The Lowdown
Alright, Rusty here, let's talk about what's coming up for Turtles.
Alright, listen up, the next couple of weeks at Turtles are looking like a mixed bag of serious potential and some real frustrating days. We've got a lot of swell energy on the charts, but the wind is going to be the main character here, often making things a mess. The water temp is sitting right around 72°, which is about average for this time of year, so no complaints there.
The first real chance to get wet is Saturday morning, September 5th. We're looking at a solid 8ft of SW swell, with a 16-second period pushing a massive 3178 (moderate energy) into the reef. But here's the rub – the wind is cross-on from the SW at 9 mph, making it a bit choppy. It's a bit of a frustrating start, 'cause the power is there but the conditions are messy.
Sunday the 6th is a write-off. The wind is howling from the south at 28 mph, making a total mess of the 12ft SW swell. That's just dangerous and ugly, not fun.
Monday the 7th is a bit of a tease. The wind shifts to a cross-off from the SE at 22 mph, which will clean it up, but the swell is still a hefty 10ft. The energy is sky-high at 4856 (strong energy), but that's a big, powerful wave for a reef. For the experienced crew, the morning session could be absolutely pumping, but you'll need your wits about you.
The standout period, without a doubt, is the morning of Thursday, September 10th. The wind goes light and offshore from the east at just 6 mph, leaving the 6ft WSW swell glassy and clean. The energy is a solid 1540 (moderate energy), and with a 15-second period, those waves will have real shape and power. For an advanced surfer, this is the pick of the bunch. The afternoon is a write-off as the wind swings onshore, so get it while you can.
The following week is a real mixed bag of small windows. Sunday morning, September 13th, has a beautiful 5ft WSW swell with a clean cross-off breeze from the SSE at 9 mph. The energy is moderate at 1094, and it's a much more manageable size. Then Tuesday morning, September 15th, is another good call with a 7ft WSW swell and a clean cross-off wind from the SE at 9 mph, energy at 2337 (moderate energy). Both of these mornings are for the more experienced surfers, as the reef can be tricky.
Beyond that, the pattern is a bit of a wait-and-see. Saturday morning, September 19th, shows a promising 8ft WSW swell with a cross-off wind from the SE, but it's a long way out. The energy is strong at 2957, so keep an eye on it, but don't bank on it yet.
Honestly, if you're an advanced surfer and you can get out on the morning of the 10th, or the mornings of the 13th and 15th, you'll be in for some clean, powerful waves. The rest of the time, this exposed reef is going to be a battle with the wind. The big swell days with onshore winds could be more interesting for the kite surfers than us paddle guys.

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.
