The Lowdown
Alright folks, Rusty here. Let's get into it.
Right off the bat, we’ve got a solid, meaty run of SW groundswell heading our way. The energy is kicking in strong, with combined swell energy values consistently in the four-digit range, indicating moderate to strong wave energy. The main event is a classic, exposed reef set-up that’s going to be handling this energy, but the wind is going to be the main character in this story.
The first real opportunity to paddle out is Thursday, September 3rd. Turtles is seeing a 5.6ft SW groundswell with a 13-second period. The water is sitting at 72.1°F, which is about average for this time of year. The snag is a 15 mph S cross-breeze. It’s going to be bumpy and chopped, creating a cross-chop that’s more work than fun. The afternoon looks even worse as the wind swings and strengthens, so Thursday is for the keen only.
Friday the 4th is more of the same story. Swell hangs in at 6.2ft from the SW, period pushing up to 14 seconds. The morning has a 12 mph S cross-breeze, which keeps things lumpy. The afternoon gets hammered by a 19 mph SSW cross-breeze. It’s messy out there.
Now, Saturday, September 5th is a real stand-out for the sheer size, but it comes with a massive caveat. The morning swell jumps to 8.2ft from the SW with a 16-second period. The energy is massive at 3178, but you’ve got a 9 mph cross-onshore wind. At this size, that wind is going to make it unruly and dangerous. This is only for experienced surfers, and even then, the conditions aren't doing it any favors. The afternoon is a no-go with 22 mph cross-onshore winds.
Sunday, September 6th is a day for the brave. The swell hits 11.5ft from the SW in the morning, with a 13-second period and a monster 3520 combined energy. With a 25 mph S cross-offshore wind, the face will be clean, but 11.5ft is heavy-duty stuff. This is strictly for experts only. The afternoon is trashed by a 28 mph S cross-breeze.
After that massive pulse, the energy backs off but stays solid. Monday, September 7th is a beauty if you want a cleaner, more manageable wave. The morning delivers a 5.9ft swell from the WSW with a 17-second period. The wind is a 19 mph SE cross-offshore, and it's described as clean. It’s a great opportunity with good shape. The afternoon holds at 8.2ft with a 16-second period and a clean 19 mph cross-offshore. This is a good day.
Tuesday the 8th and Wednesday the 9th of September keep the quality high. Tuesday has 6.6ft SW swell with 15-16 second periods, and clean 19-22 mph cross-offshore winds. Wednesday the 9th has a morning highlight: a 6.6ft WSW swell, 16-second period, and a 15 mph offshore wind from the ESE. This is going to be clean and hollow. A top pick for the experienced crew.
Honestly, the absolute standout of the whole run looks like Thursday, September 10th. The morning at Turtles is firing. You’ve got a 6.2ft WSW swell, a 15-second period, and a light 6 mph offshore wind from the east. It’s going to be glassy and clean, with that long-period groundswell offering proper, lined-up walls on the reef. This is the session to circle on the calendar. The quality is high for experienced surfers. After that, the afternoon gets blown out, so make it a dawn patrol.
The next few days fade out a bit. Friday the 11th drops to 4.9ft and gets messy. The weekend of the 12th and 13th of September is a write-off with onshore winds and choppy conditions.
However, there’s a late bloomer. Sunday, September 13th sees a new 8.2ft pulse from the WSW with a 15-second period. The morning has a clean 12 mph SSE cross-offshore wind. That’s a promising setup, but it's a week and a half away, so keep an eye on it.
The run ends with a smaller but clean morning on Monday the 14th (7.5ft, clean) and a final, glassy opportunity on Wednesday, September 16th morning, with 4.9ft WSW swell and a 12 mph offshore easterly. It’s a smaller version of that perfect Thursday morning, but still a very solid option.
Overall, the consistent groundswell and a few windows of clean, offshore wind mean there are proper waves to be had. The 10th of September morning is the one to plan for. Be aware that this spot is for advanced surfers, and the crowds are often around.

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.
