Table - best surf conditions forecast for Turtles over the next 16 days.
Alright, Rusty here. Let’s break it down.
First up, we’ve got a solid run of swell coming through for Turtles. This is an advanced reef break, so it’s not for the faint-hearted. The water temp is sitting at 74°, which is about average for this time of year, so nothing wild there.
The forecast kicks off on Friday the 10th of July, but honestly, that’s a write-off. Cross-onshore wind and choppy conditions with a 5ft swell from the WSW – it’s a messy one. The combined energy is moderate at 685, but the quality just isn’t there.
Saturday the 11th morning is where it starts to get interesting. A clean 4ft SW groundswell with a 13-second period, and light cross-offshore wind from the SE. It’s only small, but the energy is a moderate 428 and the face will be clean. The afternoon turns ugly again with a strong cross-on, so get it early.
Now, Sunday the 12th morning is a real standout. The swell drops a touch but the wind goes full offshore from the ESE, just a gentle breeze. That 5ft SW groundswell (14-second period) is going to be clean and lined up. Combined energy is a healthy 946 (moderate). This is the best call of the first week for me – smooth, offshore, and a solid reef.
Monday the 13th morning brings a bigger pulse: 7ft from the WSW with a long 18-second period. That’s a proper groundswell. The energy jumps to 2471 (strong) and with light offshore wind, it’s going to be powerful. At 7ft, it’s getting into expert territory, especially on a reef. The long period means longer lulls between sets, which helps with the paddle, but the wave itself will be fast and heavy.
Tuesday the 14th morning is glassy. Absolutely glassy. No wind, a 6ft SW swell with a 16-second period. Energy is 1833 (strong). This is exceptional quality for experienced surfers. The reef will handle this long-period swell beautifully, keeping the waves from just closing out.
The pattern holds through the week with clean mornings and messy afternoons. Wednesday the 15th morning is another clean, offshore morning with a 6ft swell. Thursday the 16th and Friday the 17th are similar – clean mornings, but the afternoons get chopped.
Saturday the 18th morning is clean but the wind is strong from the SSE at 16 mph, which is cross-offshore. The swell is 5ft with a 13-second period, but the energy is strong at 1547. It’s surfable, but that wind is fresh. The afternoon is a total mess with a 8ft, 19-second swell and 22 mph cross-shore wind – that’s 5119 energy, but it’s more for kite surfers than paddle surfers.
Sunday the 19th morning is a big one: 10ft from the SW with a 16-second period. Energy is 4396. That’s very strong, and at 10ft, this is strictly for experts only. The wind is cross-offshore, so the waves will be clean, but the size and power are extreme. Afternoon is the same size but with a lumpy cross-shore wind.
The swell drops through the next week. Monday the 20th is still solid at 7ft, but the wind is stronger. By Tuesday the 21st, the swell drops to 4ft and the wind is fresh and howling, making it poor. Wednesday the 22nd and Thursday the 23rd are small and clean but marginal. Friday the 24th morning is a nice little window: 4ft SW swell, 14-second period, light cross-offshore wind, and clean. Energy is 642 (weak to moderate). It’s a smaller day but the quality is there.
The last real standout in the second week is Saturday the 25th morning: 6ft from the WSW, 14-second period, with a clean cross-offshore wind. Energy is 1333 (strong). It’s a solid option for a weekend session, though the wind is a bit stronger.
Overall, the best of the whole 16-day window is Sunday the 12th morning for the offshore glass, and Monday the 13th morning for the raw power. If you’re an expert, the 19th is a monster but clean. Crowds are often a thing at Turtles, so expect company on the standouts.
Stay safe out there.

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.
