The Lowdown
Alright, let’s get into it. This is Rusty, and I’m looking at what’s on the cards for Turtles over the next couple of weeks.
First off, we’ve got a bit of a slow start. Saturday the 18th is nothing to write home about – it’s cross-shore and choppy, and the swell’s not organised. You’d be better off waiting.
The real action kicks off Sunday the 19th morning. That’s the standout for the whole run. We’ve got a solid 8 ft swell rolling in from the WSW, with a 15-second period – that’s proper groundswell, long and powerful. Water temp is sitting at 74°, which is pretty average for this time of year, no big anomaly there. But the big news is the wind: clean easterly offshore at 9 mph. That’s going to put a glassy lip on the reef. This is advanced territory at that size though – 8 ft is for experienced surfers only. If you’ve got the skills, Sunday morning is the standout.
After that, swell backs off through Monday and Tuesday. We’re looking at 5 ft to 4 ft, but the wind starts to mess things up. Monday afternoon gets messy, and Tuesday sees some cleaner conditions but the size drops.
Wednesday the 22nd has a small window with offshore winds in the morning, but it’s only 4 ft. It’s clean, but not pumping.
Thursday the 23rd is worth a mention. Morning has a 5 ft SW groundswell with a 16-second period, and offshore ENE wind at 19 mph. That’s a solid combo for the reef – long-period groundswell like that really lines up nicely at a place like Turtles. The combined energy reading is strong at 1265, so there’s plenty of push. Thursday afternoon cleans up even more with moderate offshore wind.
Friday the 24th stays clean in the morning with offshore wind and 4 ft swell, but the afternoon turns to rubbish with onshore wind.
Saturday the 25th is another clean morning with 4 ft swell, but it’s small. Best for a longboard or a mellow session.
Now, here’s the next real standout: Monday the 27th. Morning session sees a solid 6 ft WSW groundswell with a 16-second period, combined energy hitting 1904, and moderate offshore wind from the east. That’s a powerful, clean setup. Again, that’s expert territory when it’s over 5 ft, but the quality is there.
After that, the swell drops again. We get a bit of a bump on Thursday the 30th morning – 7 ft from the WSW at 18 seconds, combined energy at 2640, but it’s cross-offshore and the wind is moderate. It’s clean, but not as perfect as the earlier windows.
The first week of August sees smaller swell, mostly under 5 ft, and cross-shore or onshore winds messing up the afternoons. Mornings stay cleaner but the size is modest.
All up, the standout is Sunday the 19th morning – best quality, biggest swell, and perfect offshore wind. The second highlight is Monday the 27th morning, for another dose of solid groundswell with clean conditions.
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.
