Table - best surf conditions forecast for Turtles over the next 16 days.
Alright folks, Rusty here. Let’s talk about what’s coming up for Turtles. This is a solid, advanced reef setup that’s fairly consistent, so we’ve got a bit of a run ahead. The water is sitting at 74.1°, which is pretty much normal for this time of year, so no surprise there.
The real action starts Sunday morning, July 12th. We’ve got a clean 5 ft swell from the SW, with a light cross-off breeze from the ESE. The energy is moderate (946), and while the waves are a bit on the smaller side, the conditions are clean. It’s a marginal call, but it’s a start.
The standout window is Monday morning, July 13th. This is the pick of the first week. The swell jumps to 6.6 ft from the WSW, with a period of 18 seconds – that’s proper groundswell, giving those waves some serious shape and power. The energy is strong (2568), and with a light cross-off breeze from the ESE, it’s going to be clean. This is excellent surf for experienced surfers, but at 6.6 ft, it’s getting into the big stuff, so leave the beginners on the beach. Expect crowds to be likely, as this spot gets busy when it’s good.
Tuesday morning, July 14th, keeps the run going with a 6.2 ft SW swell, still very clean with a light cross-off breeze. The energy is still strong (1816), and the conditions are excellent for experienced surfers. Wednesday and Thursday mornings offer similar, but slightly smaller, clean 5.2-5.6 ft swells, though the energy drops a bit. The crowds will still be around.
We hit a bit of a lull through the afternoons with choppy, cross-onshore winds, but the mornings stay clean. Saturday morning, July 18th, brings a punchy 5 ft swell from the WSW, but the real story is the energy jumping to 1574 with a clean cross-off breeze. It’s another excellent session for the experienced crew.
Now, Sunday morning, July 19th, is the big one. We’re looking at an 8.2 ft swell from the WSW with a 16-second period. The energy is very strong (3738), and the wind is a clean cross-off. This is heavy, powerful surf. It’s only for experts. The crowds will be there, but it’s going to be a battle.
After that, the second week looks more inconsistent. The swell drops, and the wind turns messy. Tuesday morning, July 22nd, is a little interesting – it’s glassy, with a 5 ft SW swell, but the energy is low (744). It’s a small, clean window, but not a standout. From Wednesday, July 23rd, into the weekend, the wind picks up to a fresh breeze, and the swell gets bigger again, hitting 9.8 ft on Friday morning, July 24th, but with strong cross-off winds. The energy is very strong (4674), but these are tricky, marginal conditions. The last few days of the forecast drop off steadily, with the swell fading and the wind becoming a problem.
Overall, the best sessions are the Monday and Tuesday mornings of the first week, and the big Sunday morning on the 19th. That’s where the real quality is. After that, it’s a waiting game.
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.
