The Lowdown
Alright, listen up, it’s Rusty here. I’ve been checking the charts for Nusa Dua, and I gotta be honest with you, it’s looking a bit on the messy side for the next couple of weeks. There's no shortage of swell, but that wind is going to be the deciding factor, and it's blowing the wrong way for a lot of it. It's a real mixed bag.
The water's about 79°, which is normal for this time of year. Nothing weird going on there.
We kick things off on Sunday the 16th. There’s a solid 7ft SSW groundswell, with a long 16-second period and plenty of energy behind it at 1935. The issue is the ESE wind is blowing straight onshore at 9 mph, which is going to put a real chop on it. It's a marginal call at best. The afternoon drops to 6ft, but the wind picks up to 12 mph, still onshore.
Monday the 17th is a wash. The swell drops a bit, and the wind goes cross-onshore, leaving it lumpy and bumpy. You're better off staying home.
Tuesday the 18th, the energy is back up, but the swell is a weak 4ft in the morning. The wind is cross-onshore and the surface is bumpy. The afternoon brings a slightly better 6ft, but the wind stays cross-onshore and it’s still choppy.
Now, Wednesday the 19th is where you start to see some size. We get a 7ft swell in the morning with an 18-second period and energy over 3000. But that cross-onshore wind is still messing it up. By the afternoon, it's 8ft with more energy, and the wind goes more onshore. It's powerful, but it's going to be rough.
Thursday the 20th sees the biggest swell of the period, hitting 8ft in the morning. But that cross-onshore wind at 12 mph is going to make it a stormy, bumpy mess. This is expert territory only. The afternoon eases to 7ft but it's still messy.
Friday the 21st is a write-off. The wind is howling at 19 mph onshore in the morning, and the afternoon isn't much better with 16 mph cross-onshore winds. You'd need a kite for this, not a board.
The weekend isn't any better. Saturday has 7ft swell with strong onshore winds, and Sunday is the same story with a cross-onshore breeze. It's just poor.
The second week continues the trend, with smaller surf in the 4ft to 6ft range. The wind stays mostly cross-onshore, so it stays lumpy. There are a couple of glimmers, like the morning of the 30th, which has a long 19-second period, and the 31st, when the wind drops to 9 mph. That last call on Monday the 31st might be the pick of the bunch, but even it is only a marginal call.
So, bottom line for Nusa Dua: there's plenty of swell, but the wind is just not cooperating for most of this window. The standout for size is definitely the 20th with that 8ft, but it's going to be an onshore, choppy mess. Honestly, if you're looking for a clean surf, you might want to wait for the very end, around the 31st, when the wind eases. But it's still not offshore.
Nusa Dua is a reef break, so it handles the swell, but it needs clean conditions to really show what it’s got. The long-period swells we're seeing are best on a reef or point, which is what we have, but the wind is the great equalizer. It's one of those times to be patient. The place can turn on in a heartbeat when the wind finally swings around, but for now, it's just not happening.
Rusty, signing off.

Information about the Nusa dua Surf forecast
The above surf forecast table for Nusa dua provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Nusa dua can be found by selecting the local surf guide option on the grey menu. Our Nusa dua 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 (Nusa dua) 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 Nusa dua 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.
Nusa dua is 12 km (7 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.
