The Lowdown
G’day, Rusty here. Let’s break down what’s happening at Nyang-Nyang over the next couple of weeks. This is an advanced reef break that really needs a clean SW groundswell to shine. Water temp is about 79°, which is right on average for the season—nothing out of the ordinary.
Truth is, the first week is pretty average. The wind is stuck cross-on from the ESE, often blowing a fresh 19 mph, which leaves the surface lumpy and choppy. There’s a solid SW groundswell running, with wave heights between 6 ft and 7 ft and a long period of 14 to 16 seconds, but with that wind, it’s never going to be clean. The wave energy is moderate to strong—numbers like 1862 and 2192—but the quality is poor. From Monday the 14th through Tuesday the 22nd, it’s all pretty much a miss for paddle surfing. You’d have more fun on a kite in that cross-offshore breeze.
There’s a gap from Tuesday the 22nd onward where conditions stay marginal, with the same cross-on wind pattern.
Now, here’s the big one. Mark Sunday the 27th of September. That afternoon, the swell jumps to 10 ft from the SSW with a period of 20 seconds—that’s very long period groundswell—and the combined energy hits 7566, which is strong to very strong. The wind is a light 9 mph from the SE, still cross-on but much lighter. With that long period, the waves will be fat, powerful, and wrapping into the reef nicely. A 10 ft face is expert-only territory, and the long period means it’ll be hard to paddle into—best for the experienced crew. Crowds are sometimes a factor here, so expect some company. This is the standout of the whole outlook, though being over a week out, it’s promising but not set in stone.
Monday the 28th holds similar 10 ft swell from the SSW, but the period drops to 17 seconds and the wind picks up to 12 mph, so it’s a step down in quality. Still big, but chop will creep in.
After that, we’re back to more cross-on conditions with 7 ft to 7 ft swell through the end of the period. Not much to write home about.
Bottom line: the first week is a washout unless you’re kiting. The real gem is Sunday the 27th afternoon—big, long-period swell and lighter wind. That’s the one to keep an eye on.
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.
