The Lowdown
Hey, Rusty here. Let’s talk surf. Right now, Nyang-Nyang is struggling. The whole first week and into the second is hit by cross-onshore winds that are turning decent swell into a choppy mess. The waves are there, but they’re ugly.
First real chance is Thursday the 17th of September. Swell is 6ft to 7ft from the SW with a long period of 15 seconds – that’s real groundswell. The combined energy is moderate to strong (1641 to 1865), but the wind is cross-on (ESE to SE at 15-16 mph), so it’s bumpy and wind-affected. Water temp is about average for the season. Nyang-Nyang (Indonesia) is a reef break, so it handles swell, but with this wind, it’s a battle.
Friday the 18th of September morning is the best in the first week. Swell drops to 6ft from the SSW, period 14 seconds, and wind eases to 9 mph from the ESE. Still cross-on, so only fairly choppy, but the energy is moderate (1073). It’s marginal – you might snag a clean one. Not a standout.
There’s a big gap of poor surf from Friday afternoon through the end of the first week. Swell sticks around, but the wind stays cross-on. Then around Sunday the 20th of September, swell jumps to 7ft to 7ft from the SW with a very long period of 16 seconds – serious energy (2269 to 2374). But again, cross-on wind. Not clean.
The real standout is Sunday the 27th of September. A big SSW swell hits 12ft with an 18-second period – that’s a monster groundswell. Combined energy is enormous (7420). This is expert-only territory. It’s a reef break, so it’ll handle the size, but the wind is still cross-on (SE to SSE at 12 mph). The morning is only marginally surfable – the internal nod is decent, but afternoon is poor. For a reef, that long period will set up proper lines if the wind were offshore, but with cross-on, it’s a tough paddle and a lot of white water. Crowds are possible here.
After that, Monday the 28th of September still has solid 8ft to 8ft swell from the SSW with a 16-second period, but again, cross-on wind. A step down.
For beginners, this whole run is too big and too messy. For experts, the 27th is your best shot, but don’t expect glassy conditions. The wind just won’t let up. Keep watching – it usually doesn’t stay this choppy for long.
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.
