The Lowdown
G'day, I'm Rusty, and I've been staring at the charts for your local stretch. Let's get into it.
Straight up, this is a tough run. The whole 16-day window is looking like a battle against the wind. The swell is there, but it's almost always coming in with a cross-onshore breeze that's going to chop it up. The water temp is sitting right around 79°, which is bang on average for this time of year, so no surprises there.
The first real pulse of energy you'd want to look at is kicking off on the morning of Thursday, August 13th. We've got a solid 8ft S swell rolling in with a very long 17s period. That's proper groundswell with a heap of energy behind it (3463). The problem is that ESE wind is howling at 25 km/h, cross-on, making it a mess. It's an advanced-level reef break, Nusa dua, and with that size, it's only for the experienced crew. The period is so long that it might be better suited to a point or reef, but the wind is the killer here. The wave comment says it all: "poor surf conditions". It's a tough one to recommend.
As we move through the first week, the pattern is consistent. The swell sticks around, dropping from 8ft to 7ft and then 7ft over Friday and Saturday, but the wind stays stubbornly cross-on from the SE or ESE. The period, however, remains impressive, often in the 15-17s range, which means the energy is real (often in the 2000-3000 range). But with that constant wind, the surf is always "marginal" or "poor". Thursday morning, August 13th, is the standout, but only because it's the biggest and most powerful. It's not clean, but it's the most powerful chunk of ocean we've got.
The second week doesn't offer much relief. From Monday, August 17th, the swell drops down to 5ft and smaller, and the wind just keeps blowing. The energy drops off, too, with the combined energy falling below 1000 for many periods. The wave comments are consistently "poor surf conditions". There's a tiny uptick on Wednesday, August 19th, with a 8ft SSW swell and an 18s period, combined energy of 3305, but again, the wind is cross-on. It's a tease.
To be honest, for the next 16 days, the only break that's even on the radar is Nusa dua. It's very consistent, but the wind is a constant problem. If you're an expert and you're desperate, the morning of Thursday, August 13th, is your best bet for the biggest, most powerful waves. But don't expect anything clean. For the rest of us, this is a dry spell. The forecasts can change, but right now, it's a waiting game.
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.
