The Lowdown
G'day, it's Rusty. We've got a bit of a mixed bag coming up for Turtles over the next couple of weeks. No real stunners in the first week, but there's a solid window of opportunity that's worth keeping an eye on. The overall pattern is one of building swell, but we'll have to deal with some tricky winds along the way.
Right now, things are pretty average. Friday the 11th is a no-go, with a marginal 4ft swell from the WSW and a light onshore breeze making it messy. Saturday morning the 12th is where it starts to get interesting. The swell jumps to a solid 7ft from the WSW, with a very long period of 17 seconds. That's a proper groundswell. The wind goes glassy, so the face will be clean. The combined energy is pumping at 2605 (moderate to strong), so there's plenty of push. That's a lot of power, over 8ft, so this one is strictly for the experts. It's a reef break, which is good for that long-period stuff, but it's exposed and the crowds are often there. Saturday arvo though, the wind swings to a cross-on 16 mph and kills it.
Sunday morning the 13th is a bit smaller at 6ft, but with a cross-shore breeze it's a fallback option, scoring a 3 in the books. The real standout, though, is looking like Saturday the 19th. That's a week and a day away. Early morning, the swell is a solid 8ft from the WSW, with a long period of 16 seconds. The wind is a cross-offshore 12 mph, which is a rare treat for this spot, making it look clean. The combined energy is a massive 3369 (strong). That's a big, powerful swell. It's going to be a heavy one for experienced surfers only. The crowds are likely to be there for that one.
The second week gets a bit more mixed. The swell of 10ft on Tuesday the 22nd is big, but the wind is a cross-on 12 mph, so it's not as clean. The energy is huge at 3713, but the conditions are just marginal. Overall, the best window is that Saturday morning the 19th, with Saturday morning the 12th as a close second, but only for the hardcore crew.
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.
