The Lowdown
Hey crew, Rusty here with the goods.
Alright, we’ve got waves on the horizon, but the wind is going to be the story. It’s blowing cross-off from the southeast nearly the whole run, which keeps the faces clean, but it’s a stiff breeze. The charts are all saying “marginal surf forecast or questionable tide conditions,” so you’ll have to work for it.
The one to focus on is Turtles. It’s a very consistent reef break, and it’s going to see all the energy. The absolute best bet is Tuesday morning, August 11th. We’re looking at a chest-to-head-high-plus 3.0m SW groundswell with a long 19-second period. The energy is massive – over 6000 – so it’ll be powerful. Water temp is about 82°F, pretty average for the time of year. The catch is the wind is a fresh 18 mph cross-off, so it won’t be perfect, but clean enough for some serious turns. You’ll have some company, too, as crowds show up sometimes. This Tuesday morning session is the standout of the whole 16 days.
After that peak, the swell settles a bit. Wednesday morning, August 12th, still has a solid 1.8m SSW swell with a 16-second period, and the wind drops to a moderate 15 mph. It’s still cross-off, so it’s doable, but it’s not the same quality.
We get a couple more strong pulses. Thursday afternoon, August 13th, jumps back to a 3.0m S swell, and Friday afternoon, August 14th has a 2.5m S swell with a 14-second period and energy over 5600. That’s a lot of power, but the wind is cranking at 21 mph. Good for a surfer who doesn’t mind the wind and wants some grunt.
Into the second week, from Tuesday, August 18th to Thursday, August 20th, we see another run of strong SSW swell, 2.3m to 3.0m, with 16–17 second periods. The energy is all in the high hundreds to low thousands. The wind stays in the 18–21 mph range. It’s promising, but it’s a week or more out, so don’t book your flights yet.
With the swell size consistently over 1.5m and often pushing 2.5m to 3.0m, this is expert territory. Beginners, sit this one out. The long periods mean the waves will have great shape and plenty of punch. Turtles being a reef will handle the long-period groundswell well, which is a bonus.
No real gaps in the action, just a constant run of surf with a constant breeze. It’s a solid window, not a classic one, but there’s plenty of power to go around.
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.
Turtles is 40 km (25 miles) from the city of Pelabuhanratu. If you plan a holiday in West Java, look for hotels and other accommodation in Pelabuhanratu. Pelabuhanratu has rooms for a wide range of budgets as well as car hire and transport links.
