The Lowdown
Alright, Rusty here. Let’s break this one down.
Let’s be straight—this stretch looks tough for clean rides. There’s plenty of heavy water coming in, but the wind is gonna be a real pain, blowing cross-onshore nearly the whole time. You’ll see size and power, but it’s gonna be a fight with the chop.
Starting Friday the 21st of August at Nyang-Nyang (reef) . Water temp is around 78°, normal for this time of year. First light, we’ve got a 6ft swell out of the SW with a very long 15 second period—that’s proper groundswell. The combined energy is cranking at 2967, but that ESE wind at 12 mph is cross-onshore and it’s wrecking the surface. By afternoon the swell jumps to 8ft from the SSW with a 17 second period, but the wind hits 16 mph and it's game over for quality. Experts only here.
Saturday the 22nd and Sunday the 23rd are rinse and repeat. Swell sits around 7ft to 7ft, period stays long, but that cross and cross-onshore wind (12 to 16 mph) keeps everything choppy. Mornings are marginal, afternoons are a write-off.
The whole next week, right up to the 30th, is a no-go for quality. Swell stays solid, often over 6ft, and the wind just doesn’t let off. The energy numbers are still big (over 1000 and into the 3000s), but with that cross-onshore breeze, this setup looks more interesting for kite surfing than paddle surfing.
Then comes the 31st of August. Swell drops way down to 3ft from the SW, but check the period—19 seconds! That’s crazy long groundswell. Wind eases to 9 mph from the SE, still cross-onshore, but it’s lighter. Energy is moderate at 1129. It’s still choppy, but for a reef like Nyang-Nyang, that long period brings shape and power. It’s a “maybe go for a look” session.
Into September, Tuesday the 1st has 6ft from the SW at 17 seconds, and Wednesday the 2nd is a beast with 8ft from the SW at 17 seconds—energy hitting 4072. But again, cross-onshore wind. All power, no polish.
The best chance in this whole 16-day window? Look at the morning of Saturday the 5th of September. Swell is 6ft from the SSW at 18 seconds (very long period, groundswell) and the combined energy is 3000. Wind is SE at 12 mph and cross-onshore, so not perfect, but it’s the best of a bad bunch. That reef will handle the long period, pushing grunty lines through, but expect a cross-chop. It’s a local-knowledge-only kind of day.
Overall? No perfect windows. If you’re an expert and you’re aching for a paddle, the 31st of August morning or the 5th of September morning are your best bets. Otherwise, wait for a better forecast.
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.
