The Lowdown

Alright, Rusty here, let’s get into it. We’ve got a classic run of solid, powerful groundswell on the way. The water temp is sitting right on 72°, which is pretty much normal for this time of year, so no surprises there.

The standout is Turtles (reef), an advanced spot that’s exposed to the swell. The first half of the week is your absolute best bet. We kick off Thursday morning, the 20th, with a solid 8ft swell from the WSW, a 16-second period, and a very healthy combined energy of 3192 (strong). The wind is light offshore from the east, so those waves will be clean and lined up. This is excellent surf for experienced surfers. This is the pick of the whole run.

The quality holds through Friday the 21st. Swell drops to 7ft, still from the WSW, still a 15-second period, and still with that gentle offshore breeze. Energy is still strong at 2043. The waves will be a touch smaller, but still very well-shaped and clean. Saturday morning the 22nd starts off with a clean 6ft swell from the SW, but the wind goes light and cross-off. The real trouble hits Saturday afternoon as the wind swings cross-onshore, turning the waves choppy. From there, the wind gets messy. Through Sunday the 23rd and Monday the 24th, the surf gets smaller and bumpier, with cross-off or cross-shore winds making it hard to find a clean face. The energy drops back into the high hundreds to low thousands.

Tuesday the 25th is a poor day, and Wednesday the 26th sees a new pulse of energy (2935) but the wind is fresh cross-shore and lumpy, so it’s not a surfer’s wave. Thursday the 27th brings another 8ft WSW swell, with strong energy (3110) and a clean cross-off breeze in the morning. That could be a good session for the experienced crew, but the wind stiffens in the afternoon. The run from Friday the 28th through to the end of the forecast is a bit of a mixed bag. There are pulses of swell, but the wind is often cross-on or cross-shore, leaving the surf lumpy and choppy. Monday the 31st morning has a big 8ft swell from the WSW with a 18-second period and massive energy (4354), and the wind is clean cross-off – that’s another proper groundswell day, but the crowd profile at Turtles is “often,” so you’ll have company. The first week of September sees a slow decline, with the wind staying onshore or cross for most of the afternoons. The best sessions will be the mornings, especially on the 1st and 2nd, when the wind is lighter.

For the advanced surfer, the standout mornings are Thursday the 20th, Friday the 21st, and Monday the 31st. The long period of the swell (15-18 seconds) means this is a classic groundswell, and a reef break like Turtles is the perfect place for it. The sets will be a bit more spaced out, but the energy and shape will be top-notch. This is not for beginners – the swell is over 7ft for most of the run, and often over 8ft, so it’s strictly expert territory.

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.
