The Lowdown
Alright, let’s talk Turtles. This is the only break in the mix, a solid advanced reef that’s fairly consistent. Water temp is about average for the time of year. Nothing unusual.
The first real surf worth paddling for is on the morning of Saturday, August 29th. Swell is 5ft from the SW with a 12-second period, and the combined energy is moderate (842). The wind is light cross-off from the SSE, so it’s clean. Not a heater, but a decent start.
Then, Sunday, August 30th morning is the standout. Swell is 6ft from the WSW with a very long 17-second period – that’s real groundswell. The energy is strong (2113). The wind is glassy, dead calm from the WNW, so it’ll be perfect. This is the best of the run. For experienced surfers only, as it’s an advanced reef. The afternoon gets a light onshore, so get in early.
Monday, August 31st morning has 7ft from the WSW at 16 seconds, but the wind is a light cross-on from the WSW, so it’s a bit blown. The energy is still strong (2345). A step down from Sunday.
The first week of September is a slow decline. Tuesday the 1st, Wednesday the 2nd, and Thursday the 3rd all have decent sized swell, around 5ft to 6ft, but the wind is cross-off or cross, and the conditions are just “clean” but not special. The energy is moderate to strong. Nothing to write home about.
Friday, September 4th is a total washout with strong cross-onshore winds and lumpy conditions. Swell is 7ft from the SW, but it’s messy.
Saturday, September 5th morning is back to clean cross-off winds with 6ft from the WSW, but again, it’s not a standout.
Now, Sunday, September 6th morning is the second big standout. The swell is 8ft from the SW with a 15-second period, and the energy is very strong (3093). The wind is offshore from the ENE, light breeze, so it’ll be clean. This is big, solid swell – experts only, as it’s over 8ft. The afternoon turns onshore and choppy, so it’s a morning-only deal.
Monday the 7th and Tuesday the 8th of September see the swell staying big at 7ft to 8ft, but the wind is cross-on or cross, making it lumpy and choppy. The energy stays very strong. Not the best conditions for the size.
Wednesday, September 9th morning is cleaner with cross-off winds and 8ft from the SW, but it’s still a big, powerful groundswell. The afternoon is a write-off.
Thursday the 10th and Friday the 11th of September see the swell dropping to 6ft to 7ft, but the wind is cross-on and onshore, so the quality is poor. The run fizzles out.
The absolute best windows are the morning of Sunday, August 30th with glassy conditions and long-period groundswell, and the morning of Sunday, September 6th with big, clean offshore swell. Both are for experts only. The rest of the period is a mix of clean but not amazing, or messy onshore conditions.

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.
