The Lowdown
Alright, Rusty here. Let's break down what's in the water for the next couple of weeks.
The first half of this forecast is a real bust. We've got a bunch of solid south-southwest swell, with the combined energy hitting strong numbers (3073), but the wind is just killing it. It's mostly a cross-onshore breeze, making everything choppy and messy. The conditions are rated poor. You'll see clear skies, but the ocean won't be clean. That first stretch, right through to the 27th of August, is basically a no-go for a good paddle.
Then, we get a change. The real standout, and the only one worth getting stoked about, is Nusa dua (reef) on the morning of Friday, August 28th. The wind finally turns offshore from the SSW, blowing light at 5 km/h, which should clean the faces right up. The swell is a solid 7 feet from the SSW, with a long period of 16 seconds. That's a proper groundswell, and with the offshore wind, the conditions are flagged as excellent for experienced surfers. The combined energy is strong at 2384, so there's plenty of power. This is a high-performance reef break, but it's an advanced spot, and it's often crowded, so expect a lineup.
The morning of Saturday, August 29th, also looks good. The wind holds from the SSW, a bit lighter at 10 km/h, but still a clean offshore. The swell is a touch smaller at 5 feet, but from the same direction, and the conditions are clean again. It's a solid follow-up session, but Friday morning is the clear winner.
The water temperature is 79°, which is pretty much average for this time of year, so nothing unusual there.
Later on, around August 31st and into September, the swell picks up again, but the wind swings back to a cross-onshore, so the quality drops off. The energy is there (3167 on the 31st), but the wind will chop it up. It's a bummer, because the potential is there, but the conditions just won't be right.
So, the bottom line: the first week is a washout with the wind. Your best bet is the morning of Friday, August 28th, at Nusa Dua. It's a short window, but when that offshore wind lines up with the strong SSW groundswell, it'll be a session to remember.
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.
