The Lowdown
Alright, Rusty here. Let’s talk about what’s in store for the next couple of weeks. We’ve got one spot on the radar, Nusa Dua, and it’s a reef break that demands respect. We’re looking at a long, choppy stretch of drizzle before things clean up for a very specific window.
Right now, through the start of the period, the water temp is sitting at a pretty toasty 80°F, which is bang on average for this time of year. It’s a consistent, exposed spot, but for the first week and a half, the wind is a real problem. From Monday the 31st of August right through to the 8th of September, we’ve got a persistent cross-onshore breeze – mostly from the ESE to SE at 12 to 16 mph – churning things up. It’s going to be choppy, bumpy, and just not very enjoyable. The swell itself isn’t bad – we’re seeing solid SSW groundswell running 4 ft to 7 ft with a long period of 15 to 18 seconds – meaning it’s packing plenty of energy. The combined energy readings are in that moderate to very strong range, but the wind is just wrecking the surface. For most of these days, the surf is rated as poor, and there are a lot of marginal tide windows on offer too. Honestly, for the first week, it looks more like a kite-surfing scenario than a good paddle session; the wind is strong and consistent enough for those guys, but for us, it’s a waiting game.
Hold onto your board, because things are about to get interesting. The standout is shaping up for the morning of Wednesday the 9th of September. That’s when we see the stars align. The wind swings around to a light 6 mph from the SSW, putting it cross-offshore. That’s going to clean up the surface beautifully. The swell will be a punchy 7 ft from the SSW, still with a quality 16-second period. The combined energy is pumping hard, so there’s a ton of power in the water. This is excellent surf for experienced surfers – anything over 8 ft is strictly for experts, but 7 ft at a reef like this is proper, challenging juice. The only downer is that this break is listed as "often" having crowds, so on a day like this, expect some company in the lineup.
After that Wednesday morning peak, the wind gets a bit iffy again. The next few days see that cross-onshore mess return and the swell stays strong, but it’s just not as clean. By the second week, from the 11th to the 15th of September, the window narrows. We’re still seeing consistent SSW swell around 5 ft to 7 ft, but the period drops to 14-15 seconds, and that persistent SE wind is back. The quality just isn’t there for a recommendation. Some afternoons on the 11th and 12th show marginal conditions, but nothing to write home about compared to that Wednesday morning.
So the one true standout is the morning of the 9th of September at Nusa Dua. Don't sleep on it. Everything else is pretty average with that wind.
Rusty.

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.
