The Lowdown
Alright, folks, Rusty here. Let’s break down the next couple of weeks. We’ve got one main spot on the radar, and it’s got some serious potential, but you’re gonna have to pick your moments.
The standout for the whole period is Turtles (Turtles-2). It’s an exposed reef, fairly consistent, and needs that good SW swell direction to line up. Water temp is sitting at 74°F, which is a solid notch warmer than usual for this time of year, so you might get away with a thinner suit.
The opening days are a bit of a tease. Wednesday afternoon kicks things off with a clean 7ft WSW swell, but the 16-second period and that light cross-off wind will have it looking pretty, but maybe not firing. Thursday morning sees it nudge up to 8ft, clean again, but there’s a note about questionable tides that makes it a bit of a gamble. The wind swings around and gets messier through Thursday and Friday, so those afternoons are gonna be a write-off with a cross-chop.
Saturday is a full loss. The wind is fresh and onshore, the swell drops a touch, and it’s just lumpy. Clean it out of your mind.
Now, hold onto your board shorts, because Sunday the 9th is where it starts to get interesting. We jump to an 12ft WSW swell with an 18-second period. That’s some proper groundswell energy, with the combined energy reading a hefty 6663. The wind is a cross-off, and it’s clean. This is a big, powerful wave; if you’re not an expert, this one’s for watching. The period is long, which can make a reef like this absolutely sing. This is the first true standout – a real pulse of ocean.
Monday the 10th backs off a touch to 8ft, still clean in the morning with a light cross-off, but the wind picks up in the afternoon and kills it.
Then we get a bit of a lull, with average conditions and some stronger winds through the middle of the week. Tuesday the 11th afternoon picks back up to an 12ft SW, and it’s clean, but the wind is up there. It’s not as magic as Sunday.
The standout comes back with a vengeance on the 14th of August. Friday morning brings a clean 8ft WSW with an 18-second period and a moderate offshore wind. Conditions are noted as excellent for experienced surfers. That’s gonna be a stellar session. After that, the 15th and 16th turn poor with onshore winds and a dropping swell.
But then, brace yourselves. The 17th and 18th are looking like something else entirely. There’s a big, solid 12ft WSW swell forecast with a 17-second period. The morning of the 18th shows 6 mph offshore wind and conditions described as "exceptional" for experts. The energy readings for both those days are huge, in the 6500-6900 range. This is the biggest, most promising swell of the whole window, but it’s about ten days out, so treat it as a promising bet rather than a dead cert. This is a high-performance, expert-only wave.
The last couple of days fade out with average condition, more wind, and the swell dropping back to a 7ft.
So, bottom line: if you’re a confident surfer, the real dates to circle are Sunday the 9th and Friday the 14th. The big one on the 18th could be the pick of the bunch, but it’s a long way off. Crowds at Turtles are often a factor, so get there early for those clean morning windows.
This is Rusty, signing off. Keep an eye on the horizon.

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.
