The Lowdown
Right now, Nyang-Nyang is lookin’ at a rough stretch, plain and simple. The winds are all cross-on, which is putting a chop on everything, and the forecast is calling the conditions marginal or poor. Water temp’s sitting at 26°, which is right around what you’d expect for this time of year, so no surprises there. The energy is moderate at best for the first few days – around 1455 combined – but it’s just not lining up clean.
The 16th and 17th are a write-off. Swell’s around 1.8m to 2.1m with a 15-second period, but that cross-on breeze is chewing it up. You’re gettin’ some size but it’s messy, and the tide’s not helping. Scores are low for a reason.
The 18th through the 22nd are more of the same – lumpy, choppy, and not worth paddling out for anything serious. Swell drops a touch on the 18th to 1.2m, then builds back up. The energy stays in the moderate range, mostly between 954 and 1500, but it’s all cross-on and the quality is just not there.
Now, things start to get interesting on the 20th. The swell jumps to 2.1m and the period’s a solid 16 seconds, with energy climbing to 2363. Still cross-on, still choppy, but you can feel something building. By the 23rd, we’ve got 2.2m SSW with a 16-second period and energy up around 2371. The size is there, but it’s still not clean.
The real standout window is the 26th of September through the 1st of October. On the 26th, the energy jumps to 4810 with a 20-second period, and even though it’s cross-on, the swell is 2.2m and moving. The 27th is the biggest of the whole run – 3.0m SW with a 18-second period and energy cracking 6724. That’s serious power. But heads up – this is over 2.5m, so this is expert-only territory. Beginners should sit this one out. The period is long, 18 seconds, so it’s a proper groundswell. At a reef like Nyang-Nyang, that can be a good thing, but the cross-on wind is still going to be pushing bumpy shoulders. It’s not going to be glassy.
By the 1st of October, it’s still big – 2.2m to 2.4m with 17-second periods and energy around 3451 – but the cross-on wind is still there. It’s powerful, but it’s not going to be a picture-perfect day. The long period means long gaps between sets, which can make the paddle out a bit easier, but also means the sets that do come are heavy.
Honestly, if you’re an experienced surfer who can handle a bit of chop and a lot of water moving, the 27th is the biggest and most powerful day. It’s not going to be clean, but the size is there. The 26th and the 1st are also solid, but they’re all going to be a bit ruffled.
For the average surfer, there’s not much to get excited about in the first week. The second week is where the energy comes, but it’s all tied to that cross-on wind. Short of a lucky tide, Nyang-Nyang is going to be a grinder, not a glider.

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.
