The Lowdown
Alright, so let’s get into Nyang-Nyang. This is a reef break for the crew with some experience, and it lights up on a good SW swell. We’ve got plenty of swell coming through, but the wind is going to be the boss for most of this run, and it’s not our friend.
We’re looking at a persistent cross-onshore breeze from the ESE and SE that’ll keep the surface chopped up and lumpy. Water temp is 78°F, which is spot on for the season. There’s a heap of energy in the water, with combined swell energy readings regularly up in the thousands, so there’s plenty of push, but the wind is just messing with the shape.
Monday 17th and Tuesday 18th, the swell comes in from the SSW to SW at 5ft to 6ft, with a long period of 14-16 seconds. That’s proper groundswell for the reef, but that cross-onshore wind makes it a messy affair. Not really what you’re looking for. Wednesday 19th and Thursday 20th, the swell really kicks, hitting 8ft to 10ft from the SW with a very long period of 16-18 seconds. That’s big, powerful, and only for the brave. The wind stays cross or cross-onshore, so you’re in for a rough, challenging session.
The one true highlight, and the only time I’d really get excited, is Sunday 30th August and Monday 31st August. The wind drops to a gentle breeze from the SSE, still cross-on but much lighter. You’ve got a solid SW swell of 6ft to 8ft with that same long period of 16-18 seconds, and combined energy readings are high. For a reef break like this, that long-period SW groundswell is pure gold. The waves will be heavy and powerful, with long waits between sets making the paddle out manageable. It won’t be perfect, but it’ll be the cleanest we’ll see in these two weeks. Crowds are only sometimes an issue here, so you might have a few mates out but nothing too hectic.
After that, the first few days of September see the wind pick back up and the swell fade, so that last weekend in August is your best bet. If you’re an advanced surfer and you’ve got patience, that’s the time to point the car towards Nyang-Nyang.

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.
