Nusa dua Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s coming our way.

Honestly, the next week and a half is a bit of a grind. There’s swell on the table, but that persistent cross-onshore wind from the ESE and SE is gonna keep things messy at Nusa dua. The water temp is sitting right on 80°, which is pretty much bang on average for this time of year, so no surprises there.

The first real chance to even think about paddling out doesn’t really show up until Friday the 31st of July, and even then it’s a marginal call. You’re looking at a 4 ft swell from the SSW with a solid 17-second period, which is proper groundswell energy – you can feel that in the water. But that cross-on wind is still going to mess with the surface. The combined energy is sitting at 1197 (moderate wave energy), so there’s push, just not the clean face you’d want.

That Saturday morning, August 1st, might be your best bet early on. The wind is straight onshore at 12 mph, which is a bit ugly, but the swell is 5 ft from the SSW at 16 seconds, and the combined energy jumps to 1214. Still, it’s a marginal call.

The real standout, and I mean the one to circle on the calendar, is Saturday the 8th of August. The afternoon session looks like the best of the whole run. We’ve got a 8 ft SSW swell with an 18-second period – that’s a serious groundswell, long and powerful, with combined energy roaring up to 3834 (strong wave energy). That’s proper heavy water. For a reef break like Nusa dua, that long period will wrap in beautifully, but it’s strictly for the experts at that size. The wind is cross-on at 12 mph, which is the same old story, but the raw power is undeniable. Be ready for a crowd too – this spot is often packed, and with a swell like that, it’ll be busy.

Before that, Sunday the 2nd of August also has a 7 ft SSW swell at 17 seconds, but the wind is worse, and the quality is poor. Don’t get too excited about that one.

The second week is a mix of similar conditions – plenty of 5 ft to 8 ft SSW swell, consistently cross-on wind, and combined energy that stays in the strong range (over 1000, often over 2000). But the lack of clean, offshore conditions means it’s more of a “watch the forecast” situation than a “go now” one.

So, bottom line: if you’re an experienced surfer who can handle a bit of chop and a lot of power, the afternoon of August 8th is your window. The rest of the time, it’s either poor surf or marginal. Keep an eye on the wind, because if that shifts, this place could fire.
