The Lowdown
Alright, Rusty here. Let’s take a look at what’s lining up.
First off, we’ve got a solid stretch of SW groundswell headed our way, but the wind is going to be the main character in this story. For the most part, it’s coming from the ESE, which puts us in a cross-on position at Nyang-Nyang. That’s going to mess with the surface, making things choppy. The water temp is sitting at 78°F, which is pretty much bang on average for this time of year, so no surprises there.
The week kicks off Tuesday the 18th with a decent pulse of swell – we’re looking at 6ft of SW groundswell with a long 16-second period. That’s a proper groundswell, and the energy is pumping with a combined energy of 2637. Problem is, the wind is cross-shore at 12 mph, so it’s not going to be glassy, just marginal. By the afternoon, the wind picks up to 16 mph and swings cross-on, making it a write-off.
Wednesday the 19th sees the swell size jump up. Morning has 8ft of SW swell on an 18-second period – that’s a big, powerful groundswell. Combined energy is massive at 4266. But the wind is cross-on at 16 mph, so it’s choppy and messy. This is not a beginner wave; at 8ft, it’s pushing into expert territory, especially with that long period. The afternoon gets even bigger, hitting 10ft and 4660 energy, but same story with the wind. Not a good time.
Thursday the 20th through Sunday the 23rd is basically the same pattern. Solid SW swell hanging around, 6ft to 8ft, but that cross-on wind just won’t let up. The energy stays high, with numbers like 3808 and 3721, but the surface is going to be lumpy and uninviting. There’s a brief moment on Saturday morning the 22nd where the wind eases to cross-shore at 19 mph, but that’s still a fresh breeze and creates a lumpy cross-chop.
Honestly, the first week is a bit of a battle. The swell is there, and it’s got plenty of energy, but the conditions are holding it back.
Now, looking into the second week, things start to get a bit more interesting. From Thursday the 27th onward, the wind starts to show some promise. On Friday the 28th, we get offshore winds from the S at 9-12 mph. That’s a game changer. The swell is still solid at 6ft from the SW with a 15-second period. The combined energy is 1412. That’s our first real window of clean surf. It’s still a big wave, so not for the faint-hearted, but if you’re an experienced surfer, Friday morning is looking like the standout of the whole run.
Saturday the 29th morning has lighter wind, 6 mph from the SE, which is cross-on but only a light breeze. The swell is 6ft. It’s not perfect, but it’s way more manageable.
Sunday the 30th brings another solid push of SW groundswell, 6ft on an 18-second period. The wind is offshore from the S at 12 mph. This is a long-period groundswell, so the sets will be powerful and well-spaced. It’s a reef break, so that longer period will actually work in its favor, giving you clean, lined-up walls. This is the other top pick.
Heading into the final days of the month and into September, the pattern holds. We’ve got consistent SW swell and a lot more south in the wind, giving us more offshore sessions. Monday the 31st morning has a 7ft SW swell with offshore wind at 9 mph. The energy is 2354. Another good one for the advanced crew. Tuesday September 1st bumps up to 8ft with 3663 energy. Still offshore or light cross-on.
So, if I’m picking the best of the bunch, it’s got to be Friday the 28th of August with that offshore wind and solid groundswell, and Sunday the 30th of August for the same reason. Clean, powerful, and well-shaped at a reef that loves a long-period SW swell.
Crowds at Nyang-Nyang can be an issue sometimes, so expect company if the wind holds.
Rusty.

Information about the Nyang-Nyang Surf forecast
The above surf forecast table for Nyang-Nyang provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Nyang-Nyang can be found by selecting the local surf guide option on the grey menu. Our Nyang-Nyang 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 (Nyang-Nyang) 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 Nyang-Nyang 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.
Nyang-Nyang is 16 km (10 miles) from the city of Kuta. If you plan a holiday in The Bukit - Bali, look for hotels and other accommodation in Kuta. Kuta has rooms for a wide range of budgets as well as car hire and transport links.
