The Lowdown
Alright, surfers, this is Rusty. Let's talk about the next couple of weeks. Water temp is a typical 73°F, nothing unusual.
All the action is at Turtles (reef). We've got a solid run of groundswell, but the wind is going to be a factor.
Sunday the 23rd kicks off with a bumpy 6ft SSW swell. The wind is cross and messy, so not a great start. The wave energy is strong.
Monday the 24th is a better bet. The morning session is the pick with a clean 6ft WSW swell and a good cross-off breeze. The swell period is a solid 15 seconds, so plenty of energy. The afternoon gets messy, so get out early.
Tuesday the 25th is similar. Clean morning with a 5ft SW swell, but energy is dropping. Afternoon is a no-go.
Wednesday the 26th sees a big pulse. The afternoon brings a massive 8ft swell from the WSW with a very long 19-second period. The energy is huge, but it's blowing straight onshore. That's big, powerful, and messy.
Thursday the 27th is a big day. The morning has a clean 10ft SW swell with a 16-second period. The energy is massive. This is for experts only. The afternoon is howling with a 25 mph crosswind, making it a total mess. Friday the 28th cleans up a bit with a 7ft SW swell, but the wind is strong.
Here's the standout. Look at Saturday the 30th of August. The morning session is where it's at. A clean 6ft WSW swell with a 17-second period, and a solid offshore breeze from the east. The energy is pumping. That's the kind of window you plan for. The afternoon turns onshore, so it's a morning mission.
Then Monday the 31st is another cracker. The morning has a clean 6ft WSW swell, a 16-second period, and a light offshore breeze. The sets will be clean and powerful. This is a top-notch session for experienced surfers.
The first week of September sees the swell hold steady around 6ft to 6ft from the WSW, but winds are a bit more unreliable. The mornings are the play. The real highlight is Saturday the 5th of September. The morning session is clean, with a 6ft SW swell and a light offshore breeze. That one's a keeper.
The second week sees the swell taper off, but still with some decent pulses. The 7th of September brings an 8ft SW swell, but the wind is onshore and choppy, so it's a big, messy one.
Overall, the best windows are the mornings of the 30th and 31st of August, and the morning of the 5th of September. Get on them.
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.
