Table - best surf conditions forecast for Turtles over the next 16 days.
Alright, let’s talk Turtles. This is the only break in the game, and it’s a proper reef for the advanced crew. The next 16 days have a solid run of swell, but not all of it is clean. The best window is the first half of next week, with a tricky middle stretch where the wind gets messy.
The water’s at 74°, which is right on average for this time of year, no surprises.
Monday morning, July 13th, is your best early bet. We’ve got a 7ft SW groundswell, long 18-second period, and light easterly offshore breeze. That’s clean, powerful, and the combined energy is a strong 2706. Turtles will be firing, but it’s an advanced wave, so respect the reef. The wind holds through the morning, but by afternoon it swings SW and goes cross-on, turning it choppy.
Tuesday morning the 14th is also clean with a 6ft SW swell at 16 seconds, a light NE cross-off breeze, and 1816 energy. Another good session. The pattern holds Wednesday morning the 15th, with a 6ft WSW swell, 14-second period, and clean conditions. The wind is light and cross-off, so shape should be good.
Then the wind starts to get moderate from Thursday the 16th through Saturday the 20th. The mornings stay clean with cross-off breezes, but the swell drops a bit in size and the afternoons get choppy. The Saturday afternoon the 18th sees an 8ft WSW swell, but the wind is cross, creating a slight chop. Not ideal.
Sunday the 19th morning has an 8ft SW groundswell, 16-second period, and a clean cross-off breeze. That’s big, powerful, and the energy is 3287 – very strong. This is a proper expert-only session. The wind builds in the afternoon though, making it lumpy.
From Monday the 20th afternoon through to Thursday the 24th, the wind is mostly moderate to fresh, and the surf quality drops. The mornings are often clean, but the swell is smaller, around 4ft to 4ft, and the energy is weak. Thursday the 23rd morning has a 7ft WSW swell, 17-second period, and 2374 energy, but the wind is cross, so it’s not as clean as it could be. The afternoons are choppy.
Friday the 24th morning is worth a mention: 6ft WSW swell, 15-second period, clean cross-off breeze, and 1613 energy. That’s a solid session, but the wind really picks up in the afternoon.
The last few days, Saturday the 25th and Sunday the 26th, are small and wind-affected. Sunday morning the 26th has a tiny 2ft WSW groundswell, but a 21-second period and a fresh offshore easterly. That’s a weird combo – long period, tiny swell, clean but not much power.
Monday the 27th morning looks like another standout: 5ft WSW groundswell, 17-second period, moderate offshore east-northeast wind, and 1422 energy. Clean and punchy. Then Tuesday the 28th morning has a 4ft WSW swell, 15-second period, fresh offshore east wind, and 1437 energy. The afternoon session on the 28th is also solid: 5ft WSW, 16-second period, moderate offshore, and 1766 energy. That’ll be a clean, rippable end to the run.
So, the true standouts are Monday morning the 13th, and Monday morning the 27th. Both are clean, solid size, long period, and strong energy. The rest of the period is a mix of clean mornings and choppy afternoons, with a few smaller days in the middle.
Turtles is a reef, so it’s not for the faint-hearted. If you’re not an advanced surfer, give it a miss. Crowds are often there, so get in early.

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.
