The Lowdown
Alright folks, Rusty here. Let’s get into it for this stretch of the coast. We’ve got one spot on the radar, and it’s a proper reef slab that needs a keen eye and a steady nerve.
The first real chance to get wet will be on Monday, 1st September. The morning is where it’s at. We’re looking at a solid 6 ft of swell running from the WSW, and the wind is a light cross-offshore breeze from the SSE. That’s going to clean things up nicely, giving you some tidy, lined-up waves. This is advanced territory, so only head out if you know what you’re doing. The combined swell energy is sitting at 1692, which is plenty of grunt. The water temp is 72°F with a slight anomaly of 0.9°F, so it’s pretty standard for the time of year. The period is a long 16 seconds, which is proper groundswell – it’ll wrap around the reef and offer some proper shape, but those waves will be packing a punch.
Monday afternoon starts to deteriorate with a stronger cross-on breeze, so the morning is the clear winner.
Tuesday, 2nd September morning is a bit smaller at 5 ft and still WSW, but again that cross-off wind from the SSE will keep it reasonably clean. The energy is moderate at 1033, and the period has dropped to 14 seconds. It’s a marginal call, but if you’re keen, the windows are there. The afternoon gets blown out with a strong 25 mph cross-shore, so forget it.
We then run into a messy patch with strong winds making things lumpy and choppy for the next few days, especially through the 3rd and 4th of September.
Now, let’s talk about the standout. Saturday, 5th September morning brings a chunky 8 ft swell from the SW with a 16-second period. The energy is cranking at 3178. The wind is a light cross-on, so it’ll be a bit textured, but that is a lot of water moving. This is big for this spot, and with that period, it’ll be a heavy, moving reef wave. This is expert only territory. The afternoon gets hammered by a 25 mph Westerly, so it’s a one-trick pony.
The following week has a massive pulse. Monday, 7th September morning is all about size: 10 ft from the WSW with an 18-second period. The energy is monstrous at 5472. The wind is a clean cross-off from the ESE, meaning it’ll be a beautiful, powerful beast. But be warned, this is a serious, serious ocean. Only for the very experienced. That pattern holds through the morning of Tuesday, 8th September, where we get a proper offshore wind from the E at 19 mph with 7 ft of SW swell. That’s about as clean as it gets for a big session, but the energy is still very high at 3994.
Then, mark your calendar for Thursday, 10th September morning. This is the one. The forecast shows 8 ft of WSW swell with a 16-second period, and the wind is glassy – a 3 mph breeze from the SW. That is a rare, perfect window. The energy is 3444, and the conditions are described as excellent for experienced surfers. This is the best chance of the whole forecast for a truly memorable, clean session on that reef. The size is big, but with no wind, it could be the session of the month.
The following days stay solid with 6 ft+ swell and clean cross-off winds in the mornings, particularly Friday, 11th September and Saturday, 12th September mornings. But the true standout is that glassy Thursday morning.
So, to wrap it up: the best on offer is Thursday, 10th September morning at Turtles for that glassy perfection. The second best is the Monday, 7th September morning for sheer power and clean conditions. Get on it, but respect the reef.
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.
