The Lowdown
Alright, I'm Rusty, and we're looking at the same stretch of water, just in feet and miles per hour.
We've only got one spot that's really in the game for the next 16 days: Turtles. It's a heavy, advanced reef break that needs a solid SSW swell to get good, and it's about as reliable as they come here. But it's not all clear skies—there's a rough start, with some real slop for the first few days.
The water's sitting around 74°, which is a touch warmer than usual for this time of year. Nothing wild, just a bit warm.
Starting Saturday the 8th, it's ugly. A solid 7ft swell from the WSW, 15-second period, but a strong 25 mph cross-onshore wind is just wrecking it. The energy is high (2344), but the surface is a total mess. Don't bother. The afternoon is the same story with a 7ft swell.
Sunday the 9th is a big change. Morning looks clean with a 10ft SW groundswell, a long 17-second period, and a light cross-offshore breeze from the SE at 18 mph. The energy is huge (5977), but the tide is a bit off. It's rideable for the experienced, but not perfect. The afternoon cleans up more with lighter winds, same size swell. This is the first real window.
Monday the 10th morning is the pick of the first week. A 8ft SW swell, 15-second period, with a light 6 mph cross-offshore breeze. The water is clean, energy is still strong (3045), and it's excellent for experienced surfers. The wind is light, so it'll be smooth. The afternoon is a total loss—wind turns onshore and chops it up.
Tuesday the 11th and Wednesday the 12th mornings are both clean, but the wind is fresh to strong (22-25 mph) from the SE, holding it together but making it a workout. The swell stays solid at 8-10ft, long period, and the energy is up there. It's a grind, but it's there.
Thursday the 13th morning is a real beauty. 6ft of SW groundswell, 15-second period, and a clean offshore easterly breeze at 15 mph. The waves will be clean and lined up, with moderate energy (1676). This is a good call.
Friday the 14th morning is similar—7ft, 16-second period, gentle cross-offshore breeze, clean. Solid. The afternoon gets trashed by onshore wind again.
Saturday the 15th morning is another clean offshore morning, 6ft, 15-second period, gentle breeze. Nice. Afternoon, back to chop.
Sunday the 16th is smaller and onshore, not much to say. The energy drops to 690.
Now, here's the long-range look. Monday the 17th morning, we have a glassy, 5ft WSW swell with a very long 19-second period. The energy jumps to 3529. The wind is almost nothing, just a slight air, and the surface is glassy. This is a proper, clean, long-period groundswell. For a reef like Turtles, this could be a standout. It's over a week away, so keep it in mind, but it looks promising.
Tuesday the 18th is a bit more wind-affected, but still a solid 8ft swell.
Then, Wednesday the 19th morning is a monster. 13ft of WSW swell, 16-second period, with a moderate cross-offshore breeze and clean conditions. The energy is a massive 7522. This is big, heavy, and for experts only. The afternoon gets a strong cross-onshore wind, so it's a morning-only mission.
The rest of the run into the 23rd has some clean mornings and some choppy afternoons, with the swell staying in the 7ft to 10ft range. The 23rd morning has a clean 10ft, 16-second swell with a moderate cross-offshore breeze—worth a look.
Overall, if you're an experienced surfer, the best bets are Monday the 10th morning, Thursday the 13th morning, and the glassy Monday the 17th morning. The 19th morning is a big-wave day for the brave. The afternoons are mostly junk, so plan your dawn patrols.
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.
