The Lowdown
Alright, mates, Rusty here. Let’s cut to the chase. We’ve got one spot on the map for the next couple weeks, Turtles, and it’s a proper rollercoaster.
The first look is on Monday morning, the 17th. We’ve got a clean 5ft SSW swell at 14 seconds. Wind is a light cross-off, so the surface is going to be glassy. Water temp's at 83°, a bit warmer than it usually is, so you won’t be needing a wetsuit. It's decent, but the energy is only moderate, so it’s a nice warm-up, not the main event.
Monday afternoon it fades a little and the breeze gets a bit pushy.
Now, here’s the one you’ve been waiting for. Tuesday the 18th, the morning in particular, is the peak of this whole period. The swell jumps to 8ft with a 16-second period. That’s proper groundswell. The energy is off the charts at 2750. The wind is still cross-off and light, so it’s going to be clean, hollow, and powerful. This is the day to get the good board out. It’s not a beginner wave, but for the intermediate and above, this will be the best session of the run.
Tuesday afternoon is still solid, but the magic is in that morning.
Wednesday the 19th, the swell flexes its muscle, hitting 10ft with an 18-second period. The energy is up over 5410. This is big, intimidating surf. Unless you’re a serious expert, this is a spectator day. It’s still clean but the power is something else. Thursday pulls back a bit to 8ft, but the wind and the bump make it more of a struggle.
From Friday the 21st, it’s a slow bleed. The swell hangs around 7ft to 8ft, but the period starts to drop and the wind stays onshore. It's still surfable, but the quality just isn’t there. The weekend is full of clean but average waves.
Early next week, the swell dips below 7ft and that long period starts to break up. The wind gets stronger, peaking at 40 km/h on Tuesday the 25th, which will chop things up. It’s a grind, not a gift.
That 4ft to 5ft range holds for the rest of the month, with moderate winds. There’s a little clean window on the morning of Saturday the 29th, but it’s small.
And rolling into September, it’s more of the same - 5 foot of swell and a constant cross-off breeze. You'll get your waves, but you'll be working hard for them.
The bottom line: it’s all about that Tuesday the 18th and Wednesday the 19th for the big stuff. After that, it’s about picking the right tide and having a paddle. The standout is clearly that Tuesday morning, so make sure you don't miss it if you can handle it.
Rusty out.

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.
