The Lowdown
Alright, let’s get into it. The only game in town for the next 16 days is Turtles, a heavy, advanced reef break. This is a spot that knows how to light up, but it’s not for the faint of heart. We’ve got a solid run of SSW to WSW groundswells rolling in, with periods that are often well over 11 seconds, and some hitting 16 to 20 seconds. That’s proper long-period energy, the kind that makes the reef pulse. But with that kind of power, and a break that’s exposed and rated for experts, you’ve got to be on your game. The water temp is about what you’d expect for this time of year, nothing out of the ordinary.
The first real window of opportunity is Tuesday morning, September 1st. We’ve got a 6 ft swell from the WSW, with a 16-second period, and the wind is SSE cross-off, giving us a clean face. The combined energy is strong (1694), and it’s shaping up as excellent conditions for experienced surfers. That’s the standout for the first week.
We’ve got a rough patch in between. Wednesday, September 2nd, the wind gets up to 19 mph and the swell drops to 5 ft, then Thursday is a write-off with onshore winds. Friday, September 4th, morning looks clean again with a 6 ft SW swell (1346 combined energy), but the consistency is a bit suspect.
Now, hold on to your leash, because the real standout is shaping up for Tuesday, September 8th. The morning is where it’s at: a 10 ft WSW swell, with a massive 20-second period, and the wind is from the east at 16 mph, pure offshore. That’s about as clean as it gets for a reef. The combined energy is pumping at 6501. This is an exceptional window for expert surfers only. That’s your best bet of the whole run.
The following days hold size, but the winds get messy. Saturday, September 12th, we’re looking at an 12 ft WSW swell (5970 combined energy), but the wind is cross-shore, so it’s going to be a lumpy, challenging lineup. Still, the power is undeniable.
The gap between the first week and the second week isn’t huge, but there are a few days in between where the wind and tide aren’t playing nice. The 8th is the clear peak. After that, Monday, September 14th, still has a solid 10 ft SW swell (4392 combined energy) with a clean cross-off wind, but the swell is a bit shorter period at 16 seconds.
In short, for the expert crew, the mornings of September 1st and especially September 8th are the calls. The 8th is the big one. Everything else is a gamble with the wind.

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.
