The Lowdown
G’day, Rusty here. Let’s get into it for Turtles, a solid advanced reef break that’s pretty exposed to the southwest swell. Right now, the water temp is sitting about average for this time of year – nothing out of the ordinary.
The window kicks off on Saturday the 18th, but honestly, don’t get too excited. The morning has a 6ft WSW swell with a 14-second period, but the wind is a cross-shore from the NNW. The combined energy is strong (1125), but it’s a bit messy with slight cross-chop. The afternoon drops to a 7ft swell, but the wind turns cross-on from the NW, making it choppy. Neither is worth paddling out for.
Now, Sunday the 19th morning is the real standout. The swell jumps to 8ft from the WSW with a long 15-second period, giving it heaps of grunt. The combined energy is through the roof (3037). And the wind? Offshore from the east at 12 mph. That’s clean, powerful surf for experienced surfers. This is the best on offer – a proper session if you’re up for it. The afternoon fades with a cross-shore wind, so don’t bother.
Monday the 20th and Tuesday the 21st are a write-off. The swell drops to 4ft-6ft, and while the wind is cross-off, the energy is moderate (756-1172). The surf is marginal, and the conditions aren’t there. Wednesday the 22nd is similar – 5ft-5ft SW swell, clean but weak.
Thursday the 23rd morning has a tiny 3ft WSW swell, but the offshore wind from the east at 19 mph makes it look clean. Still, it’s too small to get excited about. Friday the 24th afternoon is a nice surprise – glassy conditions with the wind from the ESE at just 3 mph, and a 4ft SW swell. The energy is moderate (543), but the glassy surface means it’ll be fun and clean. A good little session.
Saturday the 25th is a dud – onshore winds in the afternoon kill it. Sunday the 26th morning has a tiny 2ft WSW swell, but the period is a massive 21 seconds, and the offshore wind from the ESE makes it look clean. The energy is moderate (765), but it’s a long-period groundswell, so it’ll be super straight at the break. Only worth it if you’re patient.
Monday the 27th morning is another standout. The swell is 5ft from the WSW with a 17-second period, and the wind is offshore from the east at 9 mph. The combined energy is strong (1560), and the conditions are clean. This is great for experienced surfers. Tuesday the 28th morning is glassy with a 5ft SW swell – perfect for a clean, easy paddle out. Wednesday the 29th morning is also clean with a 4ft SW swell, but it’s small.
Thursday the 30th morning has a 8ft WSW swell with a 16-second period, but the wind is cross-off from the SSE at 16 mph. The energy is very strong (2697), but it’s clean. This is big and powerful, only for experts. The afternoon gets choppy with a fresh cross-shore wind.
Looking into the second week, Friday the 31st morning has a fresh offshore wind from the ESE at 19 mph with a 6ft WSW swell (14 sec). The energy is strong (1541), and it’s clean. A solid option for experienced surfers. Saturday the 1st of August morning has a 6ft WSW swell with a 17-second period and a fresh offshore wind from the ENE at 19 mph. The energy is very strong (2267). The afternoon is even better – glassy offshore from the east at 6 mph with a 6ft swell. This is excellent for those who know what they’re doing. Sunday the 2nd of August morning fades to a 5ft swell with moderate energy.
Overall, your best bets are the morning of Sunday the 19th and Monday the 27th. Those are the standouts. The rest is a mix of clean but small, or big and clean but only for the brave. Crowds can be an issue at Turtles, so keep that in mind for the good sessions.
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.
