The Lowdown
Alright, let's talk about Turtles. This is a proper reef break that demands respect – advanced only, and that's not just talk. We've got a long window ahead with plenty of action, but a few sessions that will really make it worth paddling out.
Right out of the gate, Wednesday the 29th morning is looking sweet. We've got a clean 5-foot SW groundswell rolling in with a nice 14-second period, and the wind is a light cross-off breeze from the NE. The water temp is sitting at 73°, which is bang on average for this time of year, so no nasty surprises there. The combined energy is pumping at 1318 (moderate to strong), and it's just excellent for experienced surfers – a classic morning session.
Thursday the 30th morning is still a goer, with 5-foot SW groundswell and a long 16-second period – really nice lines – and a light SSE cross-off keeping things tidy, though the energy drops a notch. The afternoon goes sour with a strong SW cross-onshore wind, so get it early. Friday the 31st is a bit of a gamble; the morning has a clean 4-foot swell but a moderate cross-off, and the afternoon gets messy with stronger winds and lumpy chop. Saturday the 1st and Sunday the 2nd are both tricky, with fresh winds and a building swell around 7 feet, though Sunday morning has a solid 6-foot SW groundswell and a clean cross-off – one to watch but not a standout for me.
The real standout of this whole run? That's gotta be Friday the 7th of August morning. We are looking at a solid 10-foot SW groundswell, period at 16 seconds, and a light cross-off breeze from the S keeping things clean. The energy is enormous at 3784. This is big, powerful, and for experts only – a proper reef grinding session. It's still over a week away, so not locked in, but the potential is massive.
Just behind that, the period around Monday the 10th and Tuesday the 11th of August is pumping with serious size. Monday the 10th afternoon sees 13-foot WSW swell with a 19-second period and strong breeze but cross-off from the SE – huge energy at 10669 (very strong). Tuesday the 11th morning has a clean 12-foot WSW swell with an offshore E wind at 25 km/h and energy at 6517. Both are for the brave only. The crowd profile here shows "often" crowds, and on a spot this good with this kind of swell, expect company.
Keep an eye on Wednesday the 12th morning too – a cleaner, more manageable 7-foot SW groundswell with a moderate offshore E breeze. A solid session for the top crew.
A few things to mind: this is a reef break and with periods over 15 seconds on those big swells, they can barrel hard and shut down fast – not for the faint-hearted. Also, any afternoon with a SW cross-onshore wind (like Wednesday the 5th) will be a write-off.
So, to sum it up: get on the Wednesday the 29th morning for a clean, meaty session. Circle Friday the 7th of August morning in your calendar – that's the one to chase. The big days around the 10th and 11th are for the elite. The rest of the window is a mixed bag of clean mornings and blown-out afternoons, but there's enough to keep a keen surfer ticking over.

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.
