The Lowdown
Alright, let’s run it down. It’s a one-break show for the full 16 days, so here’s the story.
Turtles is a reef break for advanced surfers only – not a place for learners. Water temp is about normal for the season.
The first week starts rough. Wednesday the 2nd through the early days have swell, but the wind ruins it. A solid SW groundswell with periods from 13 to 14 seconds hits, but the wind is cross, cross-off with too much punch, or cross-on and lumpy. Wave energy runs moderate to strong (1085 to 2066) but the quality is poor. Thursday afternoon on the 3rd is a mess with a fresh cross-onshore and a lumpy 2.1m.
Friday morning the 4th gives the first decent look – clean, gentle breeze, 1.9m SW at 14 seconds. It’s still only marginal, but it’s the cleanest of that early stretch. The weekend is blown out with strong onshore winds and chop.
The real standout window opens Monday the 7th. Morning brings a 2.5m SW groundswell with a long 17-second period and energy at 4425. The wind is fresh offshore from the ESE, so the face will be clean. This is heavy, powerful stuff for pros only. With that long period, expect longer waits between sets but well-shaped waves on the reef. Tuesday the 8th and Wednesday the 9th are still clean but the swell drops a bit.
Best of the whole forecast? Thursday morning the 10th. Glassy conditions, a light 1.8m WSW swell at 14 seconds, and zero wind. The energy is moderate at 1339 but with glass, it’s the cleanest session of the run. Still an advanced wave.
Second week drops off. Friday the 11th turns messy. Saturday the 12th has a strong 2.2m SW groundswell (17 seconds, energy 2904) with cross-off wind, so it could be fun for the skilled, but it’s not as clean. Sunday the 13th is light cross-on and not good. Monday morning the 14th is another good one – offshore ENE breeze, 2.1m WSW swell at 16 seconds, energy 2102. Clean and punchy for experts. The rest of the week fades into onshore wind and smaller, messier surf. Wednesday the 16th has a very long 19-second swell but onshore wind and only 1.2m, so not worth much.
Bottom line: Thursday the 10th morning is the gem. Monday the 14th morning is the solid backup. This spot draws a crowd, so plan accordingly.

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.
