The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming our way.
Alright, we’ve got a real mixed bag on our hands. The first few days are a bit of a write-off with average conditions, but if you’ve got patience, the end of this stretch is where the magic is hiding. The water temp is sitting at 71°, which is about normal for this time of year, nothing wild there.
The window starts on Tuesday the 8th. The swell shows up at Turtles (reef) with a 7 ft from the WSW, but that south-southeast wind at 30 km/h is making things messy. You can forget about Tuesday afternoon.
Wednesday the 9th morning is a bit of a tease. The swell bumps up to 7 ft from the SW, and you get a proper offshore from the ESE at 30 km/h, so it *looks* clean on paper. But the energy reading of 2173 is just moderate, and it’s still a bit lumpy with a marginal feel. Not a standout.
Thursday the 10th morning is the first real glimmer. You’ve got a 6 ft WSW swell with an easterly light breeze, 10 km/h offshore. That’ll be clean and the energy is 1399 (moderate). Best bet of the first week for sure, but you’ll want to be experienced with these conditions.
Friday the 11th and the weekend are a bit of a letdown as the swell drops and winds turn onshore. Sunday the 13th is a washout with fresh cross-shore winds.
Now, hold onto your board for Saturday the 12th morning. That’s a grommet’s dream – glassy conditions, winds only 5 km/h from the WNW, and a 7 ft WSW groundswell with a very long period of 17 seconds. The combined energy is strong at 2605. This is a classic combo of power and glass. The only catch? This is a reef break, so that long period will make it suck out a bit, but for the experienced surfer, this is a ripper.
There’s a long gap of choppy, poor surf from the 12th afternoon all the way through to the 19th. Mostly onshore wind and messy conditions. Not worth paddling out.
The big one is on Monday the 21st of September. Get this: a 10 ft SW groundswell with an 18-second period. That’s a massive amount of energy (6298). The wind is offshore out of the east at 15 km/h, making it glassy and clean. This is the heavyweight champion of the forecast. Only for experts at that size, but the conditions are as good as it gets. If you can handle it, this is the day.
Tuesday the 22nd drops off a bit, but Wednesday the 23rd morning offers another good window: an 8 ft SW swell, clean with a light south-southeast cross-offshore breeze. Experienced surfers will have a great session.
So, for the standouts: Thursday the 10th morning is the early pick for some clean, medium-sized waves. But the real, no-doubt-about-it session is Monday the 21st of September morning. It’s a monster, it’s clean, it’s powerful. Circle that date.
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.
