of swell around, but the windows of clean wind get narrower. Mornings look better, afternoons are mostly a bit of a mess. The standout from that period is the morning of Sunday the 13th, which shows 7.9ft from the WSW with a clean cross-off breeze, but it’s a long way out and things could change.
Overall, it’s not a classic run of surf, but it’s far from flat. To be honest, the first week is mostly about being in the water when you can, not when it’s perfect. But that Monday the 7th really does look like the pick of the bunch. It’s got the size, the period, and the wind. Mark it down.

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.
