The Lowdown
Righto folks, Rusty here. Let's have a look at what's on offer for Nyang-Nyang over the next couple of weeks.
First up, this is an advanced reef break that's pretty consistent but honestly, the whole period is a bit of a struggle. The wind's stuck on a cross-to cross-onshore angle for almost every session, meaning the surface is going to be choppy and messy. There's no standout day with clean, glassy conditions, so it's a case of taking what you can get. The combined swell energy is solid in the four-digit range, like 4184, so there's plenty of power in the water, but that wind is spoiling it.
We kick off on Wednesday, August 19th, with a solid 8.2 ft SW groundswell, but that ESE wind at 12 to 16 mph has it looking choppy and cross-onshore. Thursday the 20th is more of the same – 8.2 ft SW swell, but again that 16 mph ESE wind is making it a tough paddle. Friday the 21st morning drops a touch to 6.2 ft, but the wind is up to 19 mph, creating a lumpy cross-chop. Not ideal.
The whole of the following week, from the 23rd of August right through to the end of the month, is a real write-off. The wind stays cross-onshore, the swell drops off a bit, and every session is flagged as poor. It’s a long, bleak run with no decent windows.
You get a little flicker of hope on Friday, August 28th. The morning swell bumps back up to 7.9 ft from the SSW, and the wind eases to a gentle breeze of 9 mph. It's still cross-onshore, so it won't be perfect, but the energy is there (2777), and it'll be the least ugly it's been in a while. The period is 16 seconds, so there's some proper groundswell lines wrapping in, but the cross-onshore angle will still push that face shut a bit.
After that, the forecast from the 1st of September onwards looks more of the same cross-onshore chop. The swell sticks around 4.9 ft to 6.2 ft from the SW, but the wind just won't get its act together to give us a clean day. For this advanced crew, the main challenge is just finding a clean wave face amidst the chop. Honestly, given the persistent cross-onshore wind and the sheer power in the water, this setup looks a lot more interesting for kite surfing than paddle surfing right now.
Stay safe out there.

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.
