The Lowdown
Alright folks, Rusty here. Let’s break down what’s on the table for Turtles. This is a proper reef setup, but it’s for advanced surfers only, and it’s fairly consistent – so when it’s good, it’s really good. We’ve got a solid run of southwest groundswell lining up, with a few absolute gems if you pick your windows.
The week kicks off on Tuesday, August 25th. The morning is the play, with a clean 5 ft SW swell at 13 seconds. The wind is a light cross-offshore from the SE at 9 mph, and the water is about average for the time of year. The combined energy is moderate (766). It’s a good start, but the afternoon gets messy with a strong SW cross-on wind, so morning is your only window.
Wednesday, August 26th, is where it gets interesting. The morning is a standout. We’re looking at 5 ft of SW swell, but the period jumps to 14 seconds, and the wind goes glassy – absolute stillness from the NNW at 3 mph. The energy is building into a strong category (1124). This is clean, powerful, and perfect for experienced surfers. The afternoon, however, turns into a 7 ft onshore mess with a W wind, so get out early.
Thursday, August 27th, is only for the experts. The morning has a solid 10 ft WSW swell, but it’s a long-period groundswell at 16 seconds. The wind is a strong cross-off from the SSE at 19 mph, keeping it clean, but the energy is very strong (4533). This is heavy, straight-breaking reef stuff. If you’re not dialed in, stay on the beach. Friday and Saturday morning (28th and 29th) are similar but smaller, with clean 8 ft and 5 ft swells, but the wind is up from the SE, making it punchy.
Now, the next true standout window is Sunday, August 30th. The morning is a beauty: 7 ft of WSW swell with a very long period of 19 seconds. The wind is a gentle offshore from the ESE at 9 mph, and the energy is strong (2938). This is a proper groundswell, so expect long, clean lines at the reef. The afternoon, again, gets ruined by a cross-on wind.
Monday, August 31st, is another strong morning option. Same 7 ft WSW swell, 16-second period, with a light offshore breeze from the SE. Clean, powerful, and good for experienced surfers. The energy is strong (1948). The pattern is clear: mornings are gold, afternoons are trash.
There is a gap of a few days after Tuesday, September 1st, where the wind gets messy and the swell drops, but the run continues into the second week. Saturday, September 5th, sees a return of clean 7 ft SW swell in the afternoon, and Sunday, September 6th, has a clean morning with 5 ft SW swell and a light NE wind. That’s a solid, consistent option.
The last big call is Monday, September 7th. The morning has a massive 8 ft WSW groundswell, with a very long period of 20 seconds. The energy is extremely strong (5529). This is proper big-wave territory. The wind is a cross-shore from the S, so it’s lumpy, but the power is undeniable. Only for the experts. The next morning, Tuesday, September 8th, and Wednesday, September 9th, both offer clean 7 ft and 5 ft swells with offshore winds, rounding out the run.
The absolute best on offer? Wednesday, August 26th morning, with 5 ft of glassy, 14-second groundswell at Turtles. For a bigger, more powerful session, Sunday, August 30th morning with that 19-second, 7 ft groundswell is a close second. Get on it.
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.
