Nusa dua Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about Nusa Dua.

Right off the bat, we’ve got some decent SSW swell rolling in, but it’s not exactly clean and inviting. The water temp is sitting at a warm 80°, which is pretty normal for this time of year. That’s nice at least.

The whole first week or so is hampered by persistent cross-onshore winds, mostly from the ESE and SE, blowing at 15 to 25 km/h. This keeps things choppy and lumpy, especially on the morning sessions. There’s a bit of punch to the waves, with combined swell energy ranging from 1163 up to over 2000 (moderate to strong), but the wind just ruins the surface. There’s no standout day in that first run. Even on Thursday the 6th of August, when the swell bumps to 6 ft and the period hits 17 seconds, the wind is still onshore or cross-on, and the conditions are just poor. The wave comment says it all: “marginal” or “poor” most of the time.

On the 10th of August, we see a big jump in energy, hitting 4574 on the afternoon, with a 8 ft SSW swell rolling in at 18 seconds. That’s a lot of juice, but the cross-onshore wind at 12 mph keeps it messy. Not a day to get excited about unless you’re just driving past.

It gets bigger on the 11th of August, with the swell hitting 10 ft and energy up to 4513. That’s proper heavy water, but again, the wind isn’t cooperating. At this size, with those winds, Nusa Dua is really only for experts, and even then, it’s going to be a battle.

Things don’t really clean up as we move into the second week. The wind stays stubbornly cross-onshore. The standout potential comes right at the tail end of the run, on the 19th of August. We’re looking at a 10 ft SSW swell with a 18-second period, and energy of 5464, the biggest reading of the whole forecast. The wind eases slightly to a gentle breeze from the SE in the morning, with some rain showers. That’s the most promising moment, but it’s still a cross-onshore wind, so it’s not going to be perfect. It’s far off, so don’t book your flights just yet—long-range calls are always a bit shaky.

Nusa Dua is a consistent spot, a reef break that’s exposed to the SSW swell. The direction matches the optimum, so the potential is there. But with the wind pattern we’re seeing, the window for truly clean, glassy waves is pretty much non-existent in this 16-day window. There’s surf, there’s size, but the quality just isn't there for a paddle session. If the wind ever swung offshore (W), it would be a different story entirely.

The first few days have some 5 ft to 6 ft swell, but it’s not worth paddling out into that chop. We’re looking at a long stretch of mediocre conditions, so don’t get your hopes up until maybe the very last day. Blank runs like this are normal when the trade winds lock in.
