Nusa dua Surf Forecast and Surf Report

G’day, I’m Rusty. Let’s have a look at what’s cooking for the Nusa Dua region over the next couple of weeks.

Right off the bat, I gotta be straight with you—this forecast is a bit of a grind. There’s a solid, long-period groundswell coming in from the SSW, packing a heap of energy, but the wind is gonna be a persistent pain. For the first week and a half, the breeze is almost always cross-onshore or onshore, which means the surface is gonna be choppy and messy. It’s not a total write-off, but you’re gonna have to pick your moments carefully. The water temp here is sitting around 78.4°, which is pretty average for this time of year—nothing unusual there.

Looking at Saturday the 22nd of August, we’ve got a 6.9ft SSW swell with a period of 16 seconds—that’s proper groundswell energy (combined energy 2144). That’s a lot of push, but the wind is a moderate onshore breeze from the ESE at 12.4 mph. That’s going to wreck the lineup, making it tough and bumpy. The wave comment is “poor surf conditions,” so honestly, I’d give this one a miss.

Sunday the 23rd doesn’t improve much. Still a 5.9ft swell from the SSW, still cross-onshore winds. The energy is there (1707), but it’s choppy and the conditions are marginal at best. Monday and Tuesday are more of the same—decent swell height (4.9ft to 5.9ft) but the wind keeps swinging cross-onshore, so you’re looking at choppy, unreliable surf. The combined energy drops a bit, down to around 1176 on Tuesday morning, but it’s still enough to feel, just not clean.

Wednesday the 26th sees the swell drop to 4.9ft and the period shorten to 14 seconds. The wind is onshore again, and the energy is weakening (941). Still poor. Thursday the 27th has a weird one—swell drops to 3.3ft but the period jumps to 20 seconds in the afternoon, firing up the energy to 2242. That’s a long, lully groundswell, but with cross-onshore wind and only 3.6ft, it’s marginal. Might be worth a look if you’re desperate for a wave, but don’t expect much.

Now, Friday the 28th of August is where things get interesting. We’ve got an 8.2ft SSW swell with a 16-second period and combined energy of 3235—that’s strong. The wind is a gentle cross-onshore, so it’s still a bit choppy, but the energy is real. That size is getting into the “experts only” zone, especially at a reef break like Nusa Dua. It could be a standout if the wind lays down a bit more, but with the cross-onshore, it’s a gamble. The score is a 2, which is the highest we’ve seen so far, but still not a full recommendation.

Saturday the 29th and Sunday the 30th see the swell dropping back to 5.9ft and then 4.3ft, with the same cross-onshore wind. The energy fades (1362 down to 738), and the surf gets poor again. Monday the 31st has a weird spike—3.6ft swell but a 21-second period in the morning, giving energy of 1301. That’s a very long-period groundswell, which can be tricky at a reef break, but it might offer some clean lines if the wind ever cooperates. The afternoon picks up to 4.6ft with 20 seconds and 1805 energy, and the wind is a gentle cross-onshore. This is one of the better options in the first week, but still marginal.

The first week of September starts with a bang. Tuesday the 1st of September has a 6.9ft swell from the SSW with an 18-second period and energy of 2890—strong stuff. The morning wind is a gentle cross-onshore, so conditions are “fairly choppy” but not terrible. The score is a 2 again. This could be a good session if you’re an experienced surfer, but the wind isn’t ideal. Wednesday the 2nd drops to 6.6ft with 17 seconds and 2312 energy, but the wind picks up to moderate cross-onshore, making it choppier.

After that, the swell fades through the 3rd, 4th, and 5th of September, dropping to under 3.3ft with weak period and low energy. The wind is gentle
