The Lowdown
Alright folks, Rusty here. Let’s talk about what’s going on with Nyang-Nyang.
Right off the bat, I gotta be straight with you – this is a tough stretch. The overall picture is dominated by a persistent cross-onshore wind that just won't let up, and it's blowing out an otherwise solid run of swell. We’re looking at a 16-day window with no real standout sessions, but there are a couple of afternoons that might just be worth a paddle if you're desperate.
The first real chance we get is on Friday, August 15th. The morning is a write-off, but the afternoon might offer a glimmer. The swell is still solid at 7ft from the SSW with a 15-second period, but the energy is still high at 2378. The wind is a cross-on 20 km/h SE breeze, which is still messy, but it’s the first time the forecast nudges up to a "marginal" call. It's not pretty, but it's the best we’ve seen.
Then, on Saturday, August 16th, the morning shows a bit more promise. Swell is 8ft from the SSW with a 17-second period, and the wind drops to a gentler 15 km/h SE breeze. The wave energy is strong at 3302. It’s still cross-on, but "fairly choppy" is a step up from "choppy." This is the pick of the first week, but it’s still a long way from clean.
After that, we get a bit of a lull in swell size around August 17th and 18th, with waves dropping to 5ft to 6ft, but the wind is still cross-onshore. The energy drops to between 1110 and 2944, which is moderate but still ruined by the wind.
The swell pumps back up from August 19th, with 8ft to 10ft SSW/SW groundswells, and the energy goes through the roof – 3841 to 4631. These are big, powerful days. But the wind is still a problem. On Wednesday, August 20th, the afternoon session actually sees the wind turn to a cross-shore ESE breeze at 20 km/h, and the forecast gives it a 3/10. That’s the highest score in the whole run. The swell is 8ft from the SW with an 18-second period, so the power is immense. This is the only time in the whole outlook where the conditions might be semi-rideable for a crew that can handle a big, chunky, cross-shore chop. It’s still a messy, expert-only affair.
The rest of the run into the end of August is a sad story. The wind stays cross-onshore, and the swell is consistently big, but the quality is just "poor." The final few days from August 25th onward see the swell drop off, but the wind doesn't change. It’s a long, frustrating wait.
The water temp is sitting at 78°, which is just about average for this time of year, so no surprises there.
So, what’s the call? If you’re an expert who can handle serious power and cross-shore chop, the afternoon of Wednesday, August 20th is your only real shot. For everyone else, this is a two-week blank. The swell is there, but the wind has it locked up. It tends not to stay this bad forever, so don't give up hope, but for now, I'd keep the board in the bag.
Rusty.

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.
