The Lowdown
Alright, Rusty here. Let’s get into it.
Alright, we’re looking at a pretty grim stretch ahead for Nyang-Nyang. This is a reef break that needs a clean, offshore wind to really shine, but for the next week and a half, we’re locked into a cross to cross-onshore breeze that’s going to keep things messy. The water is sitting at 78°, which is just a touch cooler than average for this time of year.
We’re starting off with a very long period SW groundswell on Thursday 20th August, pushing 8ft, with a massive 3855 (strong) energy reading. But the ESE cross-on wind is 12 to 16 mph, making it choppy and dangerous. This is advanced territory, and the conditions are just poor. This continues through the rest of the week and into the early part of the following week. There’s no standout session here for a while.
The wind stays stubbornly cross-on, from the ESE or SE, all through the 20th to the 25th. The swell is solid, but the quality is junk. The 21st Friday sees a 8ft SSW groundswell with a 17-second period, but the wind is a mess. Saturday 22nd has a morning window with a cross-shore wind, but it’s only a “marginal” call, and the swell is still mixed up.
We finally get a bit of a break on the 27th of August, with a smaller, longer-period SW groundswell (2ft to 4ft, 19-21 seconds), but the wind is still cross-on from the SSE at 9 mph. The energy drops to 1199-1931, but it’s still a fairly clean, albeit gentle, cross-onshore chop. It’s still not what you’d call good.
Now, the real tease comes at the end of the month. On Monday 31st August, the afternoon sees a 8ft SW groundswell with a 20-second period and a massive 5407 (very strong) energy reading. On Tuesday 1st September, we’ve got a 10ft SW swell with a 17-18 second period, and energy readings of 5314 and 4856. This is a massive, powerful groundswell. But the wind remains a cross-on SE breeze. The best the forecast can say is “marginal” for the morning of the 1st, with a 4/10 score. It’s just too big and onshore for a clean experience. This is expert-only, and even then, it’s going to be a battle.
After that, the swell starts to taper off into the first week of September, with energy dropping and the wind still ruining the surface. There’s a brief window on the 4th of September afternoon with a 4ft SSW groundswell and a 17-second period, but the cross-on wind is still there.
Honestly, for the entire 16-day window, there’s not a single day where the wind is offshore or light. The best we get is a “marginal” call, and even then, the cross-on wind is a constant spoiler. The only real highlight is the sheer size and energy of the swells around the end of August and 1st September, but that’s a big wave mission for experts only, and it will be a choppy, onshore mess. For the average surfer, there’s nothing to get excited about here. The wind is the enemy.
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.
